Which GPU should you choose for Blender?
RTX 5070 is the stronger Blender rendering pick here based on benchmark score.
Cycles rendering performance
RTX 5070 leads by 38.0% in the Renderjuice Blender benchmark model (5,792 vs 4,197). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
RTX 5070 has more scene headroom with 12 GB of VRAM versus 10 GB on RTX 3080 10 GB. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power ratings and cooling
RTX 5070 is the lower-power option at 250 W TDP, compared with 320 W for RTX 3080 10 GB. 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 10 GB would be price, availability, existing ownership, or a specific workstation requirement.
Comparison summary
RTX 5070 leads the Blender benchmark score by 38.0%.
Fastest in Cycles: RTX 5070 38% faster than RTX 3080 10 GB.
Most VRAM: RTX 5070 20% more VRAM than RTX 3080 10 GB.
Lowest power draw: RTX 5070 22% lower rating than RTX 3080 10 GB.
Cheapest: RTX 3080 10 GB 23% cheaper than RTX 5070.
Best value for money: RTX 5070 6% better value than RTX 3080 10 GB.
RTX 3080 10 GB has 10 GB of VRAM, while RTX 5070 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.
