Which GPU should you choose for Blender?
RX 6600 XT 8 GB is the stronger Blender rendering pick here, and both cards have the same VRAM capacity.
Cycles rendering performance
RX 6600 XT 8 GB leads by 4.7% in the Renderjuice Blender benchmark model (958 vs 915). 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 6700S 8 GB is the lower-power option at 80 W TDP, compared with 160 W for RX 6600 XT 8 GB. If render speed is close, that can make RX 6700S 8 GB easier to cool and run quietly.
Is the upgrade worthwhile?
RX 6700S 8 GB is newer, but RX 6600 XT 8 GB still leads this Blender benchmark comparison. That makes the older card worth considering when used pricing or VRAM capacity is favorable.
Comparison summary
RX 6600 XT 8 GB leads the Blender benchmark score by 4.7%.
Fastest in Cycles: RX 6600 XT 8 GB 5% faster than RX 6700S 8 GB.
Most VRAM: Tie Same memory capacity.
Lowest power draw: RX 6700S 8 GB 50% 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.
