<Chuck: My understanding is that all P4 FPU related stuff were being heavily tweaked with SSE2 optimizations for launch.> SSE2 has instructions for double precision FP, as well as some integer SIMD. It does NOT include single precision FP instructions. Many of the common FP benchmarks (e.g. Q3 and SPECfp) are heavily bandwidth limited. The SSE implementation of the P4 may also be better than that of the P3, I don't know (JC might, though). -fyo
