Which GPU should you choose for Blender?
RTX 5080 is the stronger Blender rendering pick here, and both cards have the same VRAM capacity.
Cycles rendering performance
RTX 5080 leads by 10.3% in the Renderjuice Blender benchmark model (9,134 vs 8,285). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
Both cards have 16 GB of VRAM, so the decision is less about scene capacity and more about render speed, architecture, power draw, and price.
Power ratings and cooling
RTX 4080 is the lower-power option at 320 W TDP, compared with 360 W for RTX 5080. If render speed is close, that can make RTX 4080 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 4080 would be price, availability, existing ownership, or a specific workstation requirement.
Comparison summary
RTX 5080 leads the Blender benchmark score by 10.3%.
Fastest in Cycles: RTX 5080 10% faster than RTX 4080.
Most VRAM: Tie Same memory capacity.
Lowest power draw: RTX 4080 11% lower rating than RTX 5080.
Cheapest: RTX 4080 26% cheaper than RTX 5080.
Best value for money: RTX 4080 23% better value than RTX 5080.
Both GPUs ship with 16 GB of VRAM, so the tradeoff is more about speed, architecture, and efficiency than memory capacity.
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.
