Non-gaming benchmark results comparison. The combined score is measured on a 0-100 point scale.
Combined synthetic benchmark score
This is our combined benchmark score. We are regularly improving our combining algorithms, but if you find some perceived inconsistencies, feel free to speak up in comments section, we usually fix problems quickly.
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.
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.
