Tenchusatsu, <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%.> The way I see it, the real advantage of RDRAM is pincount and one has to trade it off against its price disadvantage to see which solution makes sense. I have not yet seen anyone comeup with a realistic application driven performance advantage scenarios that justifies its inclusion over DDR-DRAM. Yes, PC800 can do better than PC266 and yes it will have its niche and yes AMD will support it. But, can you put some some numbers behind your arguments and show a scenario where PC266 would not cut it - as far as application load is concerned? Chuck P.S.: Technically, I think, Scumbria has nailed it w.r.t. ESDRAM. Now, let's see if VIA and memory vendors can market its performance advantage.
