Our newest affiliate, Tweakers Australia has just posted an article entitled 'PC1066 RDRAM vs. DDR SDRAM'. They compare the two using Intel 850E and Intel 845D based motherboards, and even throw in a stick of PC800 to add to the mix. A fairly light read, with lots of juicy benchmarks. Here's a snip:

Most people would know that the memory bandwidth on modern video cards is crucial to performance levels in Direct3D and OpenGL, and overclocking the memory will guarantee an overall boost 100% of the time. Essentially, main system memory goes by the same rule, and is often overlooked in most cases. SDRAM and DDR SDRAM are the most common types of memory used in personal computers across the globe, and offers fairly good performance as well as being very cost effective. RDRAM is another option, originally brought to power with the original Pentium 4, but dumped for DDR to satisfy the low to midrange market. RDRAM is considerably more expensive that DDR SDRAM, and up until now the 100MHz PC800 specification didn't do well in comparison. Just recently 133MHz PC1066 was launched, and is now officially supported by the new Intel P4 and the Intel 850E core logic chipset, but this time promises to bring memory performance to the next level. Lets find out…
