AMD Cayman info (or rumor)

i dont think the 6970 will be much faster (if ever...) than the 580.. the "crude algebra" which was pointed before, gives us 1920/4=480SPs*900mhz / 512SPs*772 = 1.0929 ~+9.3% theoretical advantage, if add the rumor about having trouble for target frequencies, and settle for 850mhz.. then its 480*850 / 512*772 = 1.0322 or a mere 3.2% theoretical advantage.. which in actual performance bonus will be negligible. (In fact if comes out with 850mhz clock i strongly believe it may be a tiny slower though..)

only problem with your math is that GTX580 shaders run at over 1.5ghz
