Which GPU should you choose for Blender?
RTX 5080 is the stronger Blender rendering pick here based on benchmark score.
Cycles rendering performance
RTX 5080 leads by 208.8% in the Renderjuice Blender benchmark model (9,128 vs 2,956). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
RTX 5080 has more scene headroom with 16 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 360 W for RTX 5080. If render speed is close, that can make RTX 3070 easier to cool and run quietly.
Is the upgrade worthwhile?
RTX 5080 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 5080 leads the Blender benchmark score by 208.8%.
Fastest in Cycles: RTX 5080 209% faster than RTX 3070.
Most VRAM: RTX 5080 100% more VRAM than RTX 3070.
Lowest power draw: RTX 3070 39% lower rating than RTX 5080.
Cheapest: RTX 3070 72% cheaper than RTX 5080.
Best value for money: RTX 3070 17% better value than RTX 5080.
RTX 3070 has 8 GB of VRAM, while RTX 5080 has 16 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.
