Samsung NX10 has a
15.0MP APS-C (23.4 x 15.6 mm ) sized CMOS sensor and features DRIM Engine processor. On the other hand, Canon 7D MII has a
20.0MP APS-C (22.4 x 15 mm ) sized CMOS sensor and features DIGIC 6 (dual) processor.
Canon 7D MII's sensor provides 5MP more than Samsung NX10's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Below you can see the NX10 and 7D MII sensor size comparison.
Sensor Size and Resolution Comparison image of Samsung NX10 and Canon 7D MII Cameras
Samsung NX10 and Canon 7D MII 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. Samsung NX10 and Canon 7D MII sensors have been tested by DxO and the results show that 7D MII has a better overall score of 70, 7 points higher compared to NX10's score of 63.

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 NX10
or the
Canon 7D MII ,
including hyperfocal distance.
