GTX 680 Generally Faster Than HD 7970: New Benchmarks
 

For skeptics who refuse to believe randomly-sourced bar-graphs of the GeForce GTX 680 that are starved of pictures, here is the first set of benchmarks run by a third-party (neither NVIDIA nor one of its AIC partners). This [p]reviewer from HKEPC has pictures to back his benchmarks. The GeForce GTX 680 was pitted against a Radeon HD 7970, and a previous-generation GeForce GTX 580. The test-bed consisted of an extreme-cooled Intel Core i7-3960X Extreme Edition processor (running at stock frequency), ASUS Rampage IV Extreme motherboard, 8 GB (4x 2 GB) GeIL EVO 2 DDR3-2200 MHz quad-channel memory, Corsair AX1200W PSU, and Windows 7 x64.

Benchmarks included 3DMark 11 (performance preset), Battlefield 3, Batman: Arkham City, Call of Duty: Modern Warfare 3, Lost Planet 2, and Unigine Heaven (version not mentioned, could be 1). All tests were run at a constant resolution of 1920x1080, with 8x MSAA on some tests (mentioned in the graphs).
