Both Sony A7R III and Sony A7R III have Full frame sized 42.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Another similarity between these two cameras is that both Sony A7R III and Sony A7R III sensors lack anti-alias (Low-Pass) filters. Removing anti-alias filter increases the sharpness and level of detail but at the same time, it increases the chance of moiré occurring in certain scenes.
Below you can see the A7R III and A7R III sensor size comparison.
Sony A7R III and Sony A7R III have the same sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture.
