curprev 21:0021:00, 6 November 2023‎ Guy Harris talk contribs‎ 13,970 bytes +2‎ x86 refers to the 16-bit, 32-bit, and 64-bit versions of the instruction set. IA-32 refers to the 32-bit version, and x86-64 refers to the 64-bit version; both of those give more details than x86 does. (But is the VEX prefix used in compatibility or legacy mode? I don't think any 32-bit processors support it, so if it's not supported in compatibility or legacy mode, it's not supported in IA-32 - it's x86-64-only.) undo
