Which GPU should you choose for Blender?
RTX 4090 is the stronger Blender rendering pick here based on benchmark score.
Cycles rendering performance
RTX 4090 leads by 43.4% in the Renderjuice Blender benchmark model (11,571 vs 8,067). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
RTX 4090 has more scene headroom with 24 GB of VRAM versus 16 GB on RTX 4080 SUPER. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power ratings and cooling
RTX 4080 SUPER is the lower-power option at 320 W TDP, compared with 450 W for RTX 4090. If render speed is close, that can make RTX 4080 SUPER easier to cool and run quietly.
Is the upgrade worthwhile?
RTX 4080 SUPER is newer, but RTX 4090 still leads this Blender benchmark comparison. That makes the older card worth considering when used pricing or VRAM capacity is favorable.
Comparison summary
RTX 4090 leads the Blender benchmark score by 43.4%.
Fastest in Cycles: RTX 4090 43% faster than RTX 4080 SUPER.
Most VRAM: RTX 4090 50% more VRAM than RTX 4080 SUPER.
Lowest power draw: RTX 4080 SUPER 29% lower rating than RTX 4090.
Cheapest: RTX 4080 SUPER 59% cheaper than RTX 4090.
Best value for money: RTX 4080 SUPER 69% better value than RTX 4090.
RTX 4080 SUPER has 16 GB of VRAM, while RTX 4090 has 24 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.
