Both Leica M9-P and Leica M9 have Full frame sized 18.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Another similarity between these two cameras is that both Leica M9 and Leica M9-P sensors lack anti-alias (Low-Pass) filters. Removing anti-alias filter increases the sharpness and level of detail but at the same time, it increases the chance of moiré occurring in certain scenes.
Below you can see the M9-P and M9 sensor size comparison.

Leica M9-P and Leica M9 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. Leica M9-P and Leica M9 sensors have been tested by DxO and the results show that M9 has a better overall score of 69, 1 points higher compared to M9-P's score of 68.
