microbee writes "The register is reporting that AMD is researching a new CPU technology called 'reverse multithreading', which essentially does the opposite of hyperthreading in that it presents multiple cores to the OS as a single-core processor." From the article: "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."

  1. Stumbled upon your blog a week ago and decided to come back. Not for the articles you write, but for how you write them, really amazing stuff you’re doing here, i like how you put information into the articles which makes it much more easier to read and much more interesting of course. Keep up the good work!
