Which GPU should you choose for Blender?
CMP 40HX 8 GB is faster for Blender rendering, but Pro VII 16 GB has more VRAM. That makes this a speed-versus-scene-headroom decision.
Cycles rendering performance
CMP 40HX 8 GB leads by 9.0% in the Renderjuice Blender benchmark model (1,171 vs 1,074). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
Pro VII 16 GB has more scene headroom with 16 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 250 W for Pro VII 16 GB. If render speed is close, that can make CMP 40HX 8 GB easier to cool and run quietly.
Is the upgrade worthwhile?
CMP 40HX 8 GB is both the newer and faster Blender rendering choice here. The main reason to choose Pro VII 16 GB would be price, availability, existing ownership, or a specific workstation requirement.
Comparison summary
CMP 40HX 8 GB leads the Blender benchmark score by 9.0%.
Fastest in Cycles: CMP 40HX 8 GB 9% faster than Pro VII 16 GB.
Most VRAM: Pro VII 16 GB 100% more VRAM than CMP 40HX 8 GB.
Lowest power draw: CMP 40HX 8 GB 26% lower rating than Pro VII 16 GB.
Cheapest: Cannot compare Price unavailable for some GPUs.
Best value for money: Cannot compare Price or benchmark unavailable for some GPUs.
CMP 40HX 8 GB has 8 GB of VRAM, while Pro VII 16 GB has 16 GB, which matters when scenes, textures, or geometry get heavier.
If you are deciding between these cards for Blender, focus first on Blender benchmark score, VRAM capacity, memory bandwidth, and whether your scenes are likely to benefit more from raw speed or extra memory headroom. The comparison table above keeps those tradeoffs in one place.
