Which GPU should you choose for Blender?
CMP 40HX 8 GB is faster for Blender rendering, but RX 6700M 10 GB has more VRAM. That makes this a speed-versus-scene-headroom decision.
Cycles rendering performance
CMP 40HX 8 GB leads by 45.1% in the Renderjuice Blender benchmark model (1,171 vs 807). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
RX 6700M 10 GB has more scene headroom with 10 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
RX 6700M 10 GB is the lower-power option at 135 W TDP, compared with 185 W for CMP 40HX 8 GB. If render speed is close, that can make RX 6700M 10 GB easier to cool and run quietly.
Is the upgrade worthwhile?
CMP 40HX 8 GB is the straightforward performance pick, while RX 6700M 10 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 45.1%.
Fastest in Cycles: CMP 40HX 8 GB 45% faster than RX 6700M 10 GB.
Most VRAM: RX 6700M 10 GB 25% more VRAM than CMP 40HX 8 GB.
Lowest power draw: RX 6700M 10 GB 27% lower rating than CMP 40HX 8 GB.
