Which GPU should you choose for Blender?
AI PRO R9700 32 GB is the stronger Blender rendering pick here based on benchmark score.
Cycles rendering performance
AI PRO R9700 32 GB leads by 184.0% in the Renderjuice Blender benchmark model (3,325 vs 1,171). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
AI PRO R9700 32 GB has more scene headroom with 32 GB of VRAM versus 8 GB on CMP 40HX 8 GB. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power ratings and cooling
CMP 40HX 8 GB is the lower-power option at 185 W TDP, compared with 300 W for AI PRO R9700 32 GB. If render speed is close, that can make CMP 40HX 8 GB easier to cool and run quietly.
Is the upgrade worthwhile?
AI PRO R9700 32 GB is both the newer and faster Blender rendering choice here. The main reason to choose CMP 40HX 8 GB would be price, availability, existing ownership, or a specific workstation requirement.
Comparison summary
AI PRO R9700 32 GB leads the Blender benchmark score by 184.0%.
Fastest in Cycles: AI PRO R9700 32 GB 184% faster than CMP 40HX 8 GB.
