A CPU can be made to have any kind of instructions you want, really. It just depends on if Intel or AMD thinks a given instruction would be used often enough to actually be useful.
The SSE extensions are all SIMD instructions (single instruction multiple data). They perform the same operations, but on more than one chunk of data at a time
Anyway I was referring to micro ops, not x86 instructions
