Panasonic G1 has a
12.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor . On the other hand, Panasonic G6 has a
16.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor .
Below you can see the G1 and G6 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic G1 and Panasonic G6 Cameras
Panasonic G1 and Panasonic G6 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. On the other hand, since Panasonic G1 has 32% larger pixel area compared to Panasonic G6, it has potential to collect more light on pixel level hence have less noise in low light / High ISO images.
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 G1 and Panasonic G6 sensors have been tested by DxO and the results show that G6 has a better overall score of 61, 8 points higher compared to G1's score of 53.

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
Panasonic G1
or the
Panasonic G6 ,
including hyperfocal distance.
