Which GPU should you choose for Blender?
RX 6600M 8 GB is the stronger Blender rendering pick here, and both cards have the same VRAM capacity.
Cycles rendering performance
RX 6600M 8 GB leads by 11.0% in the Renderjuice Blender benchmark model (837 vs 754). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
Both cards have 8 GB of VRAM, so the decision is less about scene capacity and more about render speed, architecture, power draw, and price.
Power ratings and cooling
RX 6600M 8 GB is the lower-power option at 100 W TDP, compared with 132 W for RX 6600 8 GB. If render speed is close, that can make RX 6600M 8 GB easier to cool and run quietly.
Is the upgrade worthwhile?
RX 6600M 8 GB is the straightforward performance pick, while RX 6600 8 GB needs a price, power, availability, or compatibility advantage to make more sense.
Comparison summary
RX 6600M 8 GB leads the Blender benchmark score by 11.0%.
Fastest in Cycles: RX 6600M 8 GB 11% faster than RX 6600 8 GB.
Most VRAM: Tie Same memory capacity.
Lowest power draw: RX 6600M 8 GB 24% lower rating than RX 6600 8 GB.
