Nikon D3X has a
25.0MP Full frame (35.9 x 24 mm ) sized CMOS sensor and features Expeed 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 D3X and D5 sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon D3X and Nikon D5 Cameras
Nikon D3X 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.

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 D3X
or the
Nikon D5 ,
including hyperfocal distance.
