Aces' Hardware comparison of FPU performance (Athlon vs P4)

[James Cownie]

Probably worth a look, if you're in the market for new nodes for FPU
intensive work (the Intel compiler is available in beta on Linux,
after all) :-

Fundamental conclusion is that the P4 flies when the compiler manages
to use SSE2 vectorisation (and your code isn't bandwidth limited ;-)
For "real" codes like SPECFP SSE2 doesn't win much.
