gpumagick.com is a website that hosts score databases of
FurMark2 and
MadGPU utilities.
MadGPU is a graphics card utility that can be used to stress test a GPU or to test the
OpenGL or
Vulkan support via several graphics tests. It is also a handly
graphics benchmark
with online scores. MadGPU is the successor of
GpuTest, a graphics card utility stopped in 2014 (and that is still used today!).
FurMark2 and MadGPU are both based on the
GeeXLab engine and are available on Windows and Linux (x86_64 and arm64) platforms.
MadGPU is currently in development but you can already test it by downloading
FurMark2, a derivative project.
FurMark2 can be seen as a limited version of GPU Magick with only one graphics test: FurMark!
