Sony A6600 has a
24.0MP APS-C (23.5 x 15.6 mm ) sized CMOS sensor and features Bionz X processor. On the other hand, Samsung NX20 has a
20.0MP APS-C (23.5 x 15.7 mm ) sized CMOS sensor .
Below you can see the A6600 and NX20 sensor size comparison.
Sensor Size and Resolution Comparison image of Sony A6600 and Samsung NX20 Cameras
Sony A6600 and Samsung NX20 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
Both Sony A6600 and Samsung NX20 sensors have been tested by DxoMark. DxoMark 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. Of the two cameras that we are comparing, A6600 has scored 82, 7 points higher than NX20.

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
Sony A6600
or the
Samsung NX20 ,
including hyperfocal distance.
