Tweakers Australia has updated their PC1066 RDRAM vs. DDR SDRAM article
Currently RDRAM memory modules run on a data bus of 100MHz (PC800) and 133MHz (PC1066). Up to 1.6GB/s of memory bandwidth per channel can be delivered by PC800 RDRAM on a 100MHz data bus, while the new breed of P4s run on a 133MHz (133MHz*4=533MHz) data bus, delivering up to 2.1GB/s per channel with PC1066 RDRAM. The P4 can make use of the full 2.1GB/s because it runs on the same data bus PC1066 is designed for, using a far superior memory technology in contrast to DDR SDRAM. Just recently 133MHz PC1066 was launched, although unofficially supported by the new Intel P4 and the Intel 850E core logic chipset, but still promises to bring memory performance to the next level. Lets find out…Read more
