I'm not sure if this is a test to compare hardware or a test to see which hardware is best for Fritz, but Fritz 8 does not support 64 bit, AFAIK. I don't think the PIV would stand a chance against a native 64 bit Fritz version for the Athlon64. So in this respect, Fritz is not the best benchmark tool. I'd use Crafty and possibly some other opensource chess progrogram that isn't a bitboarder, then test the best 32 bit versus the best 64 bit compiles. I prefer benchmark tools which are opensource, everyone should know that there's no fishy business going on. -S.
