Both Samsung NX11 and Samsung NX10 have APS-C sized 15.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Below you can see the NX11 and NX10 sensor size comparison.

Samsung NX11 and Samsung NX10 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
Samsung NX11
or the
Samsung NX10 ,
including hyperfocal distance.
