Andreas, Yes, exactly. And 5.2GB/sec with PC2600 DDR RAM -- that's over 50% more than i850 can deliver (3.2GB/sec) without the latency disadvantage. Did you notice in the specs of Tyan 760MP motherboard (posted earlier) that it said the memory was DDR with speed (or type) saying "NDA". I wonder if 760 MP will support faster FSB. Joe

Andreas - RE: "Yes, exactly. And 5.2GB/sec with PC2600 DDR RAM -- that's over 50% more than i850 can deliver (3.2GB/sec) without the latency disadvantage. The only problem is that the FSB won't keep up with this speed." So having a 128 bit SDRAM memory bus is like having a four lane highway and having dual Rambus channels is like having two separate two lane highways. But the Rambus highway has two "hubs" to receive the data, does the SDRAM just have the one memory controller? I thought one of the big advantages of DRDRAM is that you can add another memory channel with not a lot of trouble. But if nvidia can just double the memory bus instead that isn't much of an advantage. Unless a 128-bit memory bus is a lot tricker to deal with and more expensive to implement.
