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 based on benchmark score.
Blender render speed
RTX 3080 Ti leads by 65.5% in the Renderjuice Blender benchmark model (5,592 vs 3,378). For render-time-first decisions, that is the card to prioritize.
VRAM and scene headroom
RTX 3080 Ti has more scene headroom with 12 GB of VRAM versus 8 GB on RTX 3070. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power and cooling
RTX 3070 is the lower-power option at 220 W TDP, compared with 350 W for RTX 3080 Ti. If render speed is close, that can make RTX 3070 easier to cool and run quietly.
Upgrade decision
RTX 3080 Ti is both the newer and faster Blender rendering choice here. The main reason to choose RTX 3070 would be price, availability, existing ownership, or a specific workstation requirement.
Quick take on RTX 3070 vs RTX 3080 Ti
RTX 3080 Ti leads the Blender benchmark score by 65.5%.
Fastest in Blender: RTX 3080 Ti 5,592.14 score.
Most VRAM: RTX 3080 Ti 12 GB.
Lowest power draw: RTX 3070 220 W TDP.
RTX 3070 has 8 GB of VRAM, while RTX 3080 Ti has 12 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.
