Which GPU should you choose for Blender?
RTX 5080 is faster for Blender rendering, but RTX 3090 Ti has more VRAM. That makes this a speed-versus-scene-headroom decision.
Cycles rendering performance
RTX 5080 leads by 73.6% in the Renderjuice Blender benchmark model (9,134 vs 5,261). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
RTX 3090 Ti has more scene headroom with 24 GB of VRAM versus 16 GB on RTX 5080. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power ratings and cooling
RTX 5080 is the lower-power option at 360 W TDP, compared with 450 W for RTX 3090 Ti. If render speed is close, that can make RTX 5080 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 3090 Ti would be price, availability, existing ownership, or a specific workstation requirement.
Comparison summary
RTX 5080 leads the Blender benchmark score by 73.6%.
Fastest in Cycles: RTX 5080 74% faster than RTX 3090 Ti.
Most VRAM: RTX 3090 Ti 50% more VRAM than RTX 5080.
Lowest power draw: RTX 5080 20% lower rating than RTX 3090 Ti.
Cheapest: RTX 5080 27% cheaper than RTX 3090 Ti.
Best value for money: RTX 5080 138% better value than RTX 3090 Ti.
RTX 3090 Ti has 24 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.
