Passmark

This is the most ubiquitous GPU benchmark. It gives the graphics card a thorough evaluation under various types of load, providing four separate benchmarks for Direct3D versions 9, 10, 11 and 12 (the last being done in 4K resolution if possible), and few more tests engaging DirectCompute capabilities.

3DMark Fire Strike Graphics

Fire Strike is a DirectX 11 benchmark for gaming PCs. It features two separate tests displaying a fight between a humanoid and a fiery creature made of lava. Using 1920x1080 resolution, Fire Strike shows off some realistic graphics and is quite taxing on hardware.

Unigine Heaven 4.0

This is an old DirectX 11 benchmark, a newer version of Unigine 3.0 with relatively small differences. It displays a fantasy medieval town sprawling over several flying islands. The benchmark is still sometimes used, despite its significant age, as it was released back in 2013.
