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 4.3GHz. The processor Vcore was increased to 1.3975V in the mainboard BIOS:
The 6 GB of system DDR3 memory worked at 1.72 GHz frequency with 8-8-8-16_1T timings and 1.64V voltage. Turbo Boost and Hyper-Threading technologies were disabled during our test session.
The test session started on April 16, 2011. All tests were performed in Microsoft Windows 7 Ultimate x64 with all critical updates as of that date and the following drivers:
- Intel Chipset Drivers 184.108.40.2063 alpha for the mainboard chipset;
- DirectX End-User Runtimes from November 30, 2010;
- Catalyst 11.4 Beta (04/15/2011) drivers for AMD based graphics cards;
- Nvidia GeForce/ION 270.51 WHQL (03/30/2011) driver for Nvidia based graphics cards.
The graphics cards were tested only in one resolution: 1920x1080. In our opinion, taking into account the current price of monitors supporting this resolution and an only 6~8 % performance difference between this resolution and 1680x1050, it doesn’t make much sense to add the latter to the tests. And higher resolutions aren’t for entry-level or mainstream graphics cards, anyway.
The tests were performed in two image quality modes: “Quality+AF16x” – default texturing quality with enabled 16x anisotropic filtering and “Quality+ AF16x+AA4(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 Panel of Catalyst and GeForce/ION drivers. There were no other changes in the driver settings.
The benchmarking games and applications list has two new names on it. They are Warhammer 40,000 Dawn of War II: Retribution and Crysis 2. Besides, some games were updated with new patches, and we recorded a new demo-scene in Left 4 Dead 2. As a result, the list had two popular semi-synthetic benchmarking suites, one technical demo and 19 games of various genres. Here is the complete list of tests used with the settings (all games listed in their release order):
- 3DMark Vantage (DirectX 10) – v220.127.116.11, Performance and Extreme profiles (basic tests only);
- 3DMark 2011 (DirectX 11) – version 18.104.22.168, Performance and Extreme profiles;
- Unigine Heaven Demo (DirectX 11) – version 2.1, maximum graphics quality settings, tessellation at “extreme”, AF16x, 1280x1024 resolution without AA and 1920x1080 resolution with AA 4x;
- Crysis (DirectX 10) – game version 1.2.1, “Very High” settings profile, two runs of “Assault harbor” test from Crysis Benchmark Tool version 22.214.171.124;

- Resident Evil 5 (DirectX 10.1) – version 1.2, variable benchmark with maximum graphics quality settings without motion blur, we took AVG values from the third scene for further analysis, because it was the most resource-hungry;
- S.T.A.L.K.E.R.: Call of Pripyat (DirectX 11) – version 1.6.02, Enhanced Dynamic DX11 Lighting profile with all parameters manually set at their maximums, we used our custom cop03 demo on the Backwater map;

- Metro 2033: The Last Refuge (DirectX 10/11) - version 1.2, maximum graphics quality settings, official benchmark, “High” image quality settings; tesselation, DOF and MSAA4x disabled; AAA aliasing enabled, two consecutive runs of the “Frontline” scene;

- 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;
- Mafia 2 (DirectX 11) – version 18.104.22.168, maximum graphics quality settings, two runs of the built-in benchmark;
- Sid Meier’s Civilization V (DirectX 11) – version 22.214.171.124, maximum graphics quality settings, two runs of the “diplomatic” benchmark including five heaviest scenes;
- F1 2010 (DirectX 11) – version 1.01, built-in benchmark at Ultra quality settings including one lap on the “Silverstone” track;
- 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;

- Warhammer 40,000 Dawn of War II: Retribution (DirectX 10.1) – version 126.96.36.19955, maximum graphics quality settings, activated shadows, two runs of the built-in test scene.
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.
