Nikon P7100 has a
10.0MP 1/1.7-inch (7.44 x 5.58 mm ) sized CCD sensor and features Expeed C2 processor. On the other hand, Canon G16 has a
12.0MP 1/1.7-inch (7.44 x 5.58 mm ) sized BSI-CMOS sensor and features Digic 6 processor.
Below you can see the P7100 and G16 sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon P7100 and Canon G16 Cameras
Nikon P7100 and Canon G16 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 Nikon P7100 has 20% larger pixel area compared to Canon G16, 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. Nikon P7100 and Canon G16 sensors have been tested by DxO and the results show that G16 has a better overall score of 54, 13 points higher compared to P7100's score of 41.

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
Nikon P7100
or the
Canon G16 ,
including hyperfocal distance.
