Anand Shimpi has hinted that ATI's core is quite impressive/interesting, even though his hands are tied by the NDA, it seemed as if he really wants to discuss what ATI/AMD have done.
Well that probably because RV770 is a bigger change in microachitecture from RV670 than GT200 was from G92. Quite a lot has changed actually, no ringbus but more of a hub, TMUs are different, Shader units have also gotten some refinement, RBEs are larger and there is extra functionality build in to make sure that the R700 can be made. That list one is quite a departure from the R680, here they are claiming (dutch source, you might have to grab yourself a translator) that the RV770 chip has it's own PCIe bridge build in and therefore won't be needing a PLX chip, or get a smaller (proprietary) one. The R700 board is smaller because of this, quite a surprise actually as R700 will probably draw more power than R680 and it will still be a shorter board.
There probably are a couple more things to mention but these are probably the most significant changes.
