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 3080 Ti is the stronger Blender rendering pick here, and both cards have the same VRAM capacity.
Blender render speed
RTX 3080 Ti leads by 3.6% in the Renderjuice Blender benchmark model (5,592 vs 5,399). For render-time-first decisions, that is the card to prioritize.
VRAM and scene headroom
Both cards have 12 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 4070 is the lower-power option at 200 W TDP, compared with 350 W for RTX 3080 Ti. If render speed is close, that can make RTX 4070 easier to cool and run quietly.
Upgrade decision
RTX 4070 is newer, but RTX 3080 Ti 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 4070
RTX 3080 Ti leads the Blender benchmark score by 3.6%.
Fastest in Blender: RTX 3080 Ti 5,592.14 score.
Lowest power draw: RTX 4070 200 W TDP.
Both GPUs ship with 12 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.
