Intel Inside--Classroom

Forbes.com

By Elizabeth Corcoran, 10.17.08, 05:43 PM EDT

The chip company is pursing a classic, long-term strategy by investing the minds of the world's young.

Brenda Musilli is just the sort of no-nonsense executive who has helped build Intel Corp. into the world's largest computer chip company. A 30-year Intel veteran, she's done stints in marketing, finance and other corners of the corporation.

And she has a swift no-nonsense answer if you ask her what will be one of the themes at Intel as the company works its way through the current global economic crisis: It's got to keep up its support for education both in the U.S. and abroad.

"These kinds of investments are about remaining competitive as a company," says Musilli, president of the not-for-profit Intel Foundation, which was founded in 1988 and devotes more than half its resources to supporting education efforts in the U.S. and overseas.

Yet even the best-intentioned programs in education face some thorny challenges. On the top of the list: high-technology companies figure their future workers will need a complex set of skills that go far beyond the classic reading, writing and 'rithmatic. But U.S. public schools are still wrestling with how to deliver even those basic requirements--and under the Bush Administration, they face severe penalties if they do not raise their standardized test scores in those subjects. The concern within educational circles is that schools are becoming obsessed with test-taking at the expense of teaching more flexible critical thinking skills.

Those pressures are likely to become even more extreme as school budgets grow more pinched in a chilling economy.

Musilli points out that Intel has supported education since its days as a start-up and that its leaders--starting with Chairman Craig Barrett and Chief Executive Paul Otellini--are deeply supportive of education initiatives.

See "Intel's Chairman On Innovation."

About 10 years ago, Intel dramatically stepped up its education programs. It now values its annual support for education programs supporting math, science and technology at $100 million, a combination of cash grants, equipment and services. (Although we only published the top 10, Intel would have ranked 13 on our list of the most generous corporations in terms of total cash donations.)

When Intel went through layoffs in 2006, the foundation scrutinized its programs, too. "We looked at how we could scale more efficiently and at which programs were getting the biggest impact," Musilli recalls. But the $100 million commitment--about 1% of its fiscal 2007 operating income of $8.2 billion--stayed steady, she says.

That support goes into a host of education programs, both ones aimed at grabbing headline attention and ones providing more subtle backstage efforts.

In 1999, Intel took over the grandfather of all science fairs--the now 66-year-old "Science Talent Search" contest, which attracts something like 1,600 entries each year from U.S. high school students and a similar program internationally that attracts another 65,000 students around the world. The programs aim to make student scientists into heroes--a sort of "American Idol" for the geek set. The financial awards are significant, too: The winner gets a $100,000 scholarship and, each year, the top 40 U.S. winners split prizes that together are worth $1.25 million.

Additionally, Intel annually awards prizes to schools that demonstrate strong science and math programs. In September, Intel lauded Sojourner Elementary School, a 170-student magnet elementary school in Milwaukie, Ore., as a "star innovator." (Sojourner will share cash and prizes worth about $1 million with five other finalist schools.)

There are also fun programs, such as a constellation of more than 100 "computer clubhouses" that Intel sponsors around the world. (Two-thirds of those are in the U.S.)

But Intel's also counting on its behind-the-scenes efforts to pay big future returns. Since 1999, it has offered workshops on how to use technology in the classroom for teachers of grades K through 12. Originally, then-Chief Executive Barrett set a goal of training "100,000 teachers in 1,000 days."

But no company understands how to scale projects better than the computer chip giant. By developing workshops that train senior trainers to teach "master" teachers, who then convey those lessons back to teachers at local schools, Intel estimates that its program has now touched 5.5 million teachers in 40 countries.

"We don't charge for it; it's not for sale," notes Stephen Andrews, the U.S. manager for the Intel Teach program. The programs are technology "agnostic." "We provide the professional development that teachers need, no matter if they're using Macintosh computers or PCs. It's all about the subjects and [grade-levels]," Andrews says. Local school districts have to put support into the programs, too, by giving teachers time off to take the programs and encouraging technology use.

But then there are those standardized tests.

Driven by the Bush Administration's No Child Left Behind program, which demands increases in test scores at the risk of withholding funding, schools have become obsessed with tests, even spending scarce funds and school hours to practice test taking and working on skills such as "bubbling"--properly coloring circles on multiple choice tests forms.

By contrast, high-technology companies are strong advocates of developing what they call "21st century skills," namely the skills and knowledge that they feel will be needed in the coming years. These involve improved communicating and thinking skills, problem solving skills, creativity and "self-direction" skills.

Intel tries to dance between those two demands, using its funding to help schools with the basics while steadily emphasizing the skills that its executives feel will be essential in the future. It has poured significant efforts into coming up with its own metrics for grading the success of its programs, contracting with outside organizations to assess and monitor its programs. "We believe the metrics and evaluation of the program are critically important," Musilli says.

Intel's assessors look at whether teachers who have gone through its workshops are working more collaboratively with other teachers, using technology to advance the curriculum in interesting ways and are engaging the minds of their students.

"But no, it's not directly correlated to test scores," Musilli concedes. "If you believe the research that talks about why the 21st century skills are so important, then one would hope those skills would lead to improved test scores," she says.

And that classic, long-term investment strategy may be one of Intel's greatest gifts to U.S. schools.

Column: Darwin In Your Palm

Forbes.com


Letter From Silicon Valley


Burlingame, Calif. -Talk about watching evolution in process.

A bevy of new devices are emerging, machines smaller than a laptop computer, bigger than a cellphone. Like variations of Darwin's finches, each of these is evolving its own specialty:

--Steve Jobs' iPhone will let you talk.

--"Mobile PCs," based on Intel's chips, will let you run the software written for PC on lightweight, portable machines.

--The "Foleo," Palm's new machine created by Palm Pilot and Treo inventor Jeff Hawkins, aims to be a "mobile companion" that sits somewhere between a PDA and a full-fledged laptop.

Each of these design efforts--and I'm sure there are scores more--are scratching away at the environment, trying to figure out what it will take to survive. What will consumers (and businesses) buy? At what price? With what usage caveats?

No one better channels consumers' longing to be cool than Steve Jobs and Apple. In the business world, Palm's Jeff Hawkins is Jobs' separated-at-birth twin: Twice before, Hawkins has proven that he can translate our hazy desires to break free of our desks into silicon and plastic.

(Full disclosure: This week, Elevation Partners, which owns a portion of Forbes, said it was investing in Palm. Fuller disclosure: Elevation didn't whisper a word about the deal to us before it was announced. Darn.)

But what gives me absolute confidence that something like these devices will exist are not just these electronic artists--but the armies of unrecognized design and manufacturing engineers who are steadily building the silicon chips that will power these emerging devices.

Take Intel: Executives there say that they believe the company's future lies with "system on chips," effectively special-purpose microprocessors tuned to carry out specific tasks.

Even more experienced in this area is Texas Instruments. I didn't include TI in my list at the top because TI's chips are used in such a diversity of cellphones and handheld machines. For a decade or so, Texas Instruments has been steadily building an entire ecosystem of design around its platforms. Constellations of companies in India, China and elsewhere are building special-purpose chips on top of TI's design architecture.

Bottom line: If you can dream it up, somebody can make a chip that will make it work.

Fundamental to this equation are the "foundries," the massive chip manufacturing facilities run by companies as diverse as Taiwan's TSMC, China's SMIC and Chartered, even IBM. Chip fabs have been around for decades, of course. But what's different now is the ease with which they can make literally hundreds of different products at once.

Enormously complex manufacturing software--go ahead, call it artificial intelligence software--mean that these factories can be programmed to stamp out very diverse designs. Relatively small batches of design suddenly have inherited many of the cost advantages that once blessed a single design.

Are you old enough to remember the heyday of Xerox PARC, when it was an incubator for astonishing ideas? The guiding design philosophy of those days, as I recall, was simple: Do away with a constraint. Pretend that a key--but expensive--component has become free. Pretend bandwidth is free. Pretend silicon is free.

