Sony A6400 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 NX200 has a
20.0MP APS-C (23.5 x 15.7 mm ) sized CMOS sensor .
Below you can see the A6400 and NX200 sensor size comparison.
Sensor Size and Resolution Comparison image of Sony A6400 and Samsung NX200 Cameras
Sony A6400 and Samsung NX200 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

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 A6400
or the
Samsung NX200 ,
including hyperfocal distance.
