Both Canon M and Canon M10 have 18.0 MP resolution sensors but Canon M's sensor is APS-C (22.3 x 14.9 mm ) and Canon M10's sensor is APS-C (22.3 x 14.9 mm ).
Since Canon M10's has a larger sensor area with the same resolution, this means that it also has a larger pixel area hence better light collecting capacity for a given aperture compared to Canon M.
Below you can see the M and M10 sensor size comparison.
Canon M and Canon M10 have the same sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture.
