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 71.0% in the Renderjuice Blender benchmark model (8,284 vs 4,843). 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 3080 Ti. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power ratings and cooling
RTX 4080 is the lower-power option at 320 W TDP, compared with 350 W for RTX 3080 Ti. If render speed is close, that can make RTX 4080 easier to cool and run quietly.
Is the upgrade worthwhile?
RTX 4080 is both the newer and faster Blender rendering choice here. The main reason to choose RTX 3080 Ti would be price, availability, existing ownership, or a specific workstation requirement.
Comparison summary
RTX 4080 leads the Blender benchmark score by 71.0%.
Fastest in Cycles: RTX 4080 71% faster than RTX 3080 Ti.
Most VRAM: RTX 4080 33% more VRAM than RTX 3080 Ti.
Lowest power draw: RTX 4080 9% lower rating than RTX 3080 Ti.
Cheapest: RTX 3080 Ti 33% cheaper than RTX 4080.
Best value for money: RTX 4080 14% better value than RTX 3080 Ti.
RTX 3080 Ti has 12 GB of VRAM, while RTX 4080 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.
