Ricoh WG-6 has a 20.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor . On the other hand, Samsung CL80 has a 14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor .
Ricoh WG-6's sensor provides 6MP more than Samsung CL80'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 WG-6 and CL80 sensor size comparison.
Ricoh WG-6 and Samsung CL80 have sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture.
