Which GPU should you choose for Blender?
RTX 5070 is the stronger Blender rendering pick here, and both cards have the same VRAM capacity.
Cycles rendering performance
RTX 5070 leads by 17.8% in the Renderjuice Blender benchmark model (5,792 vs 4,919). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
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 ratings and cooling
RTX 5070 is the lower-power option at 250 W TDP, compared with 350 W for RTX 3080 Ti. If render speed is close, that can make RTX 5070 easier to cool and run quietly.
Is the upgrade worthwhile?
RTX 5070 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.
Comparison summary
RTX 5070 leads the Blender benchmark score by 17.8%.
Fastest in Cycles: RTX 5070 18% faster than RTX 3080 Ti.
Most VRAM: Tie Same memory capacity.
Lowest power draw: RTX 5070 29% lower rating than RTX 3080 Ti.
Cheapest: RTX 5070 16% cheaper than RTX 3080 Ti.
Best value for money: RTX 5070 40% better value than RTX 3080 Ti.
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.
