Both Leica Q and Sony RX1 have 24.0 MP resolution sensors but Leica Q's sensor is Full frame (36 x 24 mm ) and Sony RX1's sensor is Full frame (35.8 x 23.8 mm ).
Since Leica Q'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 Sony RX1.
Below you can see the Q Typ 116 and RX1 sensor size comparison.
Leica Q and Sony RX1 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
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 Q and Sony RX1 sensors have been tested by DxO and the results show that RX1 has a better overall score of 93, 8 points higher compared to Q Typ 116's score of 85.
