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 12.7% in the Renderjuice Blender benchmark model (5,792 vs 5,141). 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 4070 is the lower-power option at 200 W TDP, compared with 250 W for RTX 5070. If render speed is close, that can make RTX 4070 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 4070 would be price, availability, existing ownership, or a specific workstation requirement.
Comparison summary
RTX 5070 leads the Blender benchmark score by 12.7%.
Fastest in Cycles: RTX 5070 13% faster than RTX 4070.
Most VRAM: Tie Same memory capacity.
Lowest power draw: RTX 4070 20% lower rating than RTX 5070.
Cheapest: RTX 4070 1% cheaper than RTX 5070.
Best value for money: RTX 5070 11% better value than RTX 4070.
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.
