ATI is working hard to ship a new RV670 A12 revision to the market. All current Radeon 3870, 3850 and 3870 X2 cards are A11 silicon-based and the new silicon should definitely improve things here and there.

The A12 revision definitely sounds like higher clocks are possible, as we are sure that there is still some space for optimization. ATI now works at a bit more relaxed deadline, as it has a good chip to compete with G92 generation, but again if DAAMIT pushes a bit more it might even win.

These chips are expected in mid-Q2 timeframe.
