Both Canon T7 and Canon 760D have APS-C sized 24.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Below you can see the T7 and 760D sensor size comparison.
Sensor Size and Resolution Comparison image of Canon T7 and Canon 760D Cameras
Canon T7 and Canon 760D 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.
DxOMark Sensor Scores
Both Canon T7 and Canon 760D 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, T7 has scored 71, 1 points higher than 760D.

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 T7
or the
Canon 760D ,
including hyperfocal distance.
