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.

Verdict

NVIDIA GeForce RTX 4090

9 / 10 Expert Rating

The Ada generation's flagship, still competitive with current-gen cards thanks to a 24GB frame buffer and the full AD102 die.

NVIDIA GeForce RTX 5090

10 / 10 Expert Rating

The outright performance leader in both raster and ray tracing — but independently the worst value in the current hierarchy, demanding a flagship PSU and chassis.
