Both Samsung SL102 and Panasonic GH5S have 10.0 MP resolution sensors but Samsung SL102's sensor is 1/2.3-inch (6.08 x 4.56 mm ) and Panasonic GH5S's sensor is Four Thirds (17.3 x 13 mm ).
Since Panasonic GH5S'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 Samsung SL102.
One other difference between these two cameras that is worth mentioning is that Panasonic GH5S's sensor doesn't have an anti-alias (Low-Pass) filter. Removing anti-alias filter increases the sharpness and level of detail but at the same time, it increases the chance of moiré occurring in certain scenes.
Below you can see the SL102 and GH5S sensor size comparison.

As seen above, Panasonic GH5S has a 8.1x Larger sensor area than Samsung SL102. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in 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
Samsung SL102
or the
Panasonic GH5S ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/2.3-inch versus Four Thirds),
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.
