Which GPU should you choose for Blender?
RX 6800 16 GB is the stronger Blender rendering pick here based on benchmark score.
Cycles rendering performance
RX 6800 16 GB leads by 9.3% in the Renderjuice Blender benchmark model (2,116 vs 1,936). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
RX 6800 16 GB has more scene headroom with 16 GB of VRAM versus 12 GB on RX 7800M 12 GB. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power ratings and cooling
RX 7800M 12 GB is the lower-power option at 180 W TDP, compared with 250 W for RX 6800 16 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 newer, but RX 6800 16 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 6800 16 GB leads the Blender benchmark score by 9.3%.
Fastest in Cycles: RX 6800 16 GB 9% faster than RX 7800M 12 GB.
Most VRAM: RX 6800 16 GB 33% more VRAM than RX 7800M 12 GB.
Lowest power draw: RX 7800M 12 GB 28% lower rating than RX 6800 16 GB.
Cheapest: Cannot compare Price unavailable for some GPUs.
Best value for money: Cannot compare Price or benchmark unavailable for some GPUs.
RX 6800 16 GB has 16 GB of VRAM, while RX 7800M 12 GB has 12 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.
