Which GPU should you choose for Blender?
L40S 48 GB is the stronger Blender rendering pick here based on benchmark score.
Cycles rendering performance
L40S 48 GB leads by 48.9% in the Renderjuice Blender benchmark model (7,848 vs 5,271). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
L40S 48 GB has more scene headroom with 48 GB of VRAM versus 24 GB on RTX 3090 Ti. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power ratings and cooling
L40S 48 GB is the lower-power option at 300 W TDP, compared with 450 W for RTX 3090 Ti. If render speed is close, that can make L40S 48 GB easier to cool and run quietly.
Is the upgrade worthwhile?
L40S 48 GB is the straightforward performance pick, while RTX 3090 Ti needs a price, power, availability, or compatibility advantage to make more sense.
Comparison summary
L40S 48 GB leads the Blender benchmark score by 48.9%.
Fastest in Cycles: L40S 48 GB 49% faster than RTX 3090 Ti.
Most VRAM: L40S 48 GB 100% more VRAM than RTX 3090 Ti.
Lowest power draw: L40S 48 GB 33% lower rating than RTX 3090 Ti.
Cheapest: Cannot compare Price unavailable for some GPUs.
Best value for money: Cannot compare Price or benchmark unavailable for some GPUs.
L40S 48 GB has 48 GB of VRAM, while RTX 3090 Ti has 24 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.
