Dan, Re: "Re: x86-64 requires OS support Wrong again. X86-64 is architected to provide no-compromise performance for any of the millions of programs that make up the installed base of "standard" software." Dan, check out the facts. amd.com:7246/us-en/Processors/DevelopWithAMD/0,,30_2252_875_1024,00.html Q: Will users running 32-bit applications benefit from the underlying 64-bit architecture or just from processor speed advances? A: No. 32-bit applications do not utilize 64-bit extensions. Processor speed advances will help both 32-bit and 64-bit applications and operating systems at the same time. You need to have the application recompiled at the least in order to benefit from the extensions. And who will be supporting these compilers? No one, yet. "Intel is forcing any company that goes with its 64 bit solution to re-write or buy new not just the 2% of their software that benefits from 64 bit processing but also the 98% of software applications that don't." There is only a small number of enterprise level apps that are widely used by the majority of enterprise level businesses, and most of these are being redesigned for IA-64. No support has been announced for x86-64. wanna_bmw

Dan3, re: "Further, those companies will now have a 64 bit platform that can be incrementally migrated to, to accommodate those few applications that are benefited by 64 bit address spaces." In order to benefit from a 64-bit address space and the register extensions does require a new 64-bit OS which I don't consider to be a likely "incremental migration." See page number 2 of the white paper from AMD which can be found here: x86-64.org Any word of non-Linux x86-64 OS development progress? Not that I run any applications that need 64 bit but I am sure that there are application which could with a new compiler take advantage of the extra width and number of general purpose registers when running in Long Mode. -PT
