OCCT 3.1.0 shows HD4870/4890 design flaw - they can't handle the new GPU test !

Do the numbers 1.2 TFLOPS for a 4870 and 933 GFLOPS for a GTX 280 mean anything to you? Perhaps this OCCT benchmark is pushing somewhere close to 1.2 TFLOPS?

I have shown that those numbers don't make sense. Nvidia cards still should be performing better then they do. With the numbers from a GTX285, they are not using the MUL to it's full potential, one of the things that was supposedly "fixed" from G80. It is not performing at the 1.06TFlop(MADD+MUL) level nor at the 708GFlop(MADD) level but an inbetween. Basically the MUL is only being exploited ~45% of the time.

Sure, it is loading the cards but it is not exploiting all the shaders that the G200 has to offer.

People are complaining that they cannot fully utilize their RV770 cards, since some have to be downclocked to be stable in OCCT.
The flipside is that you are also not getting full advantage of all that G200 has to offer with the results of OCCT.
When using a G200 you are only receiving ~82% of the performance.
