Both Samsung NX30 and Nikon S3600 have 20.0 MP resolution sensors but Samsung NX30's sensor is APS-C (23.5 x 15.7 mm ) and Nikon S3600's sensor is 1/2.3-inch (6.17 x 4.55 mm ).
Since Samsung NX30's has a larger sensor area with the same resolution, this means that it also has a larger pixel area hence better light collecting capacity for a given aperture compared to Nikon S3600.
Below you can see the NX30 and S3600 sensor size comparison.

As seen above, Samsung NX30 has a 13.1x Larger sensor area than Nikon S3600. 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.
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 NX30
or the
Nikon S3600 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(APS-C versus 1/2.3-inch),
so compare them at the same framing rather than the same focal length.
Put the same focal length on the smaller sensor and it will show less depth of
field, not more, because it also crops tighter. The calculator shows the
full frame equivalent focal length for each body so you can match the framing.
