Both Fujifilm XP130 and Panasonic GX7 have 16.0 MP resolution sensors but Fujifilm XP130's sensor is 1/2.3 (6.17 x 4.55 mm ) and Panasonic GX7's sensor is Four Thirds (17.3 x 13 mm ).
Since Panasonic GX7'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 Fujifilm XP130.
Below you can see the XP130 and GX7 sensor size comparison.

As seen above, Panasonic GX7 has a 8.0x Larger sensor area than Fujifilm XP130. 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
Fujifilm XP130
or the
Panasonic GX7 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/2.3 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.
