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 4090 vs RTX 5080
RTX 4090 leads the Blender benchmark score by 28.1%.
Fastest in Blender: RTX 4090 11,697.62 score.
Most VRAM: RTX 4090 24 gb.
Lowest power draw: RTX 5080 360 w tdp.
RTX 4090 has 24 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.
