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 3080 12 GB
8.2 / 10 Expert Rating
A genuinely better RTX 3080 - the extra VRAM and bandwidth make it the version to look for on the secondhand market over the original 10GB card.
AMD Sapphire Nitro+ Radeon RX 6800
8 / 10 Expert Rating
A solid high-end pick if its price and 16GB VRAM allocation match your target resolution.
