Which GPU should you choose for Blender?
RTX 4070 is the stronger Blender rendering pick here based on benchmark score.
Cycles rendering performance
RTX 4070 leads by 73.0% in the Renderjuice Blender benchmark model (5,141 vs 2,972). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
RTX 4070 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 4070 is the lower-power option at 200 W TDP, compared with 220 W for RTX 3070. If render speed is close, that can make RTX 4070 easier to cool and run quietly.
Is the upgrade worthwhile?
RTX 4070 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 4070 leads the Blender benchmark score by 73.0%.
Fastest in Cycles: RTX 4070 73% faster than RTX 3070.
Most VRAM: RTX 4070 50% more VRAM than RTX 3070.
Lowest power draw: RTX 4070 9% lower rating than RTX 3070.
Cheapest: RTX 3070 44% cheaper than RTX 4070.
Best value for money: RTX 3070 3% better value than RTX 4070.
RTX 3070 has 8 GB of VRAM, while RTX 4070 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.
