We will compare the new card with the dual-processor solutions AMD Radeon HD 7990 2x3GB and Nvidia GeForce GTX 690 2x2GB working at their default clock rates.
We will also include the two fastest single-processor cards AMD Radeon R9 290X 4GB (at its default clock rates) and Zotac GeForce GTX Titan Black 6GB (at the default clock rates and in overclocked mode).
The Zotac is overclocked to 1064-1155/8120 MHz. It is priced like the dual-processor Nvidia GeForce GTX 690 ($999), so we want to know if the current single-processor flagship can catch up with the dual-processor flagship card of the previous generation. The Power Limit is set at its maximum for each graphics card.
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 1.385 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 – 126.96.36.1996 WHQL dated 21.09.2013
- DirectX End-User Runtimes, dated 30 November 2010
- AMD Catalyst 14.6 Beta (188.8.131.52) dated 27.05.2014
- Nvidia GeForce 337.88 WHQL dated 26.05.2014
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 V-Sync there. There were no other changes in the driver settings.
The graphics cards were tested in two benchmarks and 14 games updated to the latest versions.

- Company of Heroes 2 (DirectX 11) version 220.127.116.1153: two consecutive runs of the integrated benchmark at maximum image quality and physics effects settings.
- Total War: Rome II (DirectX 11) version 18.104.22.168: Extreme quality, V-Sync disabled, SSAA enabled, two consecutive runs of the integrated benchmark.

- Thief (DirectX 11) version 1.5 build 4158.5: Maximum visual quality settings, Parallax Occlusion Mapping and Tessellation enabled, a double run of the in-game benchmark with the Mantle API enabled for AMD-based cards.
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.
