Which GPU should you choose for Blender?
RTX 5090 D v2 is the stronger Blender rendering pick here, and both cards have the same VRAM capacity.
Cycles rendering performance
RTX 5090 D v2 leads by 28.5% in the Renderjuice Blender benchmark model (14,898 vs 11,592). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
Both cards have 24 GB of VRAM, so the decision is less about scene capacity and more about render speed, architecture, power draw, and price.
Power ratings and cooling
RTX 4090 is the lower-power option at 450 W TDP, compared with 575 W for RTX 5090 D v2. If render speed is close, that can make RTX 4090 easier to cool and run quietly.
Is the upgrade worthwhile?
RTX 5090 D v2 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 D v2 leads the Blender benchmark score by 28.5%.
Fastest in Cycles: RTX 5090 D v2 29% faster than RTX 4090.
Most VRAM: Tie Same memory capacity.
Lowest power draw: RTX 4090 22% lower rating than RTX 5090 D v2.
Cheapest: Cannot compare Price unavailable for some GPUs.
Best value for money: Cannot compare Price or benchmark unavailable for some GPUs.
Both GPUs ship with 24 GB of VRAM, so the tradeoff is more about speed, architecture, and efficiency than memory capacity.
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.
