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 the video cards.
Benchmark Results: Furmark is a benchmark that tries to get your card as hot as it can while trying to render a huge fuzzy donut. Easy enough, you would think; nope, not here. If you didn’t know better you would think Furmark was trying to kill your card. The Sapphire Radeon HD 6850 Toxic had no problem pumping out some decent frame rates. All of the 6850’s we have looked at have scored within a few frames of each other.
