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 4080 is the stronger Blender rendering pick here based on benchmark score.

Blender render speed

RTX 4080 leads by 132.6% in the Renderjuice Blender benchmark model (8,733 vs 3,755). For render-time-first decisions, that is the card to prioritize.

VRAM and scene headroom

RTX 4080 has more scene headroom with 16 GB of VRAM versus 8 GB on RTX 3070 Ti. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.

Power and cooling

RTX 3070 Ti is the lower-power option at 290 W TDP, compared with 320 W for RTX 4080. If render speed is close, that can make RTX 3070 Ti easier to cool and run quietly.

Upgrade decision

RTX 4080 is both the newer and faster Blender rendering choice here. The main reason to choose RTX 3070 Ti would be price, availability, existing ownership, or a specific workstation requirement.

Quick take on RTX 3070 Ti vs RTX 4080

RTX 4080 leads the Blender benchmark score by 132.6%.

Fastest in Blender: RTX 4080 8,733.36 score.

Most VRAM: RTX 4080 16 GB.

Lowest power draw: RTX 3070 Ti 290 W TDP.

RTX 3070 Ti has 8 GB of VRAM, while RTX 4080 has 16 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.
