Nikon P7000 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, Nikon P7700 has a
12.0MP 1/1.7-inch (7.44 x 5.58 mm ) sized CMOS sensor .
Below you can see the P7000 and P7700 sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon P7000 and Nikon P7700 Cameras
Nikon P7000 and Nikon P7700 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 P7000 has 20% larger pixel area compared to Nikon P7700, 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 P7000 and Nikon P7700 sensors have been tested by DxO and the results show that P7700 has a better overall score of 53, 14 points higher compared to P7000's score of 39.

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 P7000
or the
Nikon P7700 ,
including hyperfocal distance.
