Performance recapAlthough individual game results are worth looking at, we have calculated a performance index based on all tests with the same weight for each game. Mafia II is included with the scores obtained without GPU PhysX effects.
We attributed an index of 100 to the GeForce GTX 460 1 GB at 1680x1050:

It’s interesting to see that AMD and NVIDIA are on an equal footing in several of the games: GeForce GTX 460 1 GB and Radeon HD 6850, GeForce GTS 450 and Radeon HD 5750… and GeForce GTX 550 Ti and Radeon HD 5770.
Another thing that comes out in this analysis is a trend we’ve noted with the GeForce 400s and 500s: they suffer a little less when antialiasing is enabled, but a little more at higher resolutions, which is explained by the reduced fillrate given by their internal architecture.
With a 10% performance advantage over the Radeon HD 5770, the Radeon HD 6790 is positioned between the GeForce GTX 550 Ti and GTX 460 SE. It is however further down on the Radeon HD 6850 which gives between 17% and 22% better performance, the biggest differences coming with antialiasing activated.
