A recent article on anandtech.com compared the VIA KT133A and AMD760 chipsets and concluded that DDR on a AMD760 chipset did not have significant performance advantages over the KT133A when using 266FSB CPUs. Here is what I have been trying to post to the anandtech articles forum but it seems to be stopping me?!?
I think the main reason that the VIA chipset looked so good when compared to the AMD760 with PC2100 is that the VIA used PC133 rates at CAS2 where as the PC2100 was rated at CAS2.5. If the tests were re-run with the PC2100 ram running at CAS2 (should be stable) then I feel that the significant performance advantage of the DDR setup would be shown. Although PC2100 ram is more expensive than PC133, PC1600 already sells for the same as PC133 and once more DDR ready motherboards are available, prices should fall. I also expect that once motherboards equipped with the AMD760 chipset become widely available, the price of these will also fall inline with VIAs offerings.
Toms article with CAS2 ram showed just over a 10% advantage with DDR under Quake3 where as Anand's review showed just over a 4% advantage with the DDR setup. Anyone else got any thoughts. Am I missing something?
