Het blijkt dat de kt266a boven een dsb van 166 het beter doet dan de kt333CE.
With everything at stock speeds, the KT333CE performs about 1-5% faster then the KT266A chipset which is what we expect. The tide turns once the FSB is upp'ed to 166 MHz! With the 1/2.5 AGP and 1/5 PCI dividers kicking in at 166 MHz FSB the VIA KT333CE based boards and all the peripherals in the computer (HDD, Videocard, soundcard, etc) are all running at default speeds while the VIA KT266A chipset based motherboards are overclocking them all. 3D Performance suffers quite badly from this, office based benchmarks don't seem to have a big problem though.
This brings up several questions; is the AGP/PCI divider a good thing? Should dividers be automatic, or should the user be able to adjust them? Is the 22 MHz difference in the AGP speed at 166 MHz equal 700 3DMarks? How is the memory controller on the VIA KT333CE tweaked differently from the KT266A at high speeds?
We're honestly not really sure what to make of this; while it's great that peripherals run at stock speeds at 166 MHz FSB, we don't like the performance penalty that is associated with it.
Hitting those high bus speeds is nice but if it is going to cost 200-300 MB/s worth of bandwidth for both the ALU and FPU is it really worth it in the long run? In the short term perhaps it is up to the motherboard manufacturers to allow the user to adjust the dividers, so they can get the most performance out of their systems rather then letting it automatic kick in.... perhaps.
