bizpile writes "It was reported earlier that Intel would be delaying the release of their 4Ghz Pentium 4 chips, but it now appears that they will be cancelling them altogether. The announcement came Thursday and Intel says they are going to rely on approaches besides faster clock speed to improve the performance of chips. Engineers are working to add additional cores to a single chip and improving the efficiency in how the chips interact with the rest of the system. Intel spokesman Chuck Mulloy said, "Those are the sort of things where you get more capability out of a processor by designing specific silicon solutions as opposed to just keep turning the clock faster." In the meantime, Intel is planning on releasing a 3.8 Ghz chip with 2mb of cache."
