AMD chipsets seem to have better (integrated) multilevel memory management than comparable Intel ones. This makes a big difference for traffic intensive applications. Recently two colleagues did extensive benchmarks on the way to pick a 128-CPU supercomputer to run multiphysics simulations. Ended up buying an AMD cluster, which was able to sustain 4 TFlops. Handily beat IBM Power in price performance. In terms of pure 64-bit FP performance IBM was better at the same clock rate but more expensive. Intel seems to be way behind the curve in both CPU power and memory management for historical reasons. They put much time and effort on the Itanium flop. Leaving them enough time, they could overtake up AMD with low-power multicore. They have huge manpower resources.
