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 is the stronger Blender rendering pick here, and both cards have the same VRAM capacity.

Blender render speed

RTX 4090 leads by 100.6% in the Renderjuice Blender benchmark model (11,688 vs 5,825). For render-time-first decisions, that is the card to prioritize.

VRAM and scene headroom

Both cards have 24 GB of VRAM, so the decision is less about scene capacity and more about render speed, architecture, power draw, and price.

Power and cooling

RTX 3090 is the lower-power option at 350 W TDP, compared with 450 W for RTX 4090. If render speed is close, that can make RTX 3090 easier to cool and run quietly.

Upgrade decision

RTX 4090 is both the newer and faster Blender rendering choice here. The main reason to choose RTX 3090 would be price, availability, existing ownership, or a specific workstation requirement.

Quick take on RTX 3090 vs RTX 4090

RTX 4090 leads the Blender benchmark score by 100.6%.

Fastest in Blender: RTX 4090 11,687.5 score.

Lowest power draw: RTX 3090 350 W TDP.

Both GPUs ship with 24 GB of VRAM, so the tradeoff is more about speed, architecture, and efficiency than memory capacity.

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.
