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 50.5% in the Renderjuice Blender benchmark model (11,592 vs 7,705). 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 5070 Ti. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power ratings and cooling
RTX 5070 Ti is the lower-power option at 300 W TDP, compared with 450 W for RTX 4090. If render speed is close, that can make RTX 5070 Ti easier to cool and run quietly.
Is the upgrade worthwhile?
RTX 5070 Ti 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 50.5%.
Fastest in Cycles: RTX 4090 50% faster than RTX 5070 Ti.
Most VRAM: RTX 4090 50% more VRAM than RTX 5070 Ti.
Lowest power draw: RTX 5070 Ti 33% lower rating than RTX 4090.
Cheapest: RTX 5070 Ti 72% cheaper than RTX 4090.
Best value for money: RTX 5070 Ti 135% better value than RTX 4090.
RTX 4090 has 24 GB of VRAM, while RTX 5070 Ti 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.
