Both Canon 7D and Canon 600D 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 7D and 600D sensor size comparison.
Canon 7D and Canon 600D 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.
