Both Canon 1D X II and Canon 1D X II have Full frame sized 20.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Below you can see the 1D X MII and 1D X MII sensor size comparison.
Sensor Size and Resolution Comparison image of Canon 1D X II and Canon 1D X II Cameras
Canon 1D X II and Canon 1D X II 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.

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