Benchmark comparison
Estimated render times for standard Blender benchmark scenes. Lower is faster.
These timings are derived from Blender Open Data benchmark medians and should be treated as comparative estimates, not guaranteed real-project render times.
Quick take on RTX 3080 vs RTX 5080
RTX 5080 leads the Blender benchmark score by 89.6%.
Fastest in Blender: RTX 5080 9,133.65 score.
Most VRAM: RTX 5080 16 gb.
Lowest power draw: RTX 3080 320 w tdp.
RTX 3080 has 10 GB of VRAM, while RTX 5080 has 16 GB, which matters when scenes, textures, or geometry get heavier.
If you are deciding between these cards for Blender, focus first on Blender benchmark score, VRAM capacity, memory bandwidth, and whether your scenes are likely to benefit more from raw speed or extra memory headroom. The comparison table above keeps those tradeoffs in one place.
