Still some difference present on the same RPM's:
Clock rates are higher across the board, as you'd expect after increasing cooling capacity. AMD's own press board now averages 944 MHz, up from 917 MHz. Asus' troubled retail card settles at 863 MHz. Meanwhile, Sapphire crests 906 MHz in our test, on average.
Anyway, if the percent of unlockable cards will drop to zero in next ~2 months, rescreening theory might be true.
Unlock news are in every PC-related media now. If it was only Powercolor that can be unlocked, I'v bet it's their marketing trick, spend a hundred(s) of 290X chips to get a strong trail of raised brand sales in next several months. But that becomes really doubtful with some (most?) of XFX being also unlockable.