Silicon chips are almost free. The limitation now is software. Jobs, Hawkins and for that matter, companies like Intel, must all be scrambling to figure out how to inspire software designers to write applications that will make their devices sing.

Prepare to see scores and scores of devices. That much is clear. The billion dollar question in the balance is one of evolution: Which one--or ones--will dominate?

I'm starting to morph this column into more of a blog-like conversation rather than a classic piece of reporting. Your comments are most welcome; you can send me a note at ecorcoran@forbes.com. If you do, please let me know if I can share your comments with readers.

Column: Running Intel's Numbers

Forbes.com


Letter From Silicon Valley

Numbers are the lifeblood of Intel. Here are some of the numbers that can make--or break--the company, including how many bits of data its chips can crunch, the power those chips demand and exactly how much it costs to make each chip.

My recent story on Intel described the struggles within the company to get performance and power numbers right and the pain of trimming the costs of running the entire business. So far, Intel has cut staff, most significantly in marketing and management. But Intel's executives have more controls at their disposal, and how they tune those dials can be a strong indication of the health of the business today and over the year to come.

Those controls are buried deep in the intricacies of chip manufacturing. A neighbor of mine joined Intel in 1974. She remembers working in its first factory in Santa Clara, Calif., using scissors to cut circuit patterns into "rubies," sheets of red plastic. After she finished, others would take those ruby "masks" and shine light through them, exposing the surface of a silicon wafer covered with light-sensitive goop called a photoresist.

The chemicals hardened, forming a protective cover for the silicon. Then the silicon wafer was bathed in an acid bath to "etch," or dissolve, unwanted portions. Coat, expose, etch, rinse and repeat. The process would go on until the silicon was fully patterned with the electronic design.

I thought of my neighbor a few months ago when I visited one of Intel's finest "fabs" in Chandler, Ariz. The process is still called "lithography," but it bears as much resemblance to the work of 30 years ago as a robin does to a dinosaur.

The Chandler fab is an enormous squat building. Although it is staffed night and day by people, sturdy robotic boxes with an equally sturdy name ("Front-operating universal pods," or "FOUPs") run the show.

No person--even one suited up in one of Intel's stylishly androgynous "bunny" suits--ever touches a wafer. Instead, stacks of 25 wafers are encased in plastic cassettes. FOUPs, which travel along narrow gauge tracks in the ceiling, shuttle the cassettes from one stop to the next: to a machine that smears photoresist chemicals onto the wafers, or maybe to a machine that exposes them to ultraviolet light.

Coat, expose, etch, rinse and repeat. Some of the machines are so massive they require special bolts so that the floor beneath them will not buckle. All cost millions--even tens of millions--of dollars apiece. After about 60 days, the cassettes will have finished their Disneyland-like odyssey through the fab. They will have covered about 32 miles in their FOUPs. And then they will be shipped to another factory, where they will be sliced into individual chips and assembled into boards or modules for customers.

By the end of this year, Intel will be able to make chips with components measuring 45 nanometers wide. That size means designers can squeeze more than several hundred million onto a silicon chip smaller than a postage stamp. By contrast, Intel's 8080 microprocessor, introduced in 1974, had 4,500 transistors connected by circuit lines measuring six microns wide.

As the transistors get smaller, the silicon wafers are getting bigger. Today's top of the line silicon wafers measure 12 inches across; their immediate predecessors were a mere 8 inches in diameter. Thanks to the magic geometry of circles, the larger wafers have twice the surface area of the smaller ones. Better manufacturing techniques mean Intel has to use less energy and water to pattern the big guys.

Bottom line: It costs Intel less (in variable costs) to crank out chips in its latest and greatest fabs than it does in older ones. By next year, four of those 12-inch wafer fabs will be equipped to make chips with components measuring 45 nanometers.

The more chips Intel can build in its new fabs, the better its profits.

Or turn it around: Getting rid of some of its older fabs will perk up the bottom line.

Right now, Intel has a stable of 16 fabs operating or under construction, half of which can handle the big 12-inch wafers; the other half process smaller 8-inch disks. Five of those older fabs are in the U.S.

Intel has already put a Colorado fab up for sale and said it would cut the workforce at a New Mexico site by about 1,000 employees. Intel also recently said it would fold its assets for building a type of Flash memory into an independent company, formed jointly with STMicroelectronics.

That leaves five older fabs, including an operation in hometown Santa Clara.

In past years, Intel has converted older fabs so they can make smaller chips or work with larger wafers. But it's a numbers game: Since larger wafers can produce so many more chips, how many factories does a company really need?

Here's my bet: Between now and the end of the year, we'll see Intel sell off some of those older 200-millimeter fabs. Even the Santa Clara location could be on the block.

When that happens, you can expect to see the bottom line benefit--profitability will improve for at least a couple of quarters.

Once the endorphins of selling assets wear off, management will be left with the toughest task of all: growing the business.

With this contribution, I'm starting to morph this column into more of a blog-like conversation rather than a classic piece of reporting. Your comments are most welcome; you can send me a note at ecorcoran@forbes.com. If you do, please let me know if I can share your comments with readers.

FORBES: Intel Plots A Comeback

Forbes.com

Intel's boss was raised on the inside. Now he must turn it inside out.

Intel Corp. was mired in misery early last year. After two decades dominating the microchip market-- one of the fastest-moving and most unforgiving businesses in the world--Intel seemed lethargic, lagging and stumble-prone. Big layoffs were imminent. Its stock price, having reached $75 in the fall of 2000, had stalled in the $20 range. Net income topped $10 billion in 2000 but had fallen to only half that in the years since. Worse, Intel was getting bested, badly, by a pesky producer one-sixth its size. After years as an also-ran Advanced Micro Devices in 2003 had upstaged Intel's muscle-bound chips, namely Itanium and Pentium 4, Intel's centerpiece. Big customers--IBM, Hewlett-Packard and, eventually, Dell--began turning to AMD. In 2005 Intel lost 2.6 points of market share, far more than it had expected.

Moreover, forays for new growth were fizzling: A big move into new chips for cell phones flopped; a plan to create a business running server farms for corporate clients faded; a billion-dollar gamble on Itanium, a new-generation chip for big servers, failed to pay off. The efforts had been plotted by Craig Barrett, the materials-science engineer who in 1998 succeeded Andrew S. Grove, the salty leader who had helped start the company. Barrett was helped by a successor of his own: Paul S. Otellini, an Intel lifer who in mid-2005 became the first non-Ph.D. to run Intel.

Unaccustomed to losing, Intel's ranks pelted their new chief with bitter e-mails: Intel had lost it; management was incompetent. Some likened Intel to a lumbering Detroit carmaker. Today Otellini, 56, is reluctant to talk about the backlash, though his chagrin is apparent. His de facto number two, Sean Maloney, is more blunt: "It was a swift kick in the gut. We were angry and disappointed in ourselves." He adds: "We just had a visceral emotion: We're gonna fix it."

That frustration pushed Otellini to wage the most sweeping overhaul at Intel in 20 years. Gone are plans for diversifying away from Intel's chips. Gone is 10% of its workforce. Otellini also bailed Intel out of cell phones, selling off the XScale mobile-chip line. In a first for the company, he has put one chip factory--so far--up for sale. And Otellini is reorienting Intel's focus to look beyond its slow-growth mainstay, processor chips for desktops, to what he hopes will be the Next Wave. This is a world of lightweight notebook PCs and a gaggle of ultramobile machines smaller than a laptop but bigger than a BlackBerry. "The PC market has been very good to us. It's near 300 million units [a year]. It's going to grow to 500 million units," he says. "But how do we sell a billion of something? Can we create a multihundred-million-unit market, per year, in handhelds?"

Intel already had in place a growth engine that could fuel its comeback: Centrino, simpler, faster and cheaper than the Pentium 4. The design began with Intel engineers in Haifa, Israel, far from Silicon Valley. Centrino would power notebook computers--but the "core" processor at Centrino's heart would become the inspiration for all of Intel and lead to a starkly different design than the Pentium, which had reigned since 1993.

