Which GPU should you choose for Blender?
RX 6800S 8 GB is the stronger Blender rendering pick here, and both cards have the same VRAM capacity.
Cycles rendering performance
RX 6800S 8 GB leads by 5.0% in the Renderjuice Blender benchmark model (1,006 vs 958). 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 6800S 8 GB is the lower-power option at 100 W TDP, compared with 160 W for RX 6600 XT 8 GB. If render speed is close, that can make RX 6800S 8 GB easier to cool and run quietly.
Is the upgrade worthwhile?
RX 6800S 8 GB is both the newer and faster Blender rendering choice here. The main reason to choose RX 6600 XT 8 GB would be price, availability, existing ownership, or a specific workstation requirement.
Comparison summary
RX 6800S 8 GB leads the Blender benchmark score by 5.0%.
Fastest in Cycles: RX 6800S 8 GB 5% faster than RX 6600 XT 8 GB.
Most VRAM: Tie Same memory capacity.
Lowest power draw: RX 6800S 8 GB 38% lower rating than RX 6600 XT 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.
