Sorry Vincent, you are as always only partially right :-) Let's look at the SpecInt2k number. It's geometric mean of the 12 *real-world* integer programs, one of them is old Crafty version. Best SpecInt2k for AMD I was able to found on www.spec.org is 720 base / 749 peak for Athlon XP 2100+. Best official Pentium 4 result is 819 base / 833 peak for 2.4GHz processor. Unofficial (not yet submitted to SPEC) result for Pentium 4 2.53GHz is 882 base. So, for mix of real-world programs, Pentium 4 is definitely better. You can compare results yourself: http://www.spec.org/osg/cpu2000/results/res2002q2/cpu2000-20020422-01326.asc http://www.spec.org/osg/cpu2000/results/res2002q2/cpu2000-20020401-01279.asc Of course YMMV. You can be unhappy person who need to run the application that is slow on Pentium 4. So let's look at the individual result: Crafty on P4/2.4 runs 123 seconds. Crafty on AMD/2100+ runs 98 seconds. I.e. ~25% slower. Definitely less than 70% you are writing everywhere. My prediction is that with the widening clock speed difference (caused by design decisions Intel made during P4 development) we'll soon see P4 that runs Crafty faster than any shipping AMD processor.
