Which GPU should you choose for Blender?
RTX 4080 is the stronger Blender rendering pick here based on benchmark score.
Cycles rendering performance
RTX 4080 leads by 43.0% in the Renderjuice Blender benchmark model (8,285 vs 5,792). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
RTX 4080 has more scene headroom with 16 GB of VRAM versus 12 GB on RTX 5070. 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 4080. If render speed is close, that can make RTX 5070 easier to cool and run quietly.
Is the upgrade worthwhile?
RTX 5070 is newer, but RTX 4080 still leads this Blender benchmark comparison. That makes the older card worth considering when used pricing or VRAM capacity is favorable.
Comparison summary
RTX 4080 leads the Blender benchmark score by 43.0%.
Fastest in Cycles: RTX 4080 43% faster than RTX 5070.
Most VRAM: RTX 4080 33% more VRAM than RTX 5070.
Lowest power draw: RTX 5070 22% lower rating than RTX 4080.
Cheapest: RTX 5070 37% cheaper than RTX 4080.
Best value for money: RTX 5070 12% better value than RTX 4080.
RTX 4080 has 16 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.
