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 4.2% in the Renderjuice Blender benchmark model (5,825 vs 5,592). 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 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

Both cards list a 350 W TDP, so power draw is not the deciding spec on paper. Cooling, case airflow, and actual board partner limits still matter.

Upgrade decision

RTX 3080 Ti is newer, but RTX 3090 still leads this Blender benchmark comparison. That makes the older card worth considering when used pricing or VRAM capacity is favorable.

Quick take on RTX 3080 Ti vs RTX 3090

RTX 3090 leads the Blender benchmark score by 4.2%.

Fastest in Blender: RTX 3090 5,825.23 score.

Most VRAM: RTX 3090 24 GB.

RTX 3080 Ti has 12 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.
