Which GPU should you choose for Blender?
RX 7800M 12 GB is the stronger Blender rendering pick here, and both cards have the same VRAM capacity.
Cycles rendering performance
RX 7800M 12 GB leads by 19.8% in the Renderjuice Blender benchmark model (1,936 vs 1,615). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
Both cards have 12 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 7800M 12 GB is the lower-power option at 180 W TDP, compared with 230 W for RX 6700 XT 12 GB. If render speed is close, that can make RX 7800M 12 GB easier to cool and run quietly.
Is the upgrade worthwhile?
RX 7800M 12 GB is both the newer and faster Blender rendering choice here. The main reason to choose RX 6700 XT 12 GB would be price, availability, existing ownership, or a specific workstation requirement.
Comparison summary
RX 7800M 12 GB leads the Blender benchmark score by 19.8%.
Fastest in Cycles: RX 7800M 12 GB 20% faster than RX 6700 XT 12 GB.
Most VRAM: Tie Same memory capacity.
Lowest power draw: RX 7800M 12 GB 22% lower rating than RX 6700 XT 12 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 12 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.
