AMD Radeon HD 6990 4GB Dual GPU Video Card ReviewMon, Mar 07, 2011 - 11:00 PM
FurMark is a very intensive OpenGL benchmark that uses fur rendering algorithms to measure the performance of the graphics card. Fur rendering is especially adapted to overheat the GPU and that’s why FurMark is also a perfect stability and stress test tool (also called GPU burner) for the graphics card.
The benchmark was rendered in full screen mode with no AA enabled on both video cards.
Benchmark Results: Furmark showed the AMD Radeon HD 6990 taking the top spot of this test. It wasn’t by a small margin either. At 1280×1024 the AMD Radeon HD 6990 averaged 216 frames per second, while the pair of AMD Radeon HD 6970′s in CrossfireX averaged only 177 frames per second. Interestingly enough, a single AMD Radeon HD 6970 averaged 193 frames per second. Firing up Furmark 1.8.2 at 1920×1200 the AMD Radeon HD 6990 raced along at 175 frames per second, while the AMD Radeon HD 6970′s were cruising along at 135 frames per second and the single AMD Radeon HD 6970 kept pace at 133 frames per second.
