Lower latency is a big deal for AMD while bandwidth is not as important (look at the the 939 3500 dual channel vs 754 3400 singel channel; about the same performance with the 3400 winning a lot of benchmarks because of the 200Megahertz frequency increase).
Intel, on the other hand , due to incredibly long pipelines on their cpu need much more bandwidth to keep it happy. Remember, AMD 64's have a shorter pipeline and need quicker access while Intel has longer pipelines and need more bandwidth to keep them filled.
Thanks
I think you misunderstood what I wrote. What I am saying is that the latency of the DIMMS is not of particular importance to an A64 system. Yes, the on chip memory controller lowers overall latency. And you are correct about the P4 needing more bandwidth. If you still think I'm wrong read this article.

You'll see that RAM timings make little difference for the A64.
