Nikon D80 has a 10.0MP APS-C (23.6 x 15.8 mm ) sized CCD sensor . On the other hand, Ricoh GR has a 16.0MP APS-C (23.7 x 15.7 mm ) sized CMOS sensor .
Ricoh GR's sensor provides 6MP more than Nikon D80's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Below you can see the D80 and GR sensor size comparison.

Sensor Size and Resolution Comparison image of Nikon D80 and Ricoh GR Cameras
Nikon D80 and Ricoh GR have almost the same sensor size so none of them has any significant advantage over other in providing control over 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. Nikon D80 and Ricoh GR sensors have been tested by DxO and the results show that GR has a better overall score of 78, 17 points higher compared to D80's score of 61.
