Canon 5D MIII has a
22.0MP Full frame (36 x 24 mm ) sized CMOS sensor and features Digic 5+ processor. On the other hand, Nikon D5 has a
21.0MP Full frame (35.8 x 23.9 mm ) sized CMOS sensor and features Expeed 5 processor.
Below you can see the 5D MIII and D5 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon 5D MIII and Nikon D5 Cameras
Canon 5D MIII and Nikon D5 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. Canon 5D MIII and Nikon D5 sensors have been tested by DxO and the results show that D5 has a better overall score of 88, 7 points higher compared to 5D MIII's score of 81.

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
Canon 5D MIII
or the
Nikon D5 ,
including hyperfocal distance.
