Which GPU should you choose for Blender?
CMP 40HX 8 GB is faster for Blender rendering, but A2 16 GB has more VRAM. That makes this a speed-versus-scene-headroom decision.
Cycles rendering performance
CMP 40HX 8 GB leads by 19.1% in the Renderjuice Blender benchmark model (1,171 vs 983). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
A2 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
A2 16 GB is the lower-power option at 60 W TDP, compared with 185 W for CMP 40HX 8 GB. If render speed is close, that can make A2 16 GB easier to cool and run quietly.
Is the upgrade worthwhile?
CMP 40HX 8 GB is the straightforward performance pick, while A2 16 GB needs a price, power, availability, or compatibility advantage to make more sense.
Comparison summary
CMP 40HX 8 GB leads the Blender benchmark score by 19.1%.
Fastest in Cycles: CMP 40HX 8 GB 19% faster than A2 16 GB.
Most VRAM: A2 16 GB 100% more VRAM than CMP 40HX 8 GB.
Lowest power draw: A2 16 GB 68% lower rating than CMP 40HX 8 GB.
Cheapest: Cannot compare Price unavailable for some GPUs.
