Canon 5D MII has a
21.0MP Full frame (36 x 24 mm ) sized CMOS sensor and features Digic 4 processor. On the other hand, Canon RP has a
26.0MP Full frame (35.9 x 24 mm ) sized CMOS sensor and features Digic 8 processor.
Canon RP's sensor provides 5MP more than Canon 5D MII'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 5D MII and EOS RP sensor size comparison.
Canon 5D MII and Canon RP have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the 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. Canon 5D MII and Canon RP sensors have been tested by DxO and the results show that EOS RP has a better overall score of 85, 6 points higher compared to 5D MII's score of 79.
