Re: "MMX is SIMD you know (Single Instruction Multiple Data)... and you can CERTAINLY use MMX for almost all integer operations.. anything that has multiple additions, subtractions, etc. in integer can be easily (and cheaply converted to MMX)."

Ok, then you raise a question I don't have an answer for, except to say that I don't think Intel needs to use those instructions to see the kind of increase we are seeing for the integer operations. The larger cache, increased bandwidth, lower latency and other optimizations must have accounted for most if not all the integer increase. I'd like to see more detail on the FPU improvements because the previous comments I heard from an Intel insider indicated the FPU SPECs would still trail by a small percentage. Nonetheless, the instructions are there so why not use them? There is nothing to stop AMD from doing the same.
