Dale: What could become a negative is that during the transition AMD would have to produce multiple variants of the same processor. That is to say, when DDR-II is introduced, AMD will have to continue to offer Clawhammer with a DDR interface even as they introduce a new Clawhammer with a DDR-II interface. And, if they want to produce a DRDRAM variant, this would make three variants being marketed concurrently. That is essentially my worry. By going with an integrated memory controller, AMD would tie themselves to a single memory standard - unless they chose to have multiple versions of the same processor. The thing is, these transition periods are very long - certainly 1 year is not unrealistic (just look at SDR to DDR SDRAM). Looking at the near future, we will have "PC1600", "PC2100", "PC2600" and possibly "PC3200". While these are all DDRSDRAM, the latter two have significantly different physical specifications (if nothing else). They might very well not work with current memory controllers (and, thus, with AMD's theoretical integrated one). When DDR2 comes around (likely within a year of Hammer introduction), that will certainly require a new controller. However, the performance advantage would be very significant. I hope AMD can do it... -fyo
