Chuck, re:<One thing for sure - VIA seems to be biggest beneficiary - looks like they are getting pretty much all the desktop PC133 design wins right now> This brings up a point about VIA that bugs me. Their chipsets are just not as fast as Intel's. The benchmarks I've seen (Anand, I think) show not much benefit from PC133. Acually, they showed that in four out of six applications, the Intel BX outperformed the Apollo PRO 133 (both chipsets at 100 MHz); running the Apollo PRO at 133 MHz was barely enough to make it as fast as the Intel BX at 100 MHz. In the other two applications this situation was reversed with the VIA chipset beating the Intel. For these two apps, going to 133 MHz added 2 to 7% additional performance. The VIA Apollo PRO 133 is particularly weak on AGP performance. Unfortunately (for AMD) VIA's chipsets seem to penalize a CPU by a few percent, and their AGP performance is particularly poor. (AGP 2X, who knows what 4X will look like!) I doubt that the engineers at VIA are dumb, its just that there are tricks that can be done in the chipset if you know the innards of the CPU. Hopefully, the Athlon chipsets will have this "inside knowledge" advantage. Petz
