Or the memory bandwidth. The intel 7505 chipset used in the experiment has a very low memory throughput. On a ~2 year old DeLL 2600 with a i7501 (a kind of i7505 chipset without agp), 2x1.8Ghz Xeon can sustain 500MB/s (memcpy), (540MB/s for the same box with 2x3.0Ghz Xeon).
Indeed, very impressive results.
