Benchmarks Real world tests of Radeon HD 7850 vs GeForce GTX 660

Passmark Industry standard benchmark for overall graphics card performance

3DMark 11, as the name might probably suggest, makes use of the Microsoft DirectX 11 API and puts every feature of it at its disposal to use, creating astonishingly realistic visuals.

3DMark Vantage (Texture Fill) Industry standard benchmark that tests DirectX performance

Crysis: Warhead (2013) 1920x1080 - Enthusiast Quality + 4xAA

Radeon HD 7850
38.9 fps
GeForce GTX 660
39.6 fps
The game was by far the most hyped and anticipated game in 2007, and forums were full of "Can my system run Crysis?

Batman: Arkham City 1920x1200 - Extreme quality + FXAA-HIGH

Batman: Arkham City uses the same Unreal Engine by Epic as Batman: Arkham Asylum does, but, it has, thanks to the engine's modularity, been overhauled and outfitted with the latest technologies, including a graphics engine that takes advantage of DirectX 11.

We see very good overclocking potential for GPU clock, which is the best of all HD 7850 cards that we've reviewed so far.

when you talk about gaming, nVIDIA is the best, no doubt!
But it really does not matter because the 660 overclocked will again pass it up. The price of the 660 is also better than the price of the 7850, So you would be dumb to by the 7850 unless you could get it for $150. But really the 7850 is not to much faster than the 650 Ti, I am going to replace my 650 Ti with a 660. Great prices on them now
HD 7850 is better for gaming.
and GTX 660 has dropped its price to 180 USD...
660 wins stock 7850 wins when OC'd
