The Zotac card will be compared with the top-end single-GPU reference cards Nvidia GeForce GTX 780 Ti ($699) and AMD Radeon R9 290X ($649) working at their standard clock rates:
We also include EVGA's original GeForce GTX 780 Superclocked ACX 3GB (at the reference GTX 780 clock rates as well as with maximum overclocking) and a reference AMD Radeon R9 290 4GB (without overclocking).
In order to lower the dependence of the graphics cards’ performance on the overall platform speed, we overclocked our 32nm six-core CPU to 4.8 GHz by setting its frequency multiplier at x48 and enabling Load-Line Calibration. The CPU voltage was increased to 1.38 volts in the mainboard’s BIOS:
Hyper-Threading was turned on. We used 32 GB of system memory at 2.133 GHz with timings of 9-11-11-20_CR1 and voltage of 1.6125 volts.
The testbed ran Microsoft Windows 7 Ultimate x64 SP1 with all critical updates installed. We used the following drivers:
- Intel Chipset Drivers – 22.214.171.1246 WHQL dated 21.09.2013
- DirectX End-User Runtimes, dated 30 November 2010
- AMD Catalyst 13.12 WHQL (126.96.36.199) dated 18.12.2013
- GeForce 331.93 Beta dated 27.11.2013
We benchmarked the graphics cards’ performance at two display resolutions: 1920x1080 and 2560x1440 pixels. There were two visual quality modes: “Quality+AF16x” means the default texturing quality in the drivers + 16x anisotropic filtering whereas “Quality+ AF16x+MSAA 4x(8x)” means 16x anisotropic filtering and 4x or 8x antialiasing. In some games we use antialiasing algorithms other than MSAA as indicated below and in the diagrams. We enabled anisotropic filtering and full-screen antialiasing from the game’s menu. If the corresponding options were missing, we changed these settings in the Control Panels of the Catalyst and GeForce drivers. We also disabled Vsync there. There were no other changes in the driver settings.
The graphics cards were tested in 2 benchmarks and 13 games updated to the latest versions.
- 3DMark (2013) (DirectX 9/11) version 188.8.131.52: Cloud Gate, Fire Strike and Fire Strike Extreme scenes.

- Total War: SHOGUN 2 – Fall of the Samurai (DirectX 11) version 1.1.0: integrated benchmark (the Sekigahara battle) with maximum visual quality settings and 8x MSAA.
- Sniper Elite V2 Benchmark (DirectX 11) version 1.05: Adrenaline Sniper Elite V2 Benchmark Tool v184.108.40.206 BETA with maximum graphics quality settings (“Ultra” profile), Advanced Shadows: HIGH, Ambient Occlusion: ON, Stereo 3D: OFF, Supersampling: OFF, two sequential runs of the test.
- Sleeping Dogs (DirectX 11) version 1.5: Adrenaline Sleeping Dogs Benchmark Tool v220.127.116.11 with maximum image quality settings, Hi-Res Textures pack installed, FPS Limiter and V-Sync disabled, two consecutive runs of the built-in benchmark with quality antialiasing at Normal and Extreme levels.

- Tomb Raider (2013) (DirectX 11) version 1.1.748.0: Adrenaline Benchmark Tool, “Ultra” image quality settings, V-Sync disabled, FXAA and 2x SSAA antialiasing enabled, TessFX technology activated, two consecutive runs of the in-game benchmark.
- BioShock Infinite (DirectX 11) version 22.214.171.12418: Adrenaline Action Benchmark Tool with “Ultra” and “Ultra+DOF” quality settings, two consecutive runs of the in-game benchmark.
- Metro: Last Light (DirectX 11) version 126.96.36.199: we used the built-in benchmark for two consecutive runs of the D6 scene. All image quality and tessellation settings were at “Very High”, Advanced PhysX technology enabled, with and without SSAA antialiasing.
- GRID 2 (DirectX 11) version 188.8.131.5279: we used the built-in benchmark, the visual quality settings were all at their maximums, the tests ran with and without MSAA 8x antialiasing with eight cars on the Chicago track.
- Company of Heroes 2 (DirectX 11) version 184.108.40.20611: two consecutive runs of the integrated benchmark at maximum image quality and physics effects settings.
- Total War: Rome II (DirectX 11) version 1.8.0 build 8891.481024: Extreme quality, V-Sync disabled, SSAA enabled, two consecutive runs of the integrated benchmark.

- Battlefield 4 (DirectX 11) version 1.4: Ultra settings, two successive runs of a scripted scene from the beginning of the “Tashgar” mission (110 seconds long).
We publish the bottom frame rate for games that report it. Each test was run twice, the final result being the best of the two if they differed by less than 1%. If we had a larger difference, we reran the test at least once again to get repeatable results.
