Canon R5 has a
45.0MP Full frame (36 x 24 mm ) sized CMOS sensor and features Digic X processor. On the other hand, Sony A450 has a
14.0MP APS-C (23.4 x 15.6 mm ) sized CMOS sensor and features Bionz processor.
Canon R5's sensor provides 31MP more than Sony A450'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 R5 and A450 sensor size comparison.
As seen above, Canon R5 has a 2.4x Larger sensor area than Sony A450. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in same focal length and aperture.
