<I believe that K7's will support ddr-dram next and not drdram.>

Nah, I think DRDRAM chipsets are indeed in the future for the Athlon platform. I don't think AMD really wants to admit it yet because they want to continue to push the Anything-But-Intel image.

My feeling is that DRDRAM is better able to handle the traffic coming from multiple sources such as AGP-4x, PCI, and the bandwidth-hungry Athlon itself. DDR SDRAM is just too inefficient to handle heavy traffic, since it can't support as many concurrent accesses as DRDRAM can. It may have a higher peak bandwidth, but according to Dell's whitepaper, its actual efficiency is around 60%, while DRDRAM's efficiency can approach 95%.
