Which GPU should you choose for Blender?
RTX 3080 Ti is the stronger Blender rendering pick here based on benchmark score.
Cycles rendering performance
RTX 3080 Ti leads by 63.8% in the Renderjuice Blender benchmark model (4,843 vs 2,956). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
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 ratings 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.
Is the upgrade worthwhile?
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.
Comparison summary
RTX 3080 Ti leads the Blender benchmark score by 63.8%.
Fastest in Cycles: RTX 3080 Ti 64% faster than RTX 3070.
Most VRAM: RTX 3080 Ti 50% more VRAM than RTX 3070.
Lowest power draw: RTX 3070 37% lower rating than RTX 3080 Ti.
Cheapest: RTX 3070 50% cheaper than RTX 3080 Ti.
Best value for money: RTX 3070 23% better value than RTX 3080 Ti.
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.
