Re: Athlon and floating point (was: SMP Celeron or UP P2?)

Correct, one difference between the pgi 3.0 and 3.1 releases is that
version 3.1 supports sse on PIII hardware. But as you see on the results
for the stream_d bechmark compiled with the PGI 3.0 Fortran compiler
this makes not much difference in the results:

-------------------------------------------------------------
Function      Rate (MB/s)   RMS time     Min time     Max time
Copy:         312.2868       0.0636       0.0512       0.0924
Scale:        313.4120       0.0621       0.0511       0.1009
Add:          372.2549       0.0752       0.0645       0.1145
Triad:        369.7024       0.0715       0.0649       0.0850

So, I think the direct comparison isn't so unfair.
