Which GPU should you choose for Blender?
RX 7650 GRE 8 GB is the stronger Blender rendering pick here, and both cards have the same VRAM capacity.
Cycles rendering performance
RX 7650 GRE 8 GB leads by 4.7% in the Renderjuice Blender benchmark model (1,226 vs 1,171). 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 7650 GRE 8 GB is the lower-power option at 165 W TDP, compared with 185 W for CMP 40HX 8 GB. If render speed is close, that can make RX 7650 GRE 8 GB easier to cool and run quietly.
Is the upgrade worthwhile?
RX 7650 GRE 8 GB is both the newer and faster Blender rendering choice here. The main reason to choose CMP 40HX 8 GB would be price, availability, existing ownership, or a specific workstation requirement.
Comparison summary
RX 7650 GRE 8 GB leads the Blender benchmark score by 4.7%.
Fastest in Cycles: RX 7650 GRE 8 GB 5% faster than CMP 40HX 8 GB.
Most VRAM: Tie Same memory capacity.
Lowest power draw: RX 7650 GRE 8 GB 11% 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.
Both GPUs ship with 8 GB of VRAM, so the tradeoff is more about speed, architecture, and efficiency than memory capacity.
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.
