If you go from 2.2 GHz to 2.4 GHz, you speed goes up pretty much by (2.4-2.2)/2.2. (Assuming same architecture of course.) In fact the speedup is a tiny bit less than that, because the max memory speed is the same on all of the Opterons. BTW in the CCC archives you will find some crafty benchmarks on the various Amd64 systems. Vas
