Chip maker Intel plans to demonstrate a processor with 64bit extensions during the upcoming Intel Developer Forum (IDF), confirming speculation that the company would respond to the processors unveiled by rival AMD last year.
Rumours have circulated for years that Intel has developed and tested a product with 64bit extensions called "Yamhill." The company has never formally acknowledged those rumours, but after three of the four major server companies gave notice that their customers are inquiring about servers with chips that bring the x86 instruction set to 64bits, Intel is prepared to talk about such a product, sources said.
AMD's Opteron server processor is almost a year old. It brings 64bit capabilities to 32bit processors with the x86 instruction set that has provided the marching orders for most of the world's computers during the last 20 years. AMD also released the Athlon 64 desktop processor with the same technology in September.
Ever since AMD announced its plans to extend the x86 instruction set several years ago, Intel has denied that a market for servers with that technology would emerge by this point. In interviews one year ago at the 2003 Spring IIDF, executives said that a 64bit market for desktops and low-end servers probably wouldn't be ready until the end of the decade.
But IBM and Sun Microsystems announced plans to deliver servers based on the Opteron processor last year, and HP said this week that it sees a demand for "x86 extensions technology" and is currently evaluating its options.
"Intel has likely had this in its back pocket for some time, and Opteron is clearly gaining marketplace momentum. Intel just didn't feel it could sit back and hope the problem would go away any longer," said Gordon Haff, an analyst with Illuminata in the US, after learning of the demonstration.
Details were not available as to whether Intel would demonstrate a desktop or server processor during the show. An Intel spokesman declined to comment on any plans for demonstrations at the show, which takes place in San Francisco 17 to 19 February.
Intel President and Chief Operating Officer Paul Otellini told an analyst in an interview this week that Intel wouldn't release an x86 64bit chip until operating system and application support was available. Microsoft plans to release a version of Windows that is compatible with AMD's technology in the second half of this year.
It is also not clear if Intel's extensions technology is compatible with AMD's technology, but the reluctance of Microsoft to develop and support separate operating systems for each processor would probably point to compatibility, said Nathan Brookwood, principal analyst with Insight 64 in California, in an interview this week after HP revealed it has encountered demand for this technology.
