Canon R3 has a
24.0MP Full frame (36 x 24 mm ) sized Stacked CMOS sensor and features Digic X 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.
Below you can see the R3 and EOS RP sensor size comparison.
Sensor Size and Resolution Comparison image of Canon R3 and Canon RP Cameras
Canon R3 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
Both Canon R3 and Canon RP sensors have been tested by DxoMark. DxoMark 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. Of the two cameras that we are comparing, R3 has scored 96, 11 points higher than EOS RP.

Sensor size sets the circle of confusion, so it drives how much depth of field each
of these bodies gives you at a given aperture. You can calculate it exactly for the
Canon R3
or the
Canon RP ,
including hyperfocal distance.
