Anyway I was referring to micro ops, not x86 instructions
you got that right.... x86 is architecture.... it doesnt change what micro instructions are flowing through.... every x86 instruction will finally be broken into these microops... the first one of these in PCs was MMX i think.... hyperthreading itself is a SIMD instance at a low level....
