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 100.1% in the Renderjuice Blender benchmark model (11,592 vs 5,792). 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 12 GB on RTX 5070. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power ratings and cooling
RTX 5070 is the lower-power option at 250 W TDP, compared with 450 W for RTX 4090. If render speed is close, that can make RTX 5070 easier to cool and run quietly.
Is the upgrade worthwhile?
RTX 5070 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 100.1%.
Fastest in Cycles: RTX 4090 100% faster than RTX 5070.
Most VRAM: RTX 4090 100% more VRAM than RTX 5070.
Lowest power draw: RTX 5070 44% lower rating than RTX 4090.
Cheapest: RTX 5070 80% cheaper than RTX 4090.
Best value for money: RTX 5070 153% better value than RTX 4090.
RTX 4090 has 24 GB of VRAM, while RTX 5070 has 12 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.
