Sony RX1R III has a
61.0MP Full frame (35.8 x 23.8 mm ) sized BSI-CMOS sensor and features Bionz XR processor. On the other hand, Leica Q3 Monochrom has a
60.0MP Full frame (36 x 24 mm ) sized BSI-CMOS sensor and features Maestro IV processor.
Another similarity between these two cameras is that both Leica Q3 Monochrom and Sony RX1R III sensors lack anti-alias (Low-Pass) filters. Removing anti-alias filter increases the sharpness and level of detail but at the same time, it increases the chance of moiré occurring in certain scenes.
Below you can see the RX1R III and Q3 Monochrom sensor size comparison.

Sony RX1R III and Leica Q3 Monochrom 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.
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
Sony RX1R III
or the
Leica Q3 Monochrom ,
including hyperfocal distance.
