Performance in Synthetic and Semi-Synthetic Benchmarks

Futuremark 3DMark Vantage

We minimize the CPU’s influence by using the Extreme profile (1920x1200, 4x FSAA and anisotropic filtering). We also publish the results of the individual tests across all resolutions.

Top-end graphics subsystems are often used to setting new records in synthetic benchmarks. A 3DMark Vantage score of 10,000 points used to be considered high just some time ago, but now the ASUS Radeon HD 6990+6970 tandem stops at 25,000 points and is even overtaken by the 3-way GeForce GTX 570 SLI.

3DMark Vantage shows different compatibility with multi-GPU technologies. Nvidia’s trio doesn’t enjoy a large advantage over the 2-way GeForce GTX 580 SLI or over the GeForce GTX 590. In the AMD camp, adding the Radeon HD 6970 to the ASUS EAH6990/3DI4S/4GD5 increases the latter’s performance by almost 50%, and the resulting 3-way CrossFireX tandem wins the test at high resolutions.

Futuremark 3DMark11

We use the Extreme profile here. As opposed to 3DMark Vantage, this profile has a resolution of 1920x1080 pixels.

3DMark11 prefers the graphics architecture with higher computing resources which is the 3-way CrossFireX configuration. The advantage over the 3-way GeForce GTX 570 SLI is less than 100 points, yet that's enough to claim victory in this test.

Tom Clancy’s H.A.W.X. 2 Preview Benchmark

This benchmark makes wide use of tessellation to render the surface of the earth. The number of polygons per one frame can be as high as 1.5 million!

This test illustrates the importance of the graphics driver. The Antilles+Cayman duo copes with the test well and challenges the Nvidia-based products which have been traditionally strong here. If you take note of the performance of the SLI configuration, you can see that it fails due to the ForceWare driver.

Unigine Heaven 2.5 benchmark

We use Normal tessellation in this test.

Tessellation is crucial in this test, so Nvidia’s product comes out the winner due to its better tessellation subunit. The 3-way GeForce GTX 570 SLI only wins at 1600x900, though. The ASUS Radeon HD 6990+6970 tandem catches up with the leader and matches its performance at the higher resolutions.
