Using two high-end systems. It is my belief that many people are not factoring hyperthreading into the equation (they are acting as if it doesn't exist or makes no difference.) I have observed over 1200 kNs with a P4 3.06 GHz running Fritz 8 on a single thread. Fritz 8 has more knowledge than it's predecessors and, therefore, runs a bit slower as a result. On the Xeon platform, with Deep Fritz 7, (and 4 threads) I can see no reason whatsoever why the 3.06 Xeons should not effortlessly break the 2500 kNs barrier. So far, observing AMD systems the highest kNs I have observed was in the 2400 range. most are in the 2200 area though. I have observed and played against every Dual system on the chessbase server at one time or another. Of course I have no way of knowing what hash size they were running and that factors heavilly into the speed equation. Personally I get my highest kNs in blitz using a 64MB hash even though the t-notes say this is too large. I am not willing to sacrifice even 100 kNs to drop down to the 32 MB hash though.
