Nikon D4 has a
16.0MP Full frame (36 x 23.9 mm ) sized CMOS sensor and features Expeed 3 processor. On the other hand, Canon 1D X has a
18.0MP Full frame (36 x 24 mm ) sized CMOS sensor and features Dual Digic 5+ processor.
Below you can see the D4 and 1D X sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon D4 and Canon 1D X Cameras
Nikon D4 and Canon 1D X 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
Both Nikon D4 and Canon 1D X sensors have been tested by DxoMark. DxoMark 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. Of the two cameras that we are comparing, D4 has scored 89, 7 points higher than 1D X.

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 D4
or the
Canon 1D X ,
including hyperfocal distance.
