Larger cache to keep Pentium 4 competitive until arrival of dual-cores

Chicago (IL) - Intel's decision to cancel the 4 GHz Pentium 4 580J shifts the bragging rights for the fastest desktop processors into AMD's hands for some time. The Athlon 64 FX-55 and 4000+ outpace Intel's processors on paper as well as in benchmarks. Intel plans to stay competitive with larger cache sizes until dual-core chips are available.

It was no easy move for Intel to scrap plans for a 4 GHz Pentium. At least it was serious enough that Chief Executive Officer Craig Barret brought the topic up at a conference of market research firm Gartner yesterday and apologize in front of a crowd of 4000. The firm's announcement is the most significant public step so far to highlight multicores as the next generation volume processor architecture.

To counter AMD's challenge, Intel will introduce new Extreme Edition processors, starting with a 3.46 GHz variant on November 1 and a 3.73 GHz version in the first quarter of next year. During the first quarter of the next year Intel will also launch a new 6xx-series Pentium 4 family based on the Prescott core.

Compared to the current 5xx-series, the processors will integrate 2 MByte L2 cache, instead of the current 1 MByte. Austin agreed that increasing the cache "certainly" can be considered as an "extension of the life time" of the processor. "The larger cache will be a very competitive solution," he said. According to sources, models offered will include the 630, 640, 650, 660 and 670 with the latter being scheduled for the second quarter of 2005. Clock speeds will range from 3.0 to 3.8 GHz.

While AMD may have a good shot a being able to brag about offering the fastest processor, analysts believe that Intel's business will not suffer dramatically. "This really is a non-issue," said Dean McCarron, principal analyst of Mercury Research. "The very top of the segment represents little volume." He considered Intel's decision as an appropriate step, since the company "apparently could hit a certain level of performance easier with an increase of cache."

Intel spokeswoman Agnes Kwan explained that announcement to cancel a 4 GHz processor does not mean that the company will not hit 4 GHz at some time. Multicore as well as single-core processors are likely to be offered with 4 GHz at some point, she said. This also is an indication that Intel does not intend to abandon its single-core processors completely. "The architecture is not dying," MCCarron said. "There always will be applications, such as office software, cannot exploit the capabilities dual-cores."
