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 19.1% in the Renderjuice Blender benchmark model (7,848 vs 6,587). 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 PRO 4000 Blackwell 24 GB. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power ratings and cooling
RTX PRO 4000 Blackwell 24 GB is the lower-power option at 140 W TDP, compared with 300 W for L40S 48 GB. If render speed is close, that can make RTX PRO 4000 Blackwell 24 GB easier to cool and run quietly.
Is the upgrade worthwhile?
RTX PRO 4000 Blackwell 24 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 19.1%.
