Besides the above discussed graphics cards we also added three more products to our review. The first one is MSI GeForce GTX 660 2 GB and it is included for comparison against GeForce GTX 650 Ti, in order to determine how big of a gap there is between them. The second card is Sapphire Radeon HD 7850 2 GB, which retails for more than GeForce GTX 650 Ti 2 GB, but the price difference is really small, so we regard it as a potential competitor to GeForce GTX 650 Ti 2 GB. And finally, the third graphics card is AMD Radeon HD 7770 1 GB, which is priced precisely between GeForce GT 640 and GeForce GTX 650 Ti 1 GB, so it makes sense to use it, too.
As usual, 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 9-10-10-28 timings and 1.65V voltage.
The test session started on December 25, 2012. 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 188.8.131.529 WHQL from 12/08/2012 for the mainboard chipset;
- DirectX End-User Runtimes libraries from November 30, 2010;
- AMD Catalyst 12.11 beta (9.010.8) driver from 12/02/2012 + Catalyst Application Profiles 12.11 (CAP2) for AMD based graphics cards;
- Nvidia GeForce 310.70 beta driver from 12.04.2012 for Nvidia based graphics cards.
For our tests of the GeForce GTX 650 Ti we decided to stick only to one single resolution – 1920x1080 pixels, because the monitors supporting this resolution are currently selling for less than some GeForce GTX 650 Ti graphics cards from this roundup. This series of graphics is not fit for higher resolutions than that because of their insufficient performance, and any resolutions below 1920x1080 should be absolutely no problem for all testing participants.
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.

- Hitman: Absolution (DirectX 11) – version 1.0, built-in test with Ultra image quality settings, with enabled tessellation, FXAA and global lighting.
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.
