Which GPU should you choose for Blender?
RTX PRO 5000 Blackwell 48 GB is the stronger Blender rendering pick here, and both cards have the same VRAM capacity.
Cycles rendering performance
RTX PRO 5000 Blackwell 48 GB leads by 39.3% in the Renderjuice Blender benchmark model (10,929 vs 7,848). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
Both cards have 48 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
Both cards list a 300 W TDP, so power draw is not the deciding spec on paper. Cooling, case airflow, and actual board partner limits still matter.
Is the upgrade worthwhile?
RTX PRO 5000 Blackwell 48 GB is both the newer and faster Blender rendering choice here. The main reason to choose L40S 48 GB would be price, availability, existing ownership, or a specific workstation requirement.
Comparison summary
RTX PRO 5000 Blackwell 48 GB leads the Blender benchmark score by 39.3%.
Fastest in Cycles: RTX PRO 5000 Blackwell 48 GB 39% faster than L40S 48 GB.
Most VRAM: Tie Same memory capacity.
Lowest power draw: Tie Same power rating.
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 48 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.