In Silicon Valley Intel engineers thrived on using every available transistor to get more speed and power from a chip. The adverse side effect: lots of waste heat. The 178 million transistors in Intel's top Pentium 4 give off enough heat to fry an egg.

In the new-gadget era envisioned by Otellini the chips must be the antithesis of a hefty Pentium--sleeker, simpler, far cheaper and, above all, cooler. Lash a couple of processor cores together and bundle in specialized parts for, say, wireless linkups or video graphics, and this system can power everything from a palmtop to a server. Intel says a new family of cores, aimed at mobile devices, will be ready next year.

"How do we fit inside of something that sells for $100 and make some money?" Otellini says. "Costs become essential. Architecture becomes essential. Integration becomes essential. And the culture of the company has to wrap itself around that." This threatens "the ego of the Intel engineering community," says Maloney, executive vice president. "Their whole notion of self-worth was based around bigger and faster. That aspiration needed to change to cooler, sleeker, smaller. That's a big deal."

Thus Intel has abandoned what may be the most prodigious platform--the cell phone, with 1 billion units sold last year, four times the number of PCs--in favor of a new gadget that barely exists. Succeeding requires Intel to do two things it never has done particularly well: make chips at the lowest cost possible and let customers' demands shape development.

The Intel of old held 85% of the PC microprocessor market and routinely dictated upgrades and designs with little input from the clientele. AMD Chief Hector Ruiz tacitly goads Intel for this: "We did something that, unfortunately, is all too rare in the semiconductor industry--we went out and talked with [customers] about what [they] needed," he said in an industry speech in October 2006.

The new Intel must undergo a personality transplant. The Intel that Andy Grove built had enshrined sharp confrontation as constructive engagement, in the imperious and emphatic style of its chairman, for whom decisions were crisp, choices were binary and markets were won or lost.

Otellini, who scoffs privately at the "cult" that can surround a company's founders, can deliberate something to death. He deploys a reserved manner and prefers persuasion over fiats, consensus over combat. Frustration or embarrassment shows in a red flush to his face. His equanimity is a mixed blessing. It can be seen as indecisiveness.

He was born and bred in San Francisco, and during his college years he spent a summer working with his father, a butcher, in a slaughterhouse. ("I think he did that on purpose, because he didn't want me to ever think of that as a career," Otellini has said.) He attended the University of San Francisco, and in 1974 he landed his M.B.A. at the University of California, Berkeley, joining Intel as an analyst. He hasn't missed an Intel paycheck since. He rose in marketing and management--"I'm a product guy"--and spent a year in 1990 as an aide to Grove.

Barrett succeeded Grove in 1998 and began looking beyond microprocessors, a business he derided as a "creosote bush." (In the desert a creosote bush poisons the ground around it to ward off other vegetation.) He had Intel spend $10 billion buying communications and networking firms, even as it invested hundreds of millions more in the Itanium chip project with HP.

By 2002 the dot-com crash and the collapse of telecom had devastated Intel's profits and chilled Barrett's plans. Intel's move into chips for mobile phones had become a quagmire. Although the company had grabbed a promising chip line in a legal settlement with the old Digital Equipment in 1998 and renamed it XScale, the chip wasn't enough. Unlike the PC world, software for such chips was patchy. Even making the chips proved more costly than expected as Intel had to rejigger manufacturing processes.

"In hindsight, phones--even the smart phones we targeted--was not an area in which we had 20 or 30 years of expertise," says Otellini, who became president in early 2002. "It didn't play to any of our strengths. We didn't have the software or the architecture." Nor did Intel have many customers. Research In Motion put XScale into its BlackBerry, but cell phone makers were leery of Intel's reputation in PCs for reaping most of the profits and leaving boxmakers with less. "There were entrenched players, many of whom had seen the PC movie," Otellini says.

Meanwhile Intel was getting into trouble in microprocessors. The Itanium, in gestation since 1994 and a few years behind schedule, faltered when customers balked at the hassle and the cost of rewriting old Intel-based software for the new chip. Worse, the Pentium 4 was a hothead and a power guzzler, at a time when corporate customers eyed even electricity bills in a bid to reduce their tech spending.

AMD, Intel's plucky rival, was poised to benefit. Its engineers had been working on a homegrown chip that rivaled Intel's high-end Itanium for power but easily ran existing software. And it was cool--generating less heat than Intel's big chips. AMD debuted its Opteron for high-end servers in April 2003 and rocked Intel's world. The competition would knock the average selling price for high-end chips from more than $600 apiece in 2003 to half of that today, says IDC analyst Shane Rau.

Intel, meanwhile, had glitches. It canceled one new version of Pentium 4, ran a year late on another, delayed several other products and ran short of chips because of bad forecasting. Only the transition of the chief executive job from Barrett to Otellini, in May 2005, went smoothly. Intel stock rose 8% in calendar 2005; AMD's rose 43%.

Then Intel stumbled in a spectacular way: It missed sales forecasts on Wall Street two quarters in a row, through the first quarter of 2006. And Intel was bloated. In 2000 it had 86,000 people producing $34 billion of revenue; by 2006 it had added 17,000, though the top line had grown only 5%.

Otellini spent much of last year handling the fallout--disillusioned employees, the board demanding to know why Intel had slipped so badly, a huge round of layoffs. Yet Intel already had a key element in place for a dramatic comeback--the processor core inside Centrino.

In 2000 Otellini, then head of Intel's microprocessor business, had realized slim notebooks would need a cooler, less power-hungry processor than the Pentium 4. So he set engineers in Israel to the task. They approached it in a non-Intel way, sacrificing some raw power to get a chip that ran cooler. The idea was scorned inside Intel. "The company had been so successful in the 1990s it was hard to talk about doing things differently," says David Perlmutter, who led the project. "It was easier to be remote and question the basic religion of the company."

In 2002 their work was all but finished, when Otellini had an epiphany: Notebooks and laptops had to be able to connect wirelessly to the Internet. So Otellini decreed that the new chip should wait until the engineers could fuse their core to a homegrown Wi-Fi component. "Making that decision was tumultuous inside of Intel, to say the least," he says. "It was a cultural issue. We're a microprocessor company." The Intel faithful disliked delaying a new chip to wait for adjunct technology. One computer maker jeered at the project, calling it "Latrino."

Intel rolled out its Wi-Fi-ready Centrino in March 2003. Six months later the new chip was a much-needed hit. Intel's Perlmutter was convinced he could see the next horizon. "The first Centrino wasn't bad," he says. "But could we evolve the architecture to be better than the Pentium 4?"


It could. A Centrino-like core was anointed as Intel's flagship for notebook and desktop PCs. In October 2004 Otellini canceled future Pentium 4 efforts. He signed on for a big test of whether Intel's engineers could shed their dictatorial ways to work closely with a most demanding customer: Steve Jobs of Apple.

After much wooing by Otellini, Jobs had agreed to consider using the next core, so long as Apple engineers could work hand in hand with Intel's designers. And in mid-2005 Jobs took the stage at his annual powwow with developers to announce that the Apple Macintosh would start using Intel chips. Since the Mac's debut in 1984, it always had run on chips from Motorola and its partners. Otellini gets coy when asked whether Intel might eventually surface in the Apple iPhone, due in June.

In spite of Centrino's success, Intel overall was sagging. Early last year Otellini hired consultants from Bain & Co., who huddled with some of Intel's smartest managers to take a snapshot of the company. Their report, two months later, stung Otellini and staff: Intel was fat and inefficient, hampered by high costs and a swollen marketing department. One example: Intel had too many "two-in-a-box" managers (a pair who share title and job). One set even jointly oversaw a staff of one.

"We weren't used to the sniping. No one had questioned us for years," says marketing chief Sean Maloney. But instead of demurring, senior execs focused on a fix. "How could you let Intel fail?" he says. "We're the company that's famous for technological change. The sense of personal shame would be overwhelming."

