FurMark 1.7.0
FurMark is a very intensive OpenGL benchmark that uses fur renderingalgorithms to measure the performance of the graphics card. Furrendering is especially adapted to overheat the GPU and that's whyFurMark is also a perfect stability and stress test tool (also calledGPU burner) for the graphics card.
The benchmark was rendered in full screen mode with no AA enabled on both video cards.
Benchmark Results: The Sapphire Radeon HD 5870 Vapor-X was 3 FPS faster than a reference ATI Radeon HD 5870 in the Furmark benchmark test.
