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 56.2% in the Renderjuice Blender benchmark model (8,733 vs 5,592). 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 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 4080 is the lower-power option at 320 W TDP, compared with 350 W for RTX 3080 Ti. If render speed is close, that can make RTX 4080 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 3080 Ti would be price, availability, existing ownership, or a specific workstation requirement.
Quick take on RTX 3080 Ti vs RTX 4080
RTX 4080 leads the Blender benchmark score by 56.2%.
Fastest in Blender: RTX 4080 8,733.36 score.
Most VRAM: RTX 4080 16 GB.
Lowest power draw: RTX 4080 320 W TDP.
RTX 3080 Ti has 12 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.