But Intel stumbled again in launching its rescue mission. Led by the deliberative Otellini, the company imposed job cuts so slowly that the ranks grew ever more angry. Intel first told Wall Street it would analyze the company's structure but didn't cite layoffs. Later it said it would fire a thousand managers. In June 2006 it sold off the xscale mobile chip line to Marvell Technology Group for $600 million, shedding more staff. Only in September did Otellini & Co. put a number on the layoffs: 10,500 jobs, or 10% of the workforce, the biggest cut at Intel since it abandoned the memory-chip business in 1985. More layoffs loom as Intel weighs selling the weakest part of its business making flash memory (used in cell phones and cameras) by year-end.

Now Otellini plies new growth. Intel's sales of various "core" chips (including the Centrino and the "Core 2 Duo" lines, both inspired by that original core approach in Centrino) will exceed sales of its classic design this year. Notebook chips are gaining fast: By 2009 Intel figures it will ship more chips for notebooks than for desktop PCs--happy news because at least for now Intel makes more money on notebooks.

Next: chips for the ultramobile handhelds. These will incorporate, on one piece of silicon, a Centrino-like core plus circuits handling such tasks as Voice over Internet, graphics for games and search. Otellini argues that by 2011 such chips could compete in what he expects will be three newly formed $10-billion-a-year markets--one each in mobile, consumer electronics and supercheap PCs for the Third World. That enhanced core goes for now by the name Silverthorne.

"Silverthorne could really be a thorn in Intel's side," frets Auguste Richard, a senior analyst at First Albany Capital in San Francisco, who nonetheless admires the Intel overhaul and has a "buy" on the stock. Any system-on-a-chip revenues for Intel are a few years away. Wall Street also worries about the inevitably thinner profit margins in chips for cheap palmtops.

Intel never had obsessed over cutting product costs. "You would never have had a discussion with Andy [Grove] or Craig [Barrett] about us being the lowest-cost producer," Otellini says. When a company has products that could command as much as 80% margins, he notes, "costs are important but not critical." But cost will be everything in the handheld market, and Intel is counting on its mind-boggling prowess in manufacturing for an edge.

It makes some of the tiniest chips ever created for a PC, cramming them onto the largest silicon wafers in the world. It now has 5 factories (of a total 16) that use platters 300 millimeters across (12 inches or so). By year-end Intel will produce chips with transistors measuring 45 nanometers (45 billionths of a meter), smaller than most human viruses. That will let it etch 2,500 chips on each 300mm wafer.

Otellini bets Intel can stay so far ahead of rivals that it can make chips as cheaply as any competitor. That includes China, which is emerging as the foundry for the rest of the chip world. "We've been benchmarking them. We don't think we're at a cost disadvantage," he says. In March Intel set plans to build its next chip factory, typically a $4 billion project in the U.S., in Dalian, China.

But Intel will have to prevail over fearsome foes: Samsung and Texas Instruments, established vendors of chips for the picky cell phone business. And Intel's new push will require its engineers and managers to cater to customers in ways they never have before.

"Intel talks about being customer-centric, but it's not in their DNA. They've been brought up to rule the world," says Henri Richard, AMD sales chief. When he meets with phonemakers, they tell him what they want, what a chip should do and how much it should cost. In PCs, "Intel tells the customer: 'This is the way it's going to be.'"

At TI, Senior Vice President R. Gregory Delagi says his company has spent a decade learning to coddle clients. It reorganized its supply chain to have TI products ready just across the street from a customer assembly plant. During the tech slump in 2001 TI built a site for a customer within its own factory in France to let the client's engineers work alongside TI staff.

But Intel execs say they learned how to mollify customers as fussy as Steve Jobs. And they vow that their foray into the ultra- mobile market will fare better than their effort to make chips for cell phones, in part because Intel's cores are heirs to the mountains of software written for the 850 million or so Intel-based computers in the world today.

"That's the heart of why it was important for us to make the changes we made last year," Otellini says. A billion computers now link up to the Internet, most of them Intel-based, and it took 12 years to reach that milestone. The next billion machines will come online in only half as much time--and Intel will have to fight hard for every single one of them.

Q&A: A Talk With Intel Chief Paul Otellini

Forbes.com

(originally published online on 5/17/07 but part of magazine 6/04/07 package)

Excerpts from a Q&A with Paul Otellini, chief executive of Intel.

Forbes: When did you think Intel had to change?

Otellini: My epiphany for driving our strategy came around 2002. We were leading up to the launch of what ultimately became Centrino. I felt very strongly that wireless communications as an integral part of a notebook experience was a killer market opportunity. Six months after launch, it became very obvious that this was a home run.

Around the same time, I changed our planning processes. We had had a microprocessor group, a chip set team, a server group and so on. I said, "We're going to turn this around and identify the end markets and do our planning from the markets backwards." So we changed product planning inside of Intel to be around platforms. It played to our unique advantages--silicon technology, platform architecture knowledge and the ability to scale massively.

Intel had accumulated something like $10 billion acquisitions in communications and networking. Did you have to do that?

There was certainly some communications architecture expertise that we didn't have inside the company. Our work in wi-fi and WiMax came out of those acquisitions. Clearly, one of the larger areas of investment was in the handset division, which we exited. There were a lot of lessons learned there. We saw that there wasn't a way for us to make good money there. But I believe very much that the future of computing is in handheld devices.

But if the future is in handheld devices, why get out of handsets?

It's a lot easier to add voice to a computer than to add computing to a phone. We're not just shrinking the notebook. We're asking, How do we provide a full Internet experience that also includes voice, in a handheld form-factor? I think the Internet is the killer app of mobile computing. Of all computing. The Internet runs on Intel architecture today.

So our view is, if you could deliver the full computer experience, in a handheld form factor, with the right kind of power and performance characteristics, then you have a very interesting product. And in that business, we compete based on our strengths, not our weaknesses.

Is the business model for the ultra-mobile industry going to look like the PC world?

I don't think so. We're not taking the PC business model into this area. We're taking the Intel architecture, which runs most of the Internet, into new devices. These are not going to be $200 chips, inside of a $200 phone. You have to deliver the right kind of performance to run the applications, have the right power envelope to give you the all-day battery power, and the right price to hit the sweet spot for the consumer. That means high integration of technology and moving to very small chips and system-on-chip architectures.

Saying, "I'm going to take a pre-existing architecture on which a billion Internet devices run today and move that into handhelds" is wholly different than saying, "I'm going to take the PC business model and move that into handhelds." It's a whole different model. There's different software to some extent. Windows is a player there but not the only player. And you can see that with Apple emerging.

More and more chip manufacturers have stepped back from manufacturing chips and instead are relying on foundries. What about Intel?

Chip manufacturing gets harder and more expensive all the time. It's basically the laws of physics and the laws of economics at play. To build a modern semiconductor plant which uses 300-millimeter wafers, and state-of-the-art lithography with designs measuring 45 nanometers, costs close to $4 billion. Then there are the tools inside it, which amount to close to a billion dollars, per generation of technology. That means you need to generate $4 billion to $5 billion a year in revenue out of it. There are not many semiconductor companies that are $5 billion or more in revenue. So economics leads many companies to collaborate.

No. 2: The laws of physics mean chip making gets harder and harder. We think we have some breakthrough technology at 45 nanometer. We think it will be harder for people to do that than it was in the past at, say, 65 nanometer or 90 nanometer. Our lead over the competition may extend with this generation and probably extend a lot after that. This is not a macho thing. It's all based on sheer economics.

As the Internet and hopefully our architecture come into the world of consumer electronics and handhelds, the price points are not going to be $1,000 but a few hundred dollars. So we have to be able to get this to low-cost, high performance single chips. And make reasonable profits.

Will Intel work differently with these device makers than it has with PC companies?

Over time, the answer is yes. And what we do in the PC space will change too. As you move towards system on a chip, particularly in ultra-small devices, different customers will have different requirements for what's on the chip. We may have to do derivative versions or semi-custom versions--and create ways customers can exploit their own intellectual property. We do some of this today in packaging. And in some areas of consumer electronics we're building system on chips for certain classes of devices such as set-top box makers.

