[citation][nom]stradric[/nom]It's RISC or Reduced Instruction Set. Which basically means it sucks for multimedia applications and all that fun stuff that people do on their home PCs. The processing pipeline is much smaller and far less complicated than that of our x86/x64 processors. So, in other words, it would be quite a more difficult task to take on Intel and AMD with regard to consumer CPUs. An undertaking that would almost certainly cost Fujitsu more money than its worth.[/citation]
Good points. No "MMX, SSE, SSE2, SSE3, SSE4, EM64T". They would also need to get licenses from Intel and AMD for the x86 and other techs.
