Paul and others, a few comments on AMD's x86-64: I just downloaded the x86-64 specs that AMD released today and glanced over it. I noticed a couple of things: - x86-64 will add more registers. Oddly enough, Sledgehammer will have 16 XMM registers (eight more than Pentium III), but XMM registers are only used by SSE. Does that mean AMD is going to support SSE? What will Intel say about that? - To support the x86-64 extensions, including the additional registers, a 64-bit OS is required. Sledgehammer has a legacy mode for regular shrink-wrapped 32-bit OS's, but none of the x86-64 extensions will be supported. Of course, once you have a 64-bit OS, you can run 32-bit apps at "full performance" as well as gain the advantages of the 64-bit extensions. But this requirement will disappoint those who think they can run x86-64 applications as easily as running SSE (or SSE2) applications. In short, I still don't think Sledgehammer represents much of a threat to IA-64. Maybe it could threaten Pentium 4, but I doubt it for several reasons, including some I'd rather not share at the moment. Tenchusatsu
