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 117.6% in the Renderjuice Blender benchmark model (9,134 vs 4,197). 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 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 3080 10 GB 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 3080 10 GB 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 3080 10 GB would be price, availability, existing ownership, or a specific workstation requirement.
Comparison summary
RTX 5080 leads the Blender benchmark score by 117.6%.
Fastest in Cycles: RTX 5080 118% faster than RTX 3080 10 GB.
Most VRAM: RTX 5080 60% more VRAM than RTX 3080 10 GB.
Lowest power draw: RTX 3080 10 GB 11% lower rating than RTX 5080.
Cheapest: RTX 3080 10 GB 65% cheaper than RTX 5080.
Best value for money: RTX 3080 10 GB 30% better value than RTX 5080.
RTX 3080 10 GB has 10 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.
