Nikon D800E has a
36.0MP Full frame (35.9 x 24 mm ) sized CMOS sensor and features Expeed 3 processor. On the other hand, Sony A7 IV has a
33.0MP Full frame (35.8 x 23.8 mm ) sized BSI-CMOS sensor and features Bionz XR processor.
Another similarity between these two cameras is that both Sony A7 IV 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 A7 IV sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon D800E and Sony A7 IV Cameras
Nikon D800E and Sony A7 IV have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the same focal length and aperture.
DxOMark Sensor Scores
DxOMark is a benchmark that scientifically assesses image quality of camera sensors. It scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score. Nikon D800E and Sony A7 IV sensors have been tested by DxO and the results show that A7 IV has a better overall score of 97, 1 points higher compared to D800E's score of 96.

Sensor size sets the circle of confusion, so it drives how much depth of field each
of these bodies gives you at a given aperture. You can calculate it exactly for the
Nikon D800E
or the
Sony A7 IV ,
including hyperfocal distance.
