The final siliconWe got news that DAAMIT actually won't change the R600 silicon. R600 will stay the same and the driver, a PCB design and a clock were the factor that pushed the launch.
The chip is fine, at least one good news from DAAMIT. But still the fans won't benefit from it as the cards got delayed to some point in May.
The chips will be clocked differently than the originally planned but clocks won't be announced until some point in April. The beta cards are running, with an NDA you might actually see one sooner than expected.
