Prescott, the code name for an optimized version of the Pentium 4, will continue to be sold under the Pentium 4 name, according to sources close to the company. Prescott chips will contain 13 new instructions to improve multimedia performance and run at higher speeds than existing Pentium 4s. Keeping the name also helps Intel avoid a marketing muddle with the Pentium 4 Extreme Edition. This chip, which was added to the company's product road map this summer, comes with 2MB of cache. Current Pentium 4s have a 512KB cache and Prescott will have a 1MB cache. (ZDNet)
