Which GPU should you choose for Blender?
RTX PRO 4000 Blackwell 24 GB is the stronger Blender rendering pick here, and both cards have the same VRAM capacity.
Cycles rendering performance
RTX PRO 4000 Blackwell 24 GB leads by 91.1% in the Renderjuice Blender benchmark model (6,587 vs 3,447). 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
L4 24 GB is the lower-power option at 72 W TDP, compared with 140 W for RTX PRO 4000 Blackwell 24 GB. If render speed is close, that can make L4 24 GB easier to cool and run quietly.
Is the upgrade worthwhile?
RTX PRO 4000 Blackwell 24 GB is both the newer and faster Blender rendering choice here. The main reason to choose L4 24 GB would be price, availability, existing ownership, or a specific workstation requirement.
Comparison summary
RTX PRO 4000 Blackwell 24 GB leads the Blender benchmark score by 91.1%.
Fastest in Cycles: RTX PRO 4000 Blackwell 24 GB 91% faster than L4 24 GB.
Most VRAM: Tie Same memory capacity.
Lowest power draw: L4 24 GB 49% lower rating than RTX PRO 4000 Blackwell 24 GB.
Cheapest: RTX PRO 4000 Blackwell 24 GB 22% cheaper than L4 24 GB.
Best value for money: RTX PRO 4000 Blackwell 24 GB 146% better value than L4 24 GB.
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.
