Which GPU should you choose for Blender?
RTX PRO 4500 Blackwell 32 GB is faster for Blender rendering, but L40S 48 GB has more VRAM. That makes this a speed-versus-scene-headroom decision.
Cycles rendering performance
RTX PRO 4500 Blackwell 32 GB leads by 17.0% in the Renderjuice Blender benchmark model (9,186 vs 7,848). 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 32 GB on RTX PRO 4500 Blackwell 32 GB. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power ratings and cooling
RTX PRO 4500 Blackwell 32 GB is the lower-power option at 200 W TDP, compared with 300 W for L40S 48 GB. If render speed is close, that can make RTX PRO 4500 Blackwell 32 GB easier to cool and run quietly.
Is the upgrade worthwhile?
RTX PRO 4500 Blackwell 32 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.
