Both Pentax MX-1 and Nikon P330 have 1/1.7-inch sized 12.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Below you can see the MX-1 and P330 sensor size comparison.
Pentax MX-1 and Nikon P330 have the same sensor sizes so they will provide same level of control over the depth of field when used with 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. Pentax MX-1 and Nikon P330 sensors have been tested by DxO and the results show that P330 has a better overall score of 54, 5 points higher compared to MX-1's score of 49.
