Intel concedes defeat on 64-bit extensions

Intel has confirmed that it will build 64-bit capabilities into its 32-bit chips later this year after all.

The company said that, starting in the second quarter, it will introduce 64-bit memory extension technology to its IA-32 architecture for server and workstation processors.

The move will bring capabilities previously reserved for enterprise computing down to lower end computers, and will enable the firm to reduce the competitive edge currently enjoyed by AMD's comparable Opteron chip.

64-bit technology allows computers to efficiently access extremely large amounts of Ram compared to the 4GB of Ram that can be used by 32-bit systems.

Intel's chief executive, Craig Barrett, told delegates at the Intel Developer Forum in San Francisco: "Offering a broad line-up of solutions means that when combined with the Itanium processor family, which is designed specifically for business-critical, high-end server and technical computing market segments, we can provide leadership solutions from top to bottom in a variety of 64- and 32-bit configurations."

And, describing it as "the worst kept secret in San Francisco", Barrett confirmed that new 64-bit Xeon chipsets would be coming out this year.

But the move by Intel can only be seen as a catch-up measure resulting from pressure imposed by chief rival AMD, which already offers 64-bit capabilities in its most popular chips.

Indeed, Barrett also confirmed that the new 64-bit support is compatible with that used by AMD in its 64-bit Opteron processors, so firms should be able to use the same software on the new 64-bit Xeons as they do with Opteron-based systems.
