Well, latency is probably more important than bandwidth. Unfortunately, Rambus tech. doesn't really address this issue...

JDF,

Thanks for the advice. However Memory speed will be the bottle neck of cpu speed and w/o adopting the correct RAM tech.,we will have a last mile problem on the motherboard.

Well, it is a bottleneck to some extend, but it is being addressed by number of different ways.
- large on-chip caches - going to 512K on mainstream processors
- prefetching
- moving memory controller on CPU die to reduce latency
- dual channel chipsets

Joe
