Both Canon 7D MII and Sony HX300 have 20.0 MP resolution sensors but Canon 7D MII's sensor is APS-C (22.4 x 15 mm ) and Sony HX300's sensor is 1/2.3-inch (6.16 x 4.62 mm ).
Since Canon 7D MII'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 HX300.
Below you can see the 7D MII and HX300 sensor size comparison.

As seen above, Canon 7D MII has a 11.8x Larger sensor area than Sony HX300. 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
Canon 7D MII
or the
Sony HX300 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(APS-C versus 1/2.3-inch),
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.
