How old is the Intel compiler again? Both the Pentium 2 and K6 had the MMX extension. Code compiled with the rather popular Intel compiler checked the CPU vendor ID to force programs into badly optimized code paths with disabled extensions on competitors products. It was a nice undocumented feature until 2005 and makes any experienced performance difference suspect.
