Both Nikon L810 and Fujifilm X100T have 16.0 MP resolution sensors but Nikon L810's sensor is 1/2.3-inch (6.17 x 4.55 mm ) and Fujifilm X100T's sensor is APS-C (23.6 x 15.8 mm ).
Since Fujifilm X100T'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 Nikon L810.
Below you can see the L810 and X100T sensor size comparison.

As seen above, Fujifilm X100T has a 13.3x Larger sensor area than Nikon L810. 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
Nikon L810
or the
Fujifilm X100T ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/2.3-inch versus APS-C),
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.
