FurMark

FurMark is a very intensive GPU stress test. It renders a demanding 3D scene that pushes the graphics card to its limits, which is used to check the stability, cooling and power delivery of a GPU, for example after overclocking or when building a system.

FurMark 2, the successor of FurMark 1, runs on Windows and Linux (32-bit and 64-bit) and is also a quick OpenGL and Vulkan graphics benchmark with online scores. It has improved command-line support and is built with GeeXLab. FurMark 1, for 32-bit Windows, is still maintained.

FurMark is developed by Geeks3D and is free to use.
