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 77.7% in the Renderjuice Blender benchmark model (9,134 vs 5,141). 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 12 GB on RTX 4070. 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 360 W for RTX 5080. If render speed is close, that can make RTX 4070 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 4070 would be price, availability, existing ownership, or a specific workstation requirement.
Comparison summary
RTX 5080 leads the Blender benchmark score by 77.7%.
Fastest in Cycles: RTX 5080 78% faster than RTX 4070.
Most VRAM: RTX 5080 33% more VRAM than RTX 4070.
Lowest power draw: RTX 4070 44% lower rating than RTX 5080.
Cheapest: RTX 4070 56% cheaper than RTX 5080.
Best value for money: RTX 4070 28% better value than RTX 5080.
RTX 4070 has 12 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.
