Re: for DRDRAM-800, latency will be similar to any SDRAM I continue to be amazed by it, but the datasheets seem to be showing a pretty compelling advantage (in terms of latency) for PCXX. Here are some from micron: micron.com Showing 400/800 still at 40, 45, and 50ns for both 356/700 and 400/800 drdram Now here is PC166: micron.com Showing latency as low as 8ns - the micron datasheet shows these parts support cas 1 ! Here is newest generation PC100 / PC133 - this is what is between 1/4 and 2/3 the price of rambus: micron.com it is listed as supporting cas 2 at PC100/PC133 and cas 3 up to 143 This is an improvement over the original cas 3 pc100 - but it's the PC166 - not ddr, unless ddr can support the same latencies, that I think will devestate rambus in real world applications, given the chance. I'm sorry if I wasn't clear, but I was comparing bandwidth for PC100 (= 1 x 100) with DDR 133 ( 2 x 133 = 266) in the other discussion, which should give a 2.6 x bandwidth gain. Dan