What about Itanium?

It's used for really big machines: the Tokyo stock exchange, mainframe replacements. There are two models for high-performance computing: scale up and scale out. Itanium is a mainframe scale-up kind of machine. Google, with its zillions of racks of servers, is a scale out. At some point in time, the scale-out model may prevail. But for right now, for some classes of applications, particularly ones for organizations where systems have to be ultra-reliable and high performance, scale up still matters. And Itanium is our best architecture for that today.

What's been your hardest decision?

The one that led to us having to downsize. It was pretty obvious at the analyst meeting last year that we said some of our basic economic models, which had existed for many years, were changing. We had to get leaner, get more focused.

What have you learned by being on the Google board?

Much of the success of Google, apart from obviously their technology, is their aggressive willingness to partner and to make their partners successful. Google says, "You, Mister Partner, and I can create a huge opportunity to monetize assets that you may have. You can do it on your own, or you can do it with me and my scale, and I'll cut you in on it." And that "cutting you in on it" has been the heart of much of Google's growth.

That business model of setting up opportunities where you share mutual success financially has not been a model that has been inside this company or even in the classic PC space. I think this is a very interesting model for us.

Column: Andy Grove's Re-entrance

Forbes.com


Letter From Silicon Valley

12.18.06, 6:00 AM ET
Burlingame, Calif. --Andy Grove understands how to make a re-entrance like no one else.

Not the pop-star flounce onto a stage, heralded with flashing lights and throbbing background music. But the kind of entrance that matters--the ability to look at a growing problem that surrounds him, step away--then come back in with a fresh solution.

I was reminded of this skill recently when the retired Intel chairman joined Harvard Business School professor Richard S. Tedlow onstage recently here in Silicon Valley to discuss Tedlow’s newly published biography, Andy Grove: The Life and Times of an American.

At 70, Grove is still wiry and hip enough to sport a black leather bomber jacket, even though his hands tremble slightly due to Parkinson’s disease. He smirked as Tedlow described how Grove originally told him that the idea of someone writing his biography was the “stupidest idea” he had ever heard. But Grove quickly relented and gave Tedlow his full cooperation.

What comes through in the biography and in the discussion onstage with Tedlow is how Grove made his biggest decisions: by stepping outside himself and viewing the situation coolly, at a distance.

Case in point: a fateful decision in 1985. At the time, Intel was reeling from losses in its memory chip business due to sharp competition from Japanese manufacturers. Grove had spent months wrestling with the problem, including petitioning the U.S. government to take action. Frustrated, he asked Intel co-founder Gordon Moore, "If we got kicked out and the board brought in a new CEO, what do you think he would do?" Moore’s answer: quit making memory chips. "Why shouldn’t you and I walk out the door, come back and do it ourselves?" Grove responded. So they did.

Intel faced an similarly crucial juncture in the early 1990s when Grove had to bet the company on a single chip design direction: Should Intel continue making its x86 class chips or should it follow a more technologically elegant approach called “reduce instruction set computing” or RISC? Intel’s engineers split into warring camps; RISC was the hipper choice, the one that seemed to prove that Intel’s engineers were the best. Grove even took part in a jocular in-house Intel video in which he wore dark sunglasses and rapped about the virtues of RISC chips.

Still, Grove listened when colleagues approached him with a nonengineering-based argument: Abandoning the x86 architecture, they said, would leave Intel’s huge base of existing customers stranded. None of the software written for x86 chips would work smoothly on the newer design. “They saw through all the technical mumbo jumbo,” Grove recalls, “and focused on the most important, basic factors.” Grove stepped away from his own inclination to pick a more technologically sweet solution and stuck with the x86 design. Intel’s value soared.

Grove was slower to step outside his own beliefs when customers discovered a subtle flaw in the ability of Intel’s Pentium processor to carry out certain types of arithmetic functions. Grove dragged his feet on apologizing to customers until the howling both inside and outside of the company was deafening. In his book, Tedlow describes the Pentium gaffe as Grove’s biggest mistake.

Onstage with Tedlow, Grove was impatient with that choice. Yes, a mistake. But his biggest? Grove says he agonizes every day that he didn’t leave Intel with a clearer road map for the future. Intel’s most recent track record has been mixed. Its high-end chip, Itanium, which took root during the end of Grove’s tenure, proved too ambitious and left the company vulnerable to competitor Advanced Micro Devices. Intel is also still seeking a clear path in a world where countless little handheld electronic devices are emerging as the next new thing.

Tedlow countered that Grove was asking too much of himself. “Every generation has to solve the problems it faces,” he told Grove and the audience. “It’s hard to solve the problems that will happen 10 or twenty years out.”

“That attitude brings an anti-investment, pro-short-term perspective,” Grove snapped back. “Some problems take longer than the tenure of a CEO,” he added.

These days, Grove has taken on a couple of other big problems, ones that will certainly take more than a few years to right: improving the U.S. health care system and preserving America’s separation of church and state.

Once again, Grove is trying to step outside his personal concerns to see the problems in a clear light. Almost a third of all Americans lack adequate health care and increasingly turn to hospital emergency rooms for simple medical care--a disaster in the making, worries Grove.

Existing technology can help, he believes. Grove is a fan, for instance, of walk-in medical clinics at drugstores instead of emergency rooms for many procedures. He advocates keeping people’s medical records in PDF files on the Internet to cut costly mistakes and unnecessary procedures. Wireless sensors that kept elderly or infirmed patients in close contact with medical providers could help them stay in their own homes instead of heading to nursing facilities. “We’re using technology to achieve extraordinary care for a few people. What intrigues and motivates me is the idea of using mass technology to help many more,” he says.

Just as important, Grove believes, is protecting the U.S. from the kind of sectarian strife that has ravaged so many other countries, including his native Hungary, where he saw relatives suffer first at the hands of the Nazis and later under the Communists. A clear separation of church and state--as set forth in the U.S. Bill of Rights--is essential for creating an environment in which people can believe what they choose and tolerate differences among their neighbors. Grove is supporting an online petition drive calling for the renewed separation of church and state.

Stepping outside your own concerns and pride, finding a new solution and then reentering is tough for any of us. It’s far easier to pontificate on other people’s problems than to see our own clearly. But as Grove has shown, true self-awareness can be our most valuable asset.

Andy Grove: Life and Times of an American

By Richard S. Tedlow

PORTFOLIO/PENGUIN; 568 Pages; $29.95

Over the past few decades, we've seen a parade of business archetypes: There's been the chief executive as stubborn rebel, as domineering whirlwind, as greedy crook. Now in "Andy Grove: The Life and Times of an American," Harvard Business School Professor Richard S. Tedlow takes us backstage to see the human jitters, foibles and strengths of a legendary boss.

Grove deserves a big biography. As much as any other single person, he built Silicon Valley, bringing the computer revolution into all our lives. He led Intel Corp. to supremacy in the microchip business, enabling powerful computers that are cheap enough to be birthday presents for many people.

Tedlow, who had unfettered access to Grove, goes well beyond the career highlights to present a warm and discursive portrait of a complex man. Grove is unfailingly blunt, quick to engage in sharp confrontation, wickedly funny, brilliant, a thoughtful listener, plagued by fear, achingly critical of himself and others and, at times, simply wrong. What come through most steadily: Grove's insatiable hunger to learn -- and his burning desire to be noticed.

Grove's story has the lyrical qualities of a Broadway show. Born Jewish in Hungary in 1936, Grove fled to the United States when the Soviets invaded Budapest in 1956, earned a doctorate in chemical engineering and became a captain of industry. Along the way, he has confronted some formidable health challenges: scarlet fever as a child, prostate cancer in his late 50s and now Parkinson's disease.

On the job, Grove was beset with doubt from Intel's first day. When he joined in 1968, "I was scared to death," Grove later said. "I literally had nightmares. I was supposed to be director of engineering, but there were so few of us that they made me director of operations. My first assignment was to get a post office box so we could get literature describing the equipment we couldn't afford to buy."

