The chip, once code-named McKinley, will be touted in benchmark studies, product releases and analyst reports all this week as part of its debut. Executives at Santa Clara, Calif.-based Intel say a major redesign of the chip and improvements to the accompanying software and hardware will provide far better performance than the original Itanium, which was a major disappointment for the company.
"It takes a second try to hit the performance goals you want," said Lisa Hambrick, director of enterprise processor marketing at Intel.
And servers containing the chip will cost less and outperform similar RISC/Unix servers from Sun Microsystems or IBM, allowing Intel to participate in a lucrative market where chips can sell for $4,000 each and servers for more than $1 million.
Analysts generally agree the new chip will shine on benchmarks and be popular in areas such as biosciences that require heavyweight numbers crunching.
Tim Shetler, vice president of TimesTen, which makes real-time databases for telecommunications companies and large financial firms, said his customers haven't shown enough curiosity about the chip to justify a major shift in how his company designs its products.
"There is not a lot of demand right now beyond a handful of interested inquiries," he said. "Certainly not enough to disturb the normal pattern of serving 150 paying customers."
The company has received venture capital from Intel's IA-64, which invests in businesses to encourage them to develop Itanium applications. And TimesTen will come out with a Linux/Itanium version of its application later this year. But for the most part the company will concentrate on its products for the familiar, and comparatively inexpensive, servers based on Intel's 32-bit Xeon chips, where it's seeing most of its demand.
Roland Baker, president of NetExpress, which sells servers and workstations to universities and chip designers, sees a similar situation: Customers want Linux boxes with Xeon or AMD Athlon chips and show little interest in Itaniums of any stripe.
The lack of urgency from corporate customers is reflected in the varying product plans of Intel's major partners. HP, IBM, Fujitsu and others will release new Itanium 2 machines during the next few weeks. On the other hand, Dell is stillwhether to release Itanium 2 machines, while Microsoft has yet to release a final version of its Windows server operating system for the Itanium family.
Microsoft on Monday said that Windows Advanced Server Limited Edition 1.2 would ship to PC manufacturers later this month. The new version incorporates 64-bit code development from Windows .Net Server, which is tentatively scheduled for release late next year. The company also plans to offer Itanium 2 support for Windows .Net Enterprise Server and Windows .Net Datacenter Server.
Microsoft also said Monday that it will ship the 64-bit version of Windows XP in the first quarter of 2003. The company anticipates the new version of XP will appeal to businesses doing complex scientific research, software development or 3-D animations on Itanium 2 workstations.
"These guys (corporate IT managers) are glaciers when it comes to moving their equipment around," said Kevin Krewell, an analyst at Microprocessor Report, a semiconductor industry newsletter. "People aren't going to buy a bunch of these servers until the software is there. Who is going to commit their business to early release software?"
Instead, volume sales won't begin until next year with the release of McKinley's successor, a chip code-named Madison, Krewell said. That time frame should sound vaguely familiar, Krewell said. When the first Itanium chip came out, Intel and others said it was a test chip. Volume shipments, according to conventional wisdom, would begin with Itanium 2.
The Itanium saga
The Itanium saga has gone on for more than a decade. In December 1988, Hewlett-Packard on a new chip architecture called EPIC, said Dick Lampman, leader of the effort and now director of HP's Labs. The project was cloaked in secrecy, with a "black budget" that made funding difficult to trace.

Some Intel design teams advocated getting to 64-bit chips by merely stretching the existing 32-bit architecture, sources said, a relatively easy leap in terms of engineering. And as an added bonus, both chip families would be able to handle the same software. Intel performed this sort of stretching magic when going from 16-bit to 32-bit chips in the early 1980s (and likewise when it moved from 4-bit to 8-bit to 16-bit chips in the 1970s.)
But for the 64-bit chips, the company decided to work with HP on building processors around the EPIC idea. A new software base would have to be created for EPIC chips, but the switch would also let Intel break free of many of the inherited twists in the "IA" architecture, the design behind all the other the Intel processors.
