AMD Radeon HD 6990 4GB Dual GPU Video Card Review

3DMark 11

3DMark 11 is the latest version of the worlds most popular benchmark for measuring the 3D graphics performance of gaming PCs. 3DMark 11 uses a native DirectX 11 engine designed to make extensive use of all the new features in DirectX 11, including tessellation, compute shaders and multi-threading.

Since Futuremark has recently released 3DMark11 we decided to run the benchmark at both performance and extreme presets to see how our hardware will run.

3DMark 11 Performance Benchmark Results:

Much like many of our benchmarks today, the AMD Radeon HD 6990 fell short of the performance of a pair of AMD Radeon HD 6970’s in CrossfireX in FutureMark 3DMark 11. Running the Extreme Preset the AMD Radeon HD 6990 was ~5.3% behind the AMD Radeon HD 6970’s for the overall score as well as the GPU score. The performance preset shows a much closer margin for the overall score, only 77 3DMarks or .8%. The GPU score tells us a different tale though. The Radeon HD 6970’s gave us a GPU score of 9737, while the AMD Radeon HD 6990 gives us a GPU score of 9317. That’s a difference of 420 3DMarks or 4.3%
