Canon 750D has a
24.0MP APS-C (22.3 x 14.9 mm ) sized CMOS sensor and features DIGIC 6 processor. On the other hand, Sony RX10 has a
20.0MP 1-inch (13.2 x 8.8 mm ) sized BSI-CMOS sensor and features Bionz X processor.
Below you can see the 750D and RX10 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon 750D and Sony RX10 Cameras
As seen above, Canon 750D has a 2.9x Larger sensor area than Sony RX10. 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.
DxOMark Sensor Scores
Both Canon 750D and Sony RX10 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, 750D has scored 71, 2 points higher than RX10.

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 750D
or the
Sony RX10 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(APS-C versus 1-inch),
so compare them at the same framing rather than the same focal length.
Put the same focal length on the smaller sensor and it will show less depth of
field, not more, because it also crops tighter. The calculator shows the
full frame equivalent focal length for each body so you can match the framing.
