I have to add that unfortunately, transition to new production process didn’t let AMD increase the frequency of the on-die North Bridge and it still works at 1.8GHz in the new Phenom II X4 processors. It is really sad, because had this frequency been increased, the L3 cache and memory subsystem performance would have improved much more than after a slight reduction of the L3 cache latency
