Benchmark comparison

Estimated seconds to render one frame of each standard Blender benchmark scene. 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.

Which GPU makes more sense?

RTX 4090 D is the stronger Blender rendering pick here based on benchmark score.

Blender render speed

RTX 4090 D leads by 90.3% in the Renderjuice Blender benchmark model (10,642 vs 5,592). For render-time-first decisions, that is the card to prioritize.

VRAM and scene headroom

RTX 4090 D has more scene headroom with 24 GB of VRAM versus 12 GB on RTX 3080 Ti. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.

Power and cooling

RTX 3080 Ti is the lower-power option at 350 W TDP, compared with 425 W for RTX 4090 D. If render speed is close, that can make RTX 3080 Ti easier to cool and run quietly.

Upgrade decision

RTX 4090 D is both the newer and faster Blender rendering choice here. The main reason to choose RTX 3080 Ti would be price, availability, existing ownership, or a specific workstation requirement.

Quick take on RTX 3080 Ti vs RTX 4090 D

RTX 4090 D leads the Blender benchmark score by 90.3%.

Fastest in Blender: RTX 4090 D 10,641.77 score.

Most VRAM: RTX 4090 D 24 GB.

Lowest power draw: RTX 3080 Ti 350 W TDP.

RTX 3080 Ti has 12 GB of VRAM, while RTX 4090 D 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.
