Of all graphics cards mentioned above only Asus card has higher nominal frequencies that is why we decided to adjust them to the reference level for GeForce GTX 680 based products for the purity of the experiment:
In order to lower the dependence of the graphics cards performance on the overall platform speed, I overclocked our 32 nm six-core CPU with the multiplier set at 37x, BCLK frequency set at 125 MHz and “Load-Line Calibration” enabled to 4.625 GHz. The processor Vcore was increased to 1.49 V in the mainboard BIOS:
Hyper-Threading technology was enabled. 16 GB of system DDR3 memory worked at 2 GHz frequency with 9-11-10-28 timings and 1.65V voltage.
The test session started on February 24, 2013. All tests were performed in Microsoft Windows 7 Ultimate x64 SP1 with all critical updates as of that date and the following drivers:
- Intel Chipset Drivers 22.214.171.1244 WHQL from 02/07/2013 for the mainboard chipset;
- DirectX End-User Runtimes libraries from November 30, 2010;
- AMD Catalyst 13.2 Beta 6 (126.96.36.199) driver from 02/18/2013 + Catalyst Application Profiles 12.11 (CAP2) for AMD based graphics cards;
- Nvidia GeForce 314.09 WHQL driver from 02/21/2013 for GeForce GTX TITAN and GeForce 314.07 WHQL from 02/18/2013 for GeForce GTX 690 and GTX 680 based graphics cards.
We ran our tests in the following two resolutions: 1920x1080 and 2560x1440. The tests were performed in two image quality modes: “Quality+AF16x” – default texturing quality in the drivers with enabled 16x anisotropic filtering and “Quality+ AF16x+MSAA 4(8)x” with enabled 16x anisotropic filtering and full screen 4x or 8x antialiasing if the average framerate was high enough for comfortable gaming experience. We enabled anisotropic filtering and full-screen anti-aliasing from the game settings. If the corresponding options were missing, we changed these settings in the Control Panels of Catalyst and GeForce drivers. We also disabled Vsync there. There were no other changes in the driver settings.
The list of games and applications used in this test session has been once again expanded and updated. Now we include the new 3DMark (2013), the latest version of the Heaven benchmark and the newest and very beautiful Valley benchmark. Moreover, we also added such new gaming titles as Resident Evil 6, Crysis 3 and Tomb Raider (2013). As a result, the testing suite no includes two semi-synthetic benchmarking suites, two demo-scenes and 14 latest games of various genres with all updates installed as of the beginning of the test session date:

If the game allowed recording the minimal fps readings, they were also added to the charts. We ran each game test or benchmark twice and took the best result for the diagrams, but only if the difference between them didn’t exceed 1%. If it did exceed 1%, we ran the tests at least one more time to achieve repeatability of results.
