Unfortunatly Ray I read that last think and honestly think you lost that battle. Do all the math you want, don't mean squat. there are lots of devices that have great specs on paper, but in real life they never live up to there theoritical performance. to date we only have one processor to compare Sdram and Rdram, and Sdram was proven to have less latency. Until a chipset comes out to compare DDR against Rdram on the same platform we can argue this point till we are all blue in the face, and no one will win. True, RDRAM has greater bandwith, but the discusion is latency, not bandwith. If it had both then it would have performed as least as well on the p3. I can take a cas2 pc 133 sdram module and stick it in a pc-66 motherboard and its latency will not decrease. Sure its bandwith will drop do to the decrease in bus frequency but not its latency.
A little bit of knowledge is a dangerous thing!
