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 39.1% in the Renderjuice Blender benchmark model (16,123 vs 11,592). 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 24 GB on RTX 4090. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power ratings and cooling
RTX 4090 is the lower-power option at 450 W TDP, compared with 575 W for RTX 5090. If render speed is close, that can make RTX 4090 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 4090 would be price, availability, existing ownership, or a specific workstation requirement.
Comparison summary
RTX 5090 leads the Blender benchmark score by 39.1%.
Fastest in Cycles: RTX 5090 39% faster than RTX 4090.
Most VRAM: RTX 5090 33% more VRAM than RTX 4090.
Lowest power draw: RTX 4090 22% lower rating than RTX 5090.
Cheapest: RTX 4090 42% cheaper than RTX 5090.
Best value for money: RTX 4090 23% better value than RTX 5090.
RTX 4090 has 24 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.
