Canon RP has a
26.0MP Full frame (35.9 x 24 mm ) sized CMOS sensor and features Digic 8 processor. On the other hand, Sony A1 has a
50.0MP Full frame (35.9 x 24 mm ) sized Stacked CMOS sensor and features Dual Bionz XR processor.
Sony A1's sensor provides 24MP more than Canon RP'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 EOS RP and A1 sensor size comparison.
Canon RP and Sony A1 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 Canon RP has 91% larger pixel area compared to Sony A1, 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. Canon RP and Sony A1 sensors have been tested by DxO and the results show that A1 has a better overall score of 98, 13 points higher compared to EOS RP's score of 85.
