Tench: VIA's DDR chipset for Pentium III did not show much of a performance improvement over PC133. The FSB was a limiting factor, even though it is very efficient.

Based on this single counterexample, I expect the extra memory bandwidth on nForce to be useful only for the integrated graphics, not for the CPU.

There are two very significant differences:

NVIDIA's chipset features a prefetch cache of some sort (DASP or some such acronym).

For Palominos, there is also a separate, complementary prefetching unit.

Both of these will enable the system to better utilize "extra" bandwidth.
