> The name “x86-64” wouldn’t be invented until 2006. While x86-32 is AFAIK a backronym which would only be invented later, the original name of the AMD64 architecture is x86-64, and has been since that architecture was first revealed at the turn of the millennium. If you weren't following these developments back then, you can still see it for yourself in the Internet Archive: https://web.archive.org/web/20000817014037/http://www.x86-64.org/ https://web.archive.org/web/20000817014037/http://www.x86-64... is the earliest snapshot of the official page for the x86-64 Linux porting effort, which links to https://web.archive.org/web/20000817071303/http://www.amd.com/news/corppr/20152.html https://web.archive.org/web/20000817071303/http://www.amd.co... which is a snapshot of a press release dated 2000-08-15 announcing that porting effort. Quoting from that press release: "AMD publicly released its 64-bit architecture specification, the x86-64™ Architecture Programmers Overview, last week to enable the industry to begin incorporating x86-64 technology support into their operating systems, applications, drivers, and development tools." That is, the x86-64 name was first used publicly, as the official name of that architecture, no later than early August of the year 2000.