Even so, Grove had the ability to step outside his daily tussle and see himself -- often wryly -- at a distance. In 1969, Grove pasted into his notebook a magazine clipping that described the responsibilities of a motion picture director: "a soother of egos, a cajoler of artistic talent ... [with] the vision and force to make all these elements fuse into an inspired whole." Above the clipping, Grove printed: "MY JOB DESCRIPTION?"

His devotion to Gordon Moore, Intel's co-founder, bordered on filial. When Moore was away from Intel during his time as chief executive, Grove wrote memos to fill in what Moore had missed. In June 1975, Grove wrote: "Welcome home! You absolutely, literally, positively could not have chosen a better/(worse) week (depending on point of view) to be gone."

Grove was much more terse with Intel's co-founder, Robert Noyce, a charismatic leader and gifted scientist who was uninterested in daily management, according to several accounts. "I view the ... situation as Intel's biggest management blunder, with you being the principal," Grove wrote to Noyce in 1971. "I think you should also have to face [your mistakes] like the rest of us have to otherwise you will keep going on making them!"

Such raw comments -- what Grove liked to call "constructive confrontation" -- became a trademark. Yet Grove routinely gave himself a sharp tongue-lashing, too. In November 1976, Grove wrote: "[D]issatisfied w/overall co. performance (hence: me!) ... frequently depressed; thoughts of bailing out."

"Reinvention" has been so overused that it now has the resonance of a sitcom theme song. But Tedlow describes how Grove saw himself as a student at many junctures of his career and refreshed his skills with the same tenacity Intel applied to designing each new generation of computer chips.

Grove held his standards high, sometimes achingly so. Colleague Sean Maloney recalled devoting more than a month to a piece of analysis only to have Grove return it, saying, "I'm bitterly disappointed."

For some, such critiques cut to the bone; others, including Maloney (who is now among Intel's top executives), took it as a goad to excellence. "He would get the best of every individual," Maloney told Tedlow. "He may piss them off, which he frequently did, but he got the best out of [them]."

Tedlow's book veers closer to an appreciation of Grove than to a hard-hitting critique. He concedes as much in his acknowledgements, noting, "the reader should be aware that Andy Grove is a magnetic man. It is impossible, at least for me, to have spent as much time with him as I did and to have immersed myself as completely as I have in this project without developing feelings of admiration and affection that must have colored this account to some degree."

More insight into Grove's jousts with Microsoft founder Bill Gates would have been welcome. Tedlow devotes the bulk of one chapter to the topic but didn't interview Gates. That's a pity.

So many successful people become consumed by vanity or arrogance. Grove certainly wanted to be recognized for his accomplishments. Yet no matter how many times he reinvented himself, he never quite shook the traces of the boy who once hid from the Nazis. His lifelong belief that disaster lurks just around the corner became his constant goad, his strength, his humanity -- and makes for a story well worth telling.

Silicon Always Wins

Teaching silicon new photonic tricks promises a huge boost in getting data out of a computer


In his lab at Sun Microsystems' San Diego Physical Sciences Center, Ashok Krishnamoorthy is surrounded by big numbers: looming powerful computers that can crank through a trillion operations per second. But what commands his attention these days is something very small: a prototype silicon chip, only a few millimeters on a side, that works like a magic gateway between muscle-bound computers.

Although still a hatchling, this so-called silicon photonic chip, devised by a Carlsbad, Calif. startup called Luxtera, could mark the beginning of a new Internet era when computers will be able to tap into huge reserves of data, no matter where they are situated, as easily as they now retrieve data from their own hard drives. "It will mean that distance truly won't matter anymore," says Arno Penzias, a Nobel laureate and one of Luxtera's venture backers. "Wherever you are, you can share in all the world's information."

Big promises come in small packages. Luxtera's chip is neatly hidden inside a component that looks like a gold-covered mint wafer. Metal pins along three sides both secure the piece to a circuit board and deliver streams of bits to the silicon device. On the fourth side of the component is a plug that resembles a telephone jack. Krishnamoorthy slides a bundle of fiber-optic threads into the plug. One thread is attached to a laser.

As the pins deliver bits sent from another computer, the laser pumps a steady stream of light into the chip. Inside, a modulator works like a tiny shutter, imprinting the bits onto the incoming laser light. The light signals do a victory lap in the device, then head out on a path that runs parallel to the one they came in on. The signals spill onto an optical fiber, then travel another 20 meters before reaching a detector, a chip that transforms the light signals back into electrical ones. "We've been working with Luxtera for almost a year now," says Krishnamoorthy. "I have personally tested the modulators to 10 gigabits a second." That's fast enough to send a DVD movie in four seconds.

Silicon photonics aims to solve what has become one of the huge bottlenecks in the information age, the movement of data in and out of computers. For the past 40 years computer chips have grown faster as designers have marched steadily to the drumbeat of Moore's Law, roughly doubling the number of transistors on a swatch of silicon every two years. By shortening the distance electrons travel, they've made chips go faster. But like an automobile pulling out of the driveway, electrons that venture outside a chip must follow some path--usually copper--to reach their next destination. Intel's top-of-the-line Pentium 4 runs at 3.7 gigahertz and relies on a souped-up "bus" that is about a quarter of that speed.

Designers have invented clever shortcuts for electrons, like Sun's recent approach for nudging separate chips closer together and zapping data between them. But radically improved performance calls for the use of photons, or particles of light, which are 250,000 times lighter than electrons and can fly in close formation, squeezing lots of data into a small space. Telephone companies spent the 1990s ripping out copper lines and replacing them with optical fiber and expensive networking gear to turn digital signals into light waves. This was never a cheap trick, though, depending on compound semiconductors such as indium phosphide and gallium arsenide, which don't enjoy the mass-manufacturing economies of silicon, the mainstay of the computing universe.

"Silicon always wins," points out Cary Gunn, a cofounder and vice president of Luxtera. If optical devices could be built in silicon, the cost of communicating data would fall.

Silicon is finicky about light. Tickle compound semiconductors with enough electrons and they spit back photons (the telecom industry uses them for its optical magic). In the 1980s Eli Yablonovitch, now a professor at UCLA, invented something called photonic crystals, which manipulate light much like transistors shuffle electrons around. Key to building useful photonic crystals, however, was carving tiny structures into semiconductors.

In the late 1990s, after nine years in the Air Force, Gunn wound up in graduate school at the California Institute of Technology working with Axel Scherer, one of the world's experts in building very tiny electronic and photonic structures. By then the enormous manufacturing muscle of the silicon chip industry had pushed the size of key chip components down to roughly 100 nanometers--a quarter of the wavelength of infrared light, which is widely used by the telecom industry. Only at these tiny dimensions can engineers manipulate the electrons buzzing within silicon to change its photonic properties. "That turned the corner," says Yablonovitch, who cofounded Luxtera with Gunn and Scherer. The challenge was to train silicon to modulate laser light fast enough to keep up with the data pouring in from computers.

Scores of inventions had to fall into place. (All told, Luxtera has filed for more than 75 patents; 15 have been issued so far.) The central idea of the modulator depends on the fact that light travels at different speeds through different materials. (Put a pencil in a glass of water and the pencil looks bent because light travels more slowly through water than through air.) Light traveling through silicon usually moves only a third as fast as it would in a vacuum. At the nanoscale level, Luxtera engineers figured out how to tune silicon by applying voltage and thus make light move more sluggishly.

Within the Luxtera chip, light is split along two paths, and the twin beams are nudged out of synch with each other by the modulator, acting upon incoming data. When the beams recombine, they either make a bigger wave or cancel each other out. This way the modulator stamps data onto the light.

Figuring out how to funnel as much light as possible from a laser into the tiny modulator structure is another part of Luxtera's secret sauce. The company also saved enormous trial-and-error time by using a complex modeling program built by two Caltech undergraduates that simulates how light and electrons interact in three dimensions. (They sold it to Luxtera in exchange for founder's equity.)

