Which GPU should you choose for Blender?
RTX PRO 4000 Blackwell 24 GB is faster for Blender rendering, but PRO W6800 32 GB has more VRAM. That makes this a speed-versus-scene-headroom decision.
Cycles rendering performance
RTX PRO 4000 Blackwell 24 GB leads by 238.5% in the Renderjuice Blender benchmark model (6,587 vs 1,946). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
PRO W6800 32 GB has more scene headroom with 32 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 250 W for PRO W6800 32 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 both the newer and faster Blender rendering choice here. The main reason to choose PRO W6800 32 GB would be price, availability, existing ownership, or a specific workstation requirement.
