Both Canon 100D and Canon 700D have APS-C sized 18.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Below you can see the 100D and 700D sensor size comparison.
Canon 100D and Canon 700D 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.
