Both Panasonic G6 and Panasonic GH3 have Four Thirds sized 16.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Below you can see the G6 and GH3 sensor size comparison.
Panasonic G6 and Panasonic GH3 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. Panasonic G6 and Panasonic GH3 sensors have been tested by DxO and the results show that GH3 has a better overall score of 71, 10 points higher compared to G6's score of 61.
