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 3090 is the stronger Blender rendering pick here based on benchmark score.

Blender render speed

RTX 3090 leads by 21.0% in the Renderjuice Blender benchmark model (5,825 vs 4,812). For render-time-first decisions, that is the card to prioritize.

VRAM and scene headroom

RTX 3090 has more scene headroom with 24 GB of VRAM versus 10 GB on RTX 3080. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.

Power and cooling

RTX 3080 is the lower-power option at 320 W TDP, compared with 350 W for RTX 3090. If render speed is close, that can make RTX 3080 easier to cool and run quietly.

Upgrade decision

RTX 3090 is the straightforward performance pick, while RTX 3080 needs a price, power, availability, or compatibility advantage to make more sense.

Quick take on RTX 3080 vs RTX 3090

RTX 3090 leads the Blender benchmark score by 21.0%.

Fastest in Blender: RTX 3090 5,825.23 score.

Most VRAM: RTX 3090 24 GB.

Lowest power draw: RTX 3080 320 W TDP.

RTX 3080 has 10 GB of VRAM, while RTX 3090 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.
