If you do many similar floating point operations, you can use SSE to optimize your code. Crafty doesn't do any floating point operations, so using SSE is impossible. It's possible that Crafty uses MMX for some stuff. I kind of doubt it, but MMX might be used to speed up some 64-bit operations. AMD's chips have always done MMX operations much faster than Intel's chips, so that would tend to make the K6/Athlon faster than the PIII. -Tom
