Below you can see the SX510 HS and SX170 IS sensor size comparison.
Sensor Size and Resolution Comparison image of Canon SX510 HS and Canon SX170 IS Cameras
Canon SX510 HS and Canon SX170 IS 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.
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 SX510 HS
or the
Canon SX170 IS ,
including hyperfocal distance.
