Both Nikon D800E and Sony A7R have Full frame sized 36.0 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 and Nikon D800E 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 D800E and A7R sensor size comparison.
Nikon D800E and Sony A7R 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.
