Which GPU should you choose for Blender?
L40S 48 GB is the stronger Blender rendering pick here, and both cards have the same VRAM capacity.
Cycles rendering performance
L40S 48 GB leads by 116.9% in the Renderjuice Blender benchmark model (7,848 vs 3,619). 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
PRO W7900 48 GB is the lower-power option at 295 W TDP, compared with 300 W for L40S 48 GB. If render speed is close, that can make PRO W7900 48 GB easier to cool and run quietly.
Is the upgrade worthwhile?
PRO W7900 48 GB is newer, but L40S 48 GB still leads this Blender benchmark comparison. That makes the older card worth considering when used pricing or VRAM capacity is favorable.
Comparison summary
L40S 48 GB leads the Blender benchmark score by 116.9%.
Fastest in Cycles: L40S 48 GB 117% faster than PRO W7900 48 GB.
Most VRAM: Tie Same memory capacity.
Lowest power draw: PRO W7900 48 GB 2% lower rating than L40S 48 GB.
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.
