The way around this is a NUMA architecture, but that's a whole other ball of wax.
Quick note for those reading Ulrich's paper: he refers in a couple of places to Intel's upcoming CSI approach to NUMA. This has now been renamed QuickPath, and it looks like it will be late 2008 before that even makes it to Itanium processors.
The fact that AMD has a good NUMA implementation in their Opteron lines while Intel's Xeon processors do not is one area AMD still has a clear competative lead on. But you need memory bandwidth starved application before that matters more than the fact that the current Xeons are faster in general.
