Both Panasonic SZ8 and Nikon P950 have 16.0 MP resolution sensors but Panasonic SZ8's sensor is 1/2.3-inch (6.08 x 4.56 mm ) and Nikon P950's sensor is (6.17 x 4.55 mm ).
Since Nikon P950'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 Panasonic SZ8.
Below you can see the SZ8 and P950 sensor size comparison.

Panasonic SZ8 and Nikon P950 have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the 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
Panasonic SZ8
or the
Nikon P950 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/2.3-inch versus ),
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.
