<A HREF="http://www.gamepc.com/labs/view_content.asp?id=ngrdram&..." target="_new">click</A> I'm not really impressed, the performance improvement is minimal and could just as easily be accounted for by the differences in motherboard, for the RIMM4200. As for the RIMM4800, the CPU was overclocked as well!
It still looks like when DDR reaches the same bandwidth (easily achievable through dual channel DDR), it will pass even RIMM4800 performance, simply by using two PC2400 modules.
Just so you know, right now after 3.2GB, any future RDRAM used on P4 is purely for the latency purposes, like DDR, it ain't about bandwidth.
This is why I find Raystonn's 78.2GB/sec in 4 years theory a bit odd. Although true from his sayings, that is IF Rambus stays alive, who knows if the next architecture by Intel really will go for 78.2GB/sec, just after the 3.2GB of the P4?
No, that would be 4.2GB. You see, 4.2GB/s is the same bandwidth as the QDR533 CPU bus offers. It's not like using PC2700 on AMD's DDR266 bus. 4.2GB/s is the PROPER transfer rate for the "533" bus. It's the same rate as offered by PC1066. With only 3.2GB/s on the "533" bus, your memory become the bottleneck as it only has 3/4 the bandwidth of the CPU bus.
