I notice that the highest scoring Athlon system submitted to SPEC by AMD itself uses the Intel compiler. Apparently, AMD gets the best results using it too.
specbench.org

I don't understand Dan's commentary about "Real world code creation uses compilers that don't fail to compile on many applications, and are only reliable on the one targeted application".

SPEC2000 runs 25 applications all together and most of them seem to by written by academics which wouldn't have a vested interest in tuning the code for any particular microprocessor.

Of course Intel tunes their compiler to make code run as fast as possible on whatever the latest generation of CPU is. Isn't that what you want in a compiler? If they put in a flag for, "If Athlon detected, produce slow object code", I could see a reason for argument. But they haven't made that flag a feature of the compiler yet. :-)
