Which GPU should you choose for Blender?
RX 6700S 8 GB is faster for Blender rendering, but RX 6700M 10 GB has more VRAM. That makes this a speed-versus-scene-headroom decision.
Cycles rendering performance
RX 6700S 8 GB leads by 13.4% in the Renderjuice Blender benchmark model (915 vs 807). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
RX 6700M 10 GB has more scene headroom with 10 GB of VRAM versus 8 GB on RX 6700S 8 GB. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power ratings and cooling
RX 6700S 8 GB is the lower-power option at 80 W TDP, compared with 135 W for RX 6700M 10 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 both the newer and faster Blender rendering choice here. The main reason to choose RX 6700M 10 GB would be price, availability, existing ownership, or a specific workstation requirement.
Comparison summary
RX 6700S 8 GB leads the Blender benchmark score by 13.4%.
Fastest in Cycles: RX 6700S 8 GB 13% faster than RX 6700M 10 GB.
Most VRAM: RX 6700M 10 GB 25% more VRAM than RX 6700S 8 GB.
Lowest power draw: RX 6700S 8 GB 41% lower rating than RX 6700M 10 GB.
Cheapest: Cannot compare Price unavailable for some GPUs.
Best value for money: Cannot compare Price or benchmark unavailable for some GPUs.
RX 6700M 10 GB has 10 GB of VRAM, while RX 6700S 8 GB has 8 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.
