Go up one level in this thread

I don't understand where you get your specdata from.
According to spec.org it looks like this:

SPECint 2000 uni processor:

Xeon 3.06 GHz.          1294
Opteron 1800 Mhz.       1170
Athlon XP 2200+         1080

SPECint rate2000 dual processor:

Xeon 3066 MHz. 1Mb.     27.1
Opteron 1800 MHz.       26.8
Athlon MP 2600+         15.7

The runtime for Crafty on 2 CPU's is:

Xeon 3.06 1Mb.          85
Opteron 1800 MHz.       81.2
Athlon MP 2600+         84.5

So according to spec.org there is hardly any difference for Crafty between the
Xeon, Opteron and Athlon-MP.
The dual MP platform scores very badly in the total spec suite, but this is
mainly due to it's bad memory architecture. Chessprograms don't seem to suffer
much from it.
