Although it give you no idea what to expect for actual in game performance, there is still no better way to compare performance from card to card than 3DMark. In our case we run both 3DMark Vantage and 3DMark 11, on top of that each is run in performance then again on high/extreme. In all four cases our results for the Sapphire HD 7770 Vapor-X all fall in about the same. We saw numbers slightly below the R7770 from XFX and a little farther from the Overclocked HD 7770 saw looked at from Sapphire previously. What is the difference between those two cards and this one? The overclock. The Sapphire card had a 50MHz core speed difference than the Vapor-X, and the XFX although close, had a noticeably higher memory clock. I’m not sure why Sapphire went with a slightly lower overclock this time around considering the improved cooler, but the two cards give you a good idea what to expect with a slight overclock on this card.