The timing of the telecom bust helped, too. In November 2001 Luxtera's venture capitalist tapped chip industry veterans, including Alexander Dickinson, who got his start with optical devices at Bell Labs. Minutes after Dickinson signed the papers that gave Luxtera $7 million in seed capital, Gunn bought $2 million worth of test equipment for $200,000 in a fire-sale auction at Nortel. Since then Luxtera has raised another $24 million in venture funding.

That 10 gigabits a second is only a starting point, says Dickinson. Adding light signals of different wavelengths, like creating extra channels, will multiply performance. Shrinking component sizes will also speed the modulator.

Intel researchers are working feverishly on their own silicon photonic components, including modulators, which operate at 4 gigabits a second. Those could be commercial devices by the end of the decade. Last December the Defense Advanced Research Projects Agency kicked off a four-year program to build integrated electronic-photonic devices. "This is potentially a very disruptive technology," says Jagdeep Shah, who manages the Darpa program. "We're sort of like at the early stage of integrated circuits."

Essential to holding down costs is using the same manufacturing tools and factories used to make cheap PC chips. Luxtera is relying on Freescale Semiconductor to build its chips, and in the past 12 months Freescale has been sliding Luxtera's designs right into the standard manufacturing line for the PowerPC chips that go into a range of devices, including Apple computers. David Mothersole, chief technology officer of Freescale's networking business, expects to be making samples for Luxtera's first customers by the end of this year. Although the startup plans to make money by selling its chips to computer systems manufacturers, its director of marketing, Gabriele Sartori, is a staunch advocate of spreading the new technology through licensing.

Luxtera's growing fan club also includes Michael Fister, formerly with Intel and now chief executive of Cadence Design Systems, the leading maker of chip-design software tools. "Demand for high-speed interconnects is strong," he says. "There's good reason to be intrigued with this technology, and Luxtera is definitely worth watching."

Lighten Up

Luxtera's chip speeds data out of another chip by printing electrical signals on light waves. Here's how it works:Laser light is fed through tiny waveguides and split into two silicon channels. Meanwhile, a stream of bits from a microprocessor is fed into an electronic driver, which applies voltages to the silicon corresponding to the bits, changing the phase of the light. The two waves recombine to form distinctive peaks and valleys. The light can travel any distance via fiber-optic cables and then be converted back into electronic signals.

FORBES: I Opt for Opteron

I Opt for Opteron; Scrappy AMD has finally trumped Intel, for now
--Scrappy AMD has finally trumped Intel, for now

by Elizabeth Corcoran
and Quentin Hardy

Volume 173 Issue 5

For the first time in decades perennial underdog Advanced Micro Devices has one-upped the chip king, Intel Corp. One of AMD's latest microprocessors, Opteron, is winning over loyal Intel customers, and Intel has now conceded it must match it. Just how seriously Intel miscalculated the needs of business customers became clear in late February when HP, Intel's longtime partner and a codeveloper of its top-of-the-line Itanium chip, said that it would begin using Opteron as well as Intel chips in its low-end and midrange servers.

The HP announcement followed similar declarations by the likes of Sun Microsystems, IBM and Fujitsu Siemens--in fact, virtually all the big computer makers except Dell have opted for the 64-bit Opteron. Says Richard Marcello, HP's senior vice president of business-critical servers, "The fundamental reason we picked Opteron right now is that the overall performance is very good."

In the year since Opteron's arrival, AMD has come from nowhere to become a contender in business computing. Sunnyvale, Calif.-based AMD has at least another few months to gallop unchallenged through the selling fields. Intel Chief Executive Craig Barrett has said his Opteron-beater won't be ready until midyear. Quips Hector Ruiz, AMD's chief executive: "We are happy that our competitor sees the advantages of AMD64 and has decided to try and adopt a similar strategy."

Right now AMD's share of the $11 billion market for chips that power midrange servers is tiny, says analyst Nathan Brookwood with Insight 64 in Saratoga, Calif. The company could capture $680 million in sales this year and up to $2 billion in 2005, with juicy 80% gross margins, he says. AMD needs the boost. In fiscal 2003 it lost $274 million on sales of $3.5 billion.

Sacrificing a billion dollars to AMD is a flesh wound for Intel, which grossed $30 billion last year. But the psychic gash is deep. Opteron doubles, from 32 in the last generation, the number of bits that a microprocessor handles at one time. As a result it increases, from 4 billion bytes to a number 4 billion times as large, the amount of memory that can be used by software running on the chip. Intel spent a decade and, by at least one estimate, more than $1 billion developing the Itanium, its own 64-bit chip, but has had trouble getting customers to use it.

Intel's tactical blunder was in breaking with its tradition of designing chips to run old software. "Intel thought that being Intel, it could force everyone to switch" to the new design, says Linley Gwennap, a longtime chip analyst who heads The Linley Group in Mountain View, Calif. "Intel didn't think there would be an alternative," he adds.

The first Itanium, available in 2001, was a dud. Its successor, dating to 2002, also had a lackluster reception. Software writers found Itanium difficult to program. Worse: It didn't run most programs dramatically faster than Intel's 32-bit Xeon chips, it radiated tremendous heat and it was expensive. In April 2003 AMD plunged into the gap with Opteron, which runs both old 32-bit software and revved-up 64-bit software. "It may look like magic, but it wasn't," says Martin Seyer, vice president of AMD's microprocessor group. "Customers wanted to protect their software investments."

It was only last June that Oracle, IBM, Microsoft and others finally began selling databases written for Itanium. "Last year was a watershed year for Itanium," declares Lisa Graff, who is director of Intel's Itanium group. That's faint praise: Intel sold 110,000 Itanium chips last year--a big boost over the past but barely a ripple among last year's estimated sales of 2.9 million 32-bit Xeon servers.

HP executives are quick to say that Opteron best fits systems in which one to four processors will do the job. Itanium, they argue, suits those with the biggest computing loads, such as large databases or scientific modeling that require eight or more processors. "We have no illusions about making that market available to AMD anytime in the future," HP's Marcello says. Counters Ruiz: "Our path to pervasive 64-bit computing remains clear, while our competitor's only becomes increasingly muddy."

But the rise of Opteron has injected competition into a part of the market where the only color was Intel blue. Sun has its own 64-bit UltraSparc chips running its own Solaris software, but it is now also heavily flogging a low-priced Windows-compatible line using Opteron chips to appeal to a huge base of customers it was missing. Says Sun's chief architect, Andreas Bechtolsheim, "With the exception of UltraSparc, Opteron has the best performance of any chip we've seen." Cashing in the Chips

Rivals to Intel reap more per server shipped. Itanium is its pricey response.

Forbes: Too Hot to Handle

Forbes.com


William Pohlman's 1999 retirement party, capping a 20-year tenure at Intel, had barely started when two former colleagues pulled him aside. They wanted him to help them start a new chip company, Primarion, which wound up focusing on regulating the energy demands of microprocessors. The back nine could wait. "I knew the technology megatrends that were creating problems for building future chips," says Pohlman, a former vice president of engineering in Intel's microprocessor group.





Two years later Intel (nasdaq: INTC - news - people) is pulling off breathtaking feats, squeezing 42 million transistors onto a sliver of silicon 217 square millimeters. Its new Pentium 4 churns through data at rates of 1.5 gigahertz; one gigahertz is a billion clock cycles a second.

But as chips get this dense and quick, they get hot�hot enough to boil water. The heat makes them so electrically "noisy" that they can fail. And the materials that enabled such chip density are reaching physical limits. Says Pohlman, now chairman of Primarion in Tempe, Ariz.: "We've hit an inflection point."

And it's a biggie. If nothing is done to rethink chip design, the most powerful microprocessors could be consuming more than 1,000 watts by 2004. "If it's business as usual, we wind up frying eggs" with microprocessors, says Dennis Monticelli, a Fellow with National Semiconductor (nyse: NSM - news - people) in Santa Clara, Calif.

