Benchmarks
Measured results, not specifications. Percentages are the gap to the leading product in each test.
Blender Cycles (GPU)
Blender 4.5, Blender Open Data (CC0). Median of monster + junkshop + classroom, combined samples/min.
Blender renders 3D scenes by tracing light through them, which loads every shader unit on the card at once. The score measures sustained render throughput, so it tells you what a card does in Cycles and similar renderers rather than what it does in a game. Figures come from Blender's Open Data project, which places no restriction on reuse, and we publish the median of every submission for that card on the same Blender version.
