Samsung NX300 has a
20.0MP APS-C (23.5 x 15.7 mm ) sized CMOS sensor and features DRIMe IV processor. On the other hand, Nikon D610 has a
24.0MP Full frame (35.9 x 24 mm ) sized CMOS sensor and features Expeed 3 processor.
Below you can see the NX300 and D610 sensor size comparison.
Sensor Size and Resolution Comparison image of Samsung NX300 and Nikon D610 Cameras
As seen above, Nikon D610 has a 2.3x Larger sensor area than Samsung NX300. 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 NX300 and Nikon D610 sensors have been tested by DxO and the results show that D610 has a better overall score of 94, 18 points higher compared to NX300's score of 76.

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 NX300
or the
Nikon D610 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(APS-C versus Full frame),
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.
