Notes
We've gone the whole nine yards and tested, from scratch, seven graphics cards for this review, all on the latest drivers. The in-game settings have been downgraded a touch from those used in our high-end suite; there's little point in hammering mid-range cards with unnecessary load. We've run at the lower 1,680x1,050 resolution, as well.
The comparison cards encompass interesting choices. From NVIDIA's side it makes sense to look at the next GPU up, GTX 660, and the GeForce GTX 550 Ti - the card ostensibly replaced by the GTX 650 Ti. From AMD, we have the Radeon HD 7770 1GB, a last-generation HD 6870, which many readers purchased for the same kind of cash as the GTX 650 Ti retails for now. Lastly, stepping it up a notch, the roughly price-comparable Radeon HD 7850 2GB is rolled in.
In the interests of fairness, any GPU vendor-specific technologies are disabled during benchmarking. For example, NVIDIA-exclusive features such as PhysX in Batman: Arkham City and the Bokeh Filter in Just Cause 2 are not enabled. Last but not least, all cards in the ensuing graphs are reference - no factory-overclocked models allowed!
