EM64T & x86_64 only exist because Intel has too much pride to call it what it is: AMD64.

EM64T & x86_64 only exist because Intel has too much pride to call it what it is: AMD64.
- scott_karana 13y agoThe name "x86_64" existed before AMD fully released their CPUs, and was latched onto by some of the open-source communities, so that specific one isn't exactly Intel's. But you're right about EM64T. :)
- ChuckMcM 13y agoI do not believe this is true. Do you have a reference that used that name x86_64 before Intel shipped its first AMD64 compatible CPU?
- maggit 13y agohttp://en.wikipedia.org/wiki/X86-64 http://en.wikipedia.org/wiki/X86-64 says "Prior to launch, "x86-64" and "x86_64" were used to refer to the instruction set. Upon release, AMD named it AMD64." and refers to https://wiki.debian.org/DebianAMD64Faq https://wiki.debian.org/DebianAMD64Faq which says ""AMD64" is the name chosen by AMD for their 64-bit extension to the Intel x86 instruction set. Before release, it was called "x86-64" or "x86_64", and some distributions still use these names." I, myself, had an AMD Opteron machine on which I ran an x86-64 build, with that name for the architecture, of SUSE Linux before Intel released their EM64T.

- ChuckMcM 13y agoAwesome thanks. I stand corrected.
