Which GPU should you choose for Blender?

RX 6700 10 GB is the stronger Blender rendering pick here based on benchmark score.

Cycles rendering performance

RX 6700 10 GB leads by 11.3% in the Renderjuice Blender benchmark model (1,303 vs 1,171). For render-time-first decisions, that is the card to prioritize.

VRAM and scene capacity

RX 6700 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 6700 10 GB is the lower-power option at 175 W TDP, compared with 185 W for CMP 40HX 8 GB. If render speed is close, that can make RX 6700 10 GB easier to cool and run quietly.

Is the upgrade worthwhile?

RX 6700 10 GB is the straightforward performance pick, while CMP 40HX 8 GB needs a price, power, availability, or compatibility advantage to make more sense.

Comparison summary

RX 6700 10 GB leads the Blender benchmark score by 11.3%.

Fastest in Cycles: RX 6700 10 GB 11% faster than CMP 40HX 8 GB.

Most VRAM: RX 6700 10 GB 25% more VRAM than CMP 40HX 8 GB.

Lowest power draw: RX 6700 10 GB 5% lower rating than CMP 40HX 8 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 RX 6700 10 GB has 10 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.
