AMD is working on a way to make a multi-core processor appear to the host operating system as a single-core chip, it has been claimed. If true, the move turns on its head the drive to develop multi-threaded apps the better to take advantage of multiple cores.

The technology is aimed at the next architecture after K8, according to a purported company mole cited by French-language site x86 Secret. It's well known that two CPUs - whether two separate processors or two cores on the same die - don't generate, clock for clock, double the performance of a single CPU. However, by making the CPU once again appear as a single logical processor, AMD is claimed to believe it may be able to double the single-chip performance with a two-core chip or provide quadruple the performance with a quad-core processor.
