Both Nikon S9500 and Sony HX90V have 18.0 MP resolution sensors but Nikon S9500's sensor is 1/2.3-inch (6.16 x 4.62 mm ) and Sony HX90V's sensor is
Since Nikon S9500'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 Sony HX90V.
Below you can see the S9500 and HX90V sensor size comparison.

Nikon S9500 and Sony HX90V 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
Nikon S9500
or the
Sony HX90V ,
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.
