Both Panasonic LX5 and Ricoh CX6 have 10.0 MP resolution sensors but Panasonic LX5's sensor is 1/1.63-inch (8.07 x 5.56 mm ) and Ricoh CX6's sensor is 1/2.3-inch (6.17 x 4.55 mm ).
Since Panasonic LX5'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 Ricoh CX6.
Below you can see the LX5 and CX6 sensor size comparison.

As seen above, Panasonic LX5 has a 1.6x Larger sensor area than Ricoh CX6. 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
Panasonic LX5
or the
Ricoh CX6 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/1.63-inch 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.
