Which GPU should you choose for Blender?
RTX 5090 is the stronger Blender rendering pick here based on benchmark score.
Cycles rendering performance
RTX 5090 leads by 93.9% in the Renderjuice Blender benchmark model (16,066 vs 8,284). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
RTX 5090 has more scene headroom with 32 GB of VRAM versus 16 GB on RTX 4080. 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 575 W for RTX 5090. If render speed is close, that can make RTX 4080 easier to cool and run quietly.
Is the upgrade worthwhile?
RTX 5090 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 5090 leads the Blender benchmark score by 93.9%.
Fastest in Cycles: RTX 5090 94% faster than RTX 4080.
Most VRAM: RTX 5090 100% more VRAM than RTX 4080.
Lowest power draw: RTX 4080 44% lower rating than RTX 5090.
Cheapest: RTX 4080 79% cheaper than RTX 5090.
Best value for money: RTX 4080 145% better value than RTX 5090.
RTX 4080 has 16 GB of VRAM, while RTX 5090 has 32 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.
