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: The ATI Radeon HD 5830 1GB graphics card performed at 75FPS at 1920×1200 and was 21% faster than the Radeon HD 5770 graphics card.
