Rendering performance

Median score · higher is better

Three-scene Blender rendering throughput. Versions, operating systems and rendering backends remain separate. This is not a gaming score.

Community submissions; cooling, power limits and system configuration can affect results.

Graphics & compute benchmarks

Archived cohort medians

GFXBench, GLBenchmark and CompuBench results retain the tested system, API, operating system and resolution. Offscreen tests fix the render resolution; onscreen results also reflect the display workload. These historical submissions do not establish performance in current games.
