Panasonic FZ1000 II has a 20.0MP 1″ (13.2 x 8.8 mm ) sized BSI-CMOS sensor and features Venus Engine 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 6MP more than Panasonic FZ1000 II'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 FZ1000 II and EOS RP sensor size comparison.
