Samsung NX20 has a
20.0MP APS-C (23.5 x 15.7 mm ) sized CMOS sensor . On the other hand, Canon M6 has a
24.0MP APS-C (22.3 x 14.9 mm ) sized CMOS sensor and features Digic 7 processor.
Below you can see the NX20 and M6 sensor size comparison.
Sensor Size and Resolution Comparison image of Samsung NX20 and Canon M6 Cameras
As seen above, Samsung NX20 has a 1.1x Larger sensor area than Canon M6. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in 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 NX20 and Canon M6 sensors have been tested by DxO and the results show that M6 has a better overall score of 78, 3 points higher compared to NX20's score of 75.

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 NX20
or the
Canon M6 ,
including hyperfocal distance.
