Besides the two above discussed new products, we also included three graphics cards on Nvidia GPUs: MSI N580GTX Lightning Xtreme Edition, Gainward GeForce GTX 570 and MSI N560GTX-Ti Twin Frozr II/OC, which frequencies were adjusted to match the reference ones.
In our opinion, adding these five graphics accelerators will allow us not only to perform fully fledged performance analysis for the new GeForce GTX 560 Ti 448 Cores cars, but also draw some end-of-year conclusions about the graphics cards performance in the $250+ price segment.
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 25x and “Load-Line Calibration” (Level 2) enabled to 4.5 GHz. The processor Vcore was increased to 1.46875 V in the mainboard BIOS:
The 6 GB of system DDR3 memory worked at 1.44 GHz frequency with 7-7-7-16_1T timings and 1.5V voltage. Turbo Boost and Hyper-Threading technologies were disabled during our test session.
The test session started on December 12, 2011. 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 188.8.131.521 Alpha from 11.22.2011 for the mainboard chipset;
- DirectX End-User Runtimes libraries from November 30, 2010;
- Nvidia GeForce 290.36 beta driver from 11.28.2011 for Nvidia based graphics cards;
- AMD Catalyst 12.1 Preview driver from 12.12.2011 for AMD based graphics cards.
The graphics cards were tested in one today’s most popular resolution - 1920x1080. 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+MSAA4(8)x” with enabled 16x anisotropic filtering and full screen 4x anti-aliasing (MSAA) or 8x if the average framerate was high enough for comfortable gaming experience. We enabled anisotropic filtering and full-screen anti-aliasing from the game settings or configuration files. If the corresponding options were missing, we changed these settings in the Control Panels of Catalyst and GeForce drivers. There were no other changes in the driver settings.
The list of games and applications used in this test session includes two popular semi-synthetic benchmarking suites, one technical demo and 14 games of various genres:
- 3DMark Vantage (DirectX 10) – version 184.108.40.206, Performance and Extreme profiles (only basic tests);

- Just Cause 2 (DirectX 11) - version 22.214.171.124, maximum quality settings, Background Blur and GPU Water Simulation enabled, two consecutive runs of the “Dark Tower” demo;
- Aliens vs. Predator (2010) (DirectX 11) – Texture Quality “Very High”, Shadow Quality “High”, SSAO On, two test runs in each resolution;
- Lost Planet 2 (DirectX 11) – version 1.0, maximum graphics quality settings, motion blur enabled, performance test “B” (average in all three scenes);
- StarCraft 2: Wings of Liberty (DirectX 11) – version 1.0, all image quality settings at “Ultra”, Physics “Ultra”, reflections On, two 2-minute runs of our own jt1 demo;
- Sid Meier’s Civilization V (DirectX 11) – version 126.96.36.1998, maximum graphics quality settings, two runs of the “diplomatic” benchmark including five heaviest scenes;
- Tom Clancy's H.A.W.X. 2 (DirectX 11) – version 1.04, maximum graphics quality settings, shadows On, tessellation Off (not available on Radeon), two runs of the test scene;
- Total War: Shogun 2 (DirectX 11) – version 2.0, built in benchmark (Sekigahara battle) at maximum graphics quality settings;
- DiRT 3 (DirectX 11) – version 1.2, built-in benchmark at maximum graphics quality settings on the “Aspen” track;
- World of Planes (DirectX 9) – alpha-version (from 08.19.2011), maximum image quality settings, one test run;
- Hard Reset Demo (DirectX 9) – benchmark built into the demo version with Ultra image quality settings, one test run;
- Batman: Arkham City (DirectX 11) – version 1.2, maximum graphics quality settings, physics disabled, two sequential runs of the benchmark built into the game.
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.
