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 A4500
7.1 / 10 Expert Rating
A solid, unglamorous mainstream workstation card - good value on the refurbished market for CAD work that doesn't need cutting-edge ray tracing or AI performance.
AMD Sapphire Pulse Radeon RX 7700 XT
7 / 10 Expert Rating
A solid mainstream pick if its price and 12GB VRAM allocation match your target resolution.
