It was called AMD64 when AMD and Microsoft designed it, but Intel objected using the term when they adopted the architecture and coined their own: EM64T. So, Microsoft came up with a compromise and started calling it x64.
- cesarb 3y ago> It was called AMD64 when AMD and Microsoft designed it, The original name was x86-64. Quoting myself (https://news.ycombinator.com/item?id=36075840 https://news.ycombinator.com/item?id=36075840): > I still shake my head at how they were able to successfully rebrand it from amd64 to x86-64 It's the opposite: the original name was x86-64, and amd64 is a later rebranding. See, for instance, the original web site for this (then) new architecture: https://web.archive.org/web/20000829042251/http://www.x86-64.org/about https://web.archive.org/web/20000829042251/http://www.x86-64...
- sedatk 3y agoYes, but that doesn't contradict with what I said. AMD had pivoted to "AMD64" soon after and that was before Intel had released their own name: EM64T. Microsoft coined x64 around that time, probably found it more marketable than x86-64, becuase they had used it in commercial branding such as "Windows XP Professional x64 Edition" too. (They couldn't call Windows XP "64-bit edition" because that term was used for their Itanium-based (IA64) products).
- gmokki 3y agoIntel originally named it "IA-32e" to try to make it sound it was just a small extension on the 32bit x86 architecture whereas the Itanium IA-64 architecture was the future.
- sedatk 3y agoNever heard of that one, but yeah, Intel was very hesitant to admit that IA-64, was, indeed, not the future.
