Which GPU should you choose for Blender?
RTX PRO 4000 Blackwell 24 GB is the stronger Blender rendering pick here based on benchmark score.
Cycles rendering performance
RTX PRO 4000 Blackwell 24 GB leads by 570.2% in the Renderjuice Blender benchmark model (6,587 vs 983). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
RTX PRO 4000 Blackwell 24 GB has more scene headroom with 24 GB of VRAM versus 16 GB on A2 16 GB. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power ratings and cooling
A2 16 GB is the lower-power option at 60 W TDP, compared with 140 W for RTX PRO 4000 Blackwell 24 GB. If render speed is close, that can make A2 16 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 A2 16 GB would be price, availability, existing ownership, or a specific workstation requirement.
