Benchmark comparison

Estimated render times for standard Blender benchmark scenes. Lower is faster.

RTX 4080 SUPER
RTX 4090

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 4080 SUPER vs RTX 4090

RTX 4090 leads the Blender benchmark score by 38.8%.

Fastest in Blender: RTX 4090 11,697.62 score.

Most VRAM: RTX 4090 24 gb.

Lowest power draw: RTX 4080 SUPER 320 w tdp.

RTX 4080 SUPER has 16 GB of VRAM, while RTX 4090 has 24 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.
