PowerColor Devil 13 Radeon HD 7990 - Speak of the Devil

Batman: Arkham City & Dirt 3 Results

Batman: Arkham City Results

No surprise here, Arkham City is optimized for NVIDIA PhysX and as expected, both NVIDIA setups far outperformed the Devil 13 and HD 7970 CrossFireX setup. What's weird is the fact that the dual-GPU counterparts from AMD were no better than a single Radeon HD 7970 GHz edition card. Clearly, something wasn't optimized properly on the AMD cards.

Dirt 3 Results

While all of our cards easily handled Dirt 3, the Devil 13 still outperformed both NVIDIA competitors by about 8%. It also outperformed the HD 7970 CrossFireX setup by about 3.5% at 2560 x 1600 resolution. It should be noted however that Dirt 3 is AMD optimized, and that this is the one test where updated drivers seemed to make quite a big difference.