Many of these problems could occur within two chip generations, about four years from now. Since it takes about two years and more than $1.5billion to build a new semiconductor factory, chipmakers are rolling some expensive dice betting researchers will find solutions in time. "Our goal is to make Moore's Law work for the next decade," says Patrick Gelsinger, chief technology officer at Intel, referring to the tenet that the number of transistors on a chip doubles every 24 months.

Doing so, however, will demand changes in the design of chips and the materials that compose them. At a recent industry conference, Gelsinger declared that managing heat is now one of the industry's top challenges. Switching every transistor off or on requires a touch of energy. As transistors shrink, it becomes impossible to completely turn them off, so they leak current all the time. That draws electricity�50 watts in the case of the Pentium 4�and the electricity creates heat. Without the use of cooling techniques, temperature spikes above 105 degrees centigrade have occurred. Piping out the heat is expensive. Even simple "heat sinks," chunks of material that carry heat away from microprocessors, can add $16 to the cost of a $600 chip. More elaborate models, with tiny chambers of water that vaporize and carry away heat even more quickly, can run twice the cost. Computer makers hate adding gizmos to their boxes to flush out heat, preferring to save the room for gear that makes their machines more appealing.

New cooling tricks are starting to emerge. In late February the fledgling Incep Technologies in San Diego introduced a technique for packaging together a microprocessor, a logic board for regulating power to the chip and a heat sink. Even though such "encapsulation" could cost $200 per unit, Incep President James Kaskade contends that it both cools the chips and saves space inside the box.

Isonics Corp. (nasdaq: ISON - news - people), in Golden, Colo., a maker of specialty materials and chemicals, is proposing a new material:a "purer" version of silicon called Si-28, which channels out heat better than conventional silicon. The silicon in typical wafers is a blend of three silicon isotopes. Sifted down to just the Si28 isotope, Isonics' wafer conducts heat better.

Even though Si28's thermal properties are attractive, changing materials could be an expensive option, adding at least 25% to the cost of the wafer. Isonics Chief Executive James Alexander says he needs committed partners before manufacturing the first wafers. He claims that Advanced Micro Devices (nyse: AMD - news - people), among others, is experimenting with the materials.

Even better than getting the heat out would be generating less of it in the first place. Intel's Gelsinger is exploiting several tricks to make chips more efficient. Adding more local memory, or "cache," to a chip reduces the work the microprocessor must do to fetch needed data. Letting two microprocessing units share one cache cuts work even further. Designating a special section of the chip to handle common tasks also helps. So, too, does handling repetitive tasks together.

Both Intel and AMD are also trying to be smarter about how their chips use power by using software to deliver just enough juice to the chip to get a job done. "The chance that you need the highest performance at any one time is small," points out Frederick Weber, vice president of design engineering at AMD in Sunnyvale, Calif. Instead, chips might operate at clock speeds ranging from 300 megahertz to 1,500 megahertz, depending on the tasks.

Transmeta (nasdaq: TMTA - news - people), a much-talked-about Santa Clara newcomer, is taking a different approach entirely. Instead of slowing down a fast processor, it is using software to replace transistors. Transmeta's technique, called "code morphing," translates the instructions sent to a chip into bigger chunks that can be handled more efficiently. The result: Its Crusoe chip, which uses about 1 million logic devices such as transistors, is already used in Sony and Hitachi laptops. Transmeta and its competitors argue about whose chip performs at what speed. "Racing for megahertz isn't the goal�giving consumers a great experience is," says the company's founder and chief technology officer David Ditzel.

A more insidious problem, the one that lured Bill Pohlman out of retirement, is the dreaded power spike. Operating at gigahertz speeds takes a lot of energy, so designers must lower the voltage they apply to transistors so as not to fry the electronics. But at lower voltages the signal that pulses through the chip gets so weak it could get lost in the chip's electrical cacophony. Imagine 50 million doors slamming every fraction of a second. And, when the electric potential dips below one volt, devices may not get enough juice to switch. A power-hungry transistor will steal energy from its neighbors, causing a tiny surge on the chip. "Either you have to run your processor slower, or you could get a �blue screen'�the system fails," says Pohlman.

He thinks he has an answer to these concerns by judiciously managing the voltage. Primarion is designing small, special-purpose silicon germanium chips that sit next to a microprocessor, monitor its energy demands and supply the right amount of power at the right time. "We think it might add $20 to the cost of the microprocessor but it could run as much as 20% faster," Pohlman argues. Primarion's first chips, which operate about five times as fast as the top microprocessors, might be ready by year-end. (Silicon germanium chips run so fast because electrons travel more easily through the material than they do through silicon.)

As transistors get even smaller the materials that have been so reliable for chip designers begin to give out. One standard ingredient has been silicon dioxide, a combination of silicon and oxygen atoms that makes up beach sand and quartz crystals. Silicon dioxide has played two different roles for transistors: It insulates the tiny metal wires connecting those millions of transistors and manages the process of turning a transistor's power off and on, serving as a buffer between positive and negative charges. By thinning this "dielectric layer," designers have sped up transistor-switching. But it will soon be stretched about as thin as it can go: The silicon dioxide layer on the daughter of the Pentium 4 will be a mere six atoms thick. Designers can't scrape away too many more atoms or else those lines will touch or interfere, garbling the digital signals.

Researchers despair of ever finding another material that can both manage the switch and insulate the wires. That leads them in different directions: adding new materials to the dielectric material governing the switch and trying to concoct new insulators for the wires. IBM and others are trying a grocery list of materials. In early March, for instance, Dow Chemical (nyse: DOW - news - people) unveiled a porous organic material that it promised to make available as an insulator later this year. One radical idea for insulating the wires would be to leave nothing but air between them, says Daniel Dawson, a manager at IBM's Almaden Research Center. Such a chip might be too fragile, however.

Many solutions are under way, but if the biggest chipmakers don't settle on an approach, it will be difficult to drive down the costs of future chips. One compromise: throwing in a pair of oven mitts with every new computer.

Getting The Heat Out

To make more powerful microprocessors, engineers try to squeeze more transistors onto a single silicon chip. That means transistors have become vanishingly small. If Intel's top–of–the–line Pentium 4 processor measured 500 miles on a side, then each of its 42 million transistors would be only 19 feet across the top. But the tinier the transistors, the hotter the whole chip becomes. Here are a few of the techniques designers are trying to get the heat out. Just about all of these, however, add some cost and difficulty to chipmaking.
FIND A BETTER WAY TO
FLUSH OUT HEAT
USE DIFFERENT MATERIALS REDESIGN THE CHIP
1. Heat sinks. These are chunks of material that pull heat away from the microprocessor. Metal is a good conductor of heat, water is better. (Air is the best.) Some designers are building novel heat sinks with tiny water chambers. The water draws out the heat, vaporizes and, as it cools, condenses again.
2. "Encapsulate" a microprocessor. Startup Incep hopes to package a chip, heat sink and the ability to modulate voltage. By sliding the chip into this tidy package, it could expose more of it to air.
Some firms are exploring how different materials flush out heat or switch faster with less voltage.
1. IBM's "silicon on insulator" layers silicon and an insulator such as silicon dioxide where current passes through the semiconductor.
2. Materials–maker Isonics pushes the idea of using isotopically pure silicon wafers that have fewer crystal defects than conventional wafers. Electrons pass through with fewer road bumps, generating less heat. Isonics is seeking a commitment from a big chipmaker before it begins manufacturing such wafers. Chipmakers are nervous about the cost.
1. Add more local or "cache" memory. To do a task such as addition, a chip might have to fetch the numbers from the hard drive. Adding more cache memory means the chip does less work to find the data.
2. Add specialized processing blocks. Creating a section of the chip designed to handle repetitive tasks efficiently saves work.
3. Add another processor, but share the memory. Creating two processing units that share a large cache on the same swatch of silicon speeds up work.
4. Use software to find parallel tasks. In the most radical case, software might be able to reorganize a problem so that a chip can handle several tasks simultaneously. Software can also let a processor work as if it were two units when it's only one. -E.C.
