Both Canon SX60 HS and Panasonic FZ70 have 16.0 MP resolution sensors but Canon SX60 HS's sensor is 1/2.3 (6.17 x 4.55 mm ) and Panasonic FZ70's sensor is 1/2.3-inch (6.17 x 4.55 mm ).
Since Panasonic FZ70'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 SX60 HS.
Below you can see the SX60 HS and FZ70 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon SX60 HS and Panasonic FZ70 Cameras
Canon SX60 HS and Panasonic FZ70 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
DxOMark is a benchmark that scientifically assesses image quality of camera sensors. It 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. Canon SX60 HS and Panasonic FZ70 sensors have been tested by DxO and the results show that FZ70 has a better overall score of 41, 2 points higher compared to SX60 HS's score of 39.

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 SX60 HS
or the
Panasonic FZ70 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/2.3 versus 1/2.3-inch),
so compare them at the same framing rather than the same focal length.
Put the same focal length on the smaller sensor and it will show less depth of
field, not more, because it also crops tighter. The calculator shows the
full frame equivalent focal length for each body so you can match the framing.