By the mid-1990s, the future EPIC chips, known by the code name Merced, loomed as a danger to Sun Microsystems, Digital Equipment, IBM and other server makers that also made their own chips. With its mass manufacturing capabilities, Intel would be able to pump out low-cost, high-speed 64-bit chips faster than these individual manufacturers, analysts said at the time.
Making Merced, however,difficult in practice and, after several lengthy delays, the chip went from being a giant killer to a conceptually interesting test vehicle. The chip finally came out commercially in May 2001. Performance was relatively anemic, and sales were even worse. In the third quarter of 2001, less than Itanium servers were shipped, according to IDC.
So what's new?
But although the first Itanium was a flop, newer versions could succeed. For one thing, Intel still wields a larger manufacturing base than any other chipmaker, giving the company an inherent advantage when it comes to lowering costs, accelerating speeds or developing multiple products simultaneously.
"In the long run--even in the short run--our capabilities in manufacturing will keep us ahead," said enterprise-chip marketing chief Hambrick.
A four-processor Itanium 2 server with 8GB of memory will cost around $41,000, less than competing Sun servers. In contrast, a Sun Fire 3800 with four 900MHz UltraSparc III chips with 4GB of memory goes for $133,000, according to Sun's Web site. Hambrick says that on benchmarks the Itanium 2 system will outperform this machine.
Lower prices, combined with improved performance, will certainly make Itanium 2 more attractive than its predecessor, said TimesTen's Shetler.
"It looks more promising," Shetler said. "With the recession, it becomes even more of a viable option."
Sun disagrees, saying Itanium will be the more expensive option.
"The migration costs are going to be very big, there is very little software available and it's an unproven architecture," said Martin Chorich, a Sun spokesman. "This is the second time out with a demonstration vehicle."
Another factor is that Intel has put tremendous amounts of energy and money into building a world around Itanium. The IA-64 fund invested approximately $250 million in start-ups to get them to develop Itanium applications and worked extensively with established hardware and software manufacturers to get them to make Itanium-based projects. Consulting and testing labs were set up around the world so large corporate buyers could tune their applications for the new chip.
Intel will evencomplete servers for manufacturers who can't spare the engineers. This option is expected to be popular with manufacturers in developing nations, such as Russia's Kraftway, said Phil Brace, a marketing manager for Intel.
The company has also straightened out many of the kinks that held back the original Itanium. The photos of the core of the original Itanium looked like a "collage" of chip components rather than a tightly integrated processor, Krewell said.
"They slapped the first one together to get it out the door after it slipped so badly," Krewell said.
Itanium 2 is vastly improved. It contains a 400MHz bus that's 128 bits wide, compared with the 64-bit wide bus on the original Itanium, a change that allows for greater data transfer rates. The level three cache, a reservoir of memory for rapid data access, goes up to 3MB.
The "pipeline," which serves as a kind of assembly line inside the processor, is also shorter. In addition, improvements have been made to the compiler, software that organizes and schedules how different resources on the chip will get deployed, Krewell said.
"In the technical computing space, they need the extra performance," said D.H. Brown's Ghatpande, predicting that scientific institutions and life sciences companies will adopt the chip relatively early.
Security will also improve. Like other chips, Itanium 2 can wrap data within varying levels of security. Itanium 2, though, can hold more data at the highest security levels because of data management techniques developed at the University of Washington, HP and Intel, according to John Crawford, Itanium's chief architect.
Despite the improvements though, the fact remains that performance and security considerations are secondary for many corporations, said Dan Kuznetsky, an analyst at IDC. And even cost isn't necessarily the deciding factor. Companies also take a serious look at the headaches involved in incorporating new breeds of hardware and software into their organizations. Even if Itanium 2 servers cost less, businesses aren't inclined to begin the arduous process of installing them for real-world use.
"Experimentation with new hardware, I suspect, is a luxury that few companies can afford," Kuznetsky said. "If they do anything at all, they will buy a small number of systems to test."
And besides, existing hardware is sufficient to solve most people's problems.
"The current RISC systems...provide the power we need," said Nate Robertson, of Clark County, Washington's government technology purchasing office, which opts for HP Unix servers.
