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 RTX 4000 SFF Ada Generation
7.3 / 10 Expert Rating
A useful niche card for small chassis - now a value pick against the newer RTX PRO 4000 Blackwell SFF.
NVIDIA Zotac Twin Edge OC GeForce RTX 5070
7 / 10 Expert Rating
A solid mainstream pick if its price and 12GB VRAM allocation match your target resolution.
