Dave,

Were you intentionally being misleading as to the comparison of a P4 RDRAM system with a DDR-II system?

This line of questioning is rather annoying. Each channel of a DRDRAM system gives 1.6GB. Each connection to DDR gives 2.1GB.

I designed a DRDRAM based graphics system which used 12 channels giving a total bandwidth of 20GB. Designs which use more than one DDR connection multiply by 2.1GB per DDR bus.

The point is that it is a very simple problem to calculate the total bandwidth of any memory system. You don't need to buy a P4 system to determine this. Systems which use multiple DDR busses will likewise have very high bandwidth.

We know that P4 has an expensive high bandwidth memory system. The question about P4 is how it does on other tasks besides transferring data from memory.
