JC,

<Note that Quake takes advantage of SSE, not SSE2. Also, specfp's optimizations are mostly or all SSE (prefetch stuff).>

Are you sure? I find it unlikely that P4 FP can outperform P3 unless SSE2 optimizations are in place.

Where do you get this info? My understanding is that all P4 FPU related stuff were being heavily tweaked with SSE2 optimizations for launch.

Chuck
