Aaron, If I'm reading yours and Steffan's test results correctly, Athlon XP 2520 is 1.578 million nodes per second, and P4 3.03 with HT enabled is 1.161 million nodes per second. Your test on Crafty 18.15 and Steffan’s test on Crafty 18.11. Although the different versions of Crafty could account for some difference in speed (which way, I have no idea), the XP 2520 is some 36% faster than the 3.03 with HT. Bob’s test indicated with two CPUs that with HT enabled the HT versions were some 33% faster than without HT enabled. He was comparing P4s at ~ 2850 GHz or so. I see your other results that show that the XP 2520 is substantially faster than the P4 at 3.25 GHz. This means that the XP 2520 is still the speed demon by a wide margin compared to the P4, with or without HT enabled. Is this correct? Thanks!
