Gainward GeForce 4 PowerPack! Pro/450 Review
"The Gainward card is unusual in the fact that it does not stick to the NVIDIA guidelines; Gainward always try and push each card to give it "something else" over other manufacturers" cards. In this case Gainward have added 5.0ns DDR-SDRAM to the MX420 instead of the SDR-SDRAM depicted above. The additional memory bandwidth provided by the DDR should boost the Pro/450 over other GeForce 4 MX420s."
SiS648 Performance Review
VR-Zone has taken a close look at the new SiS648 chipset that officially support AGP8X, DDR333, MuTIOL 1G and USB 2.0. Interestingly, SiS648 can also support DDR400 too that can further boost the performance and is paired up with the new SiS963 Southbridge. SiS648 was pit against the formidable Intel 850E w/ PC1066 RDRAM and other DDR333 chipsets like Intel 845G, VIA P4X333 and SiS645DX.
