Surely 2.2 GHz is not as high as they will go. Take a look at specint.org (There is a test with Crafty) Here quick some numbers: AMD Opteron 148 2,0Ghz : 1506 AMD Opteron 246 2,0Ghz : 1371 AMD Athlon (TM) 64 3200+ 2,0Ghz : 73.0 1370 AMD Opteron 146 2,0Ghz : 1369 AMD Opteron 144 1,8Ghz : 1224 AMD Opteron 142 1,8Ghz : 1094 AMD Opteron 140 1,8Ghz : 957
