While I default to AMD64, Intel 64 is the latest variant from the eponymous manufacturer.
There is some justification for Intel 64, as AMD suffered a series of mistakes and bad decisions, starting with the "Barcelona" Opterons, only recently emerging from these problems.
Intel has been the best-performing AMD64 implementation for much of this standard's time on the market, so a little revisionism must be excused.
- hulitu 4y agoIntel 64 ? You mean the Itanic ?
- chrisseaton 4y agoNo that's IA-64 - that's something else entirely. Intel 64 != IA-64.
- chasil 4y ago"Various names are used for the instruction set. Prior to the launch, x86-64 and x86_64 were used, while upon the release AMD named it AMD64. Intel initially used the names IA-32e and EM64T before finally settling on 'Intel 64' for its implementation. Some in the industry, including Apple, use x86-64 and x86_64, while others, notably Sun Microsystems (now Oracle Corporation) and Microsoft, use x64. The BSD family of OSs and several Linux distributions use AMD64, as does Microsoft Windows internally." "The x86-64 architecture is distinct from the Intel Itanium architecture (formerly IA-64). The architectures are not compatible on the native instruction set level, and operating systems and applications compiled for one cannot be run on the other." https://en.wikipedia.org/wiki/X86-64#cite_note-11 https://en.wikipedia.org/wiki/X86-64#cite_note-11
