Both Olympus E-PL7 and Panasonic GF6 have 16.0 MP resolution sensors but Olympus E-PL7's sensor is Four Thirds (17.3 x 13 mm ) and Panasonic GF6's sensor is Four Thirds (17.3 x 13 mm ).
Since Panasonic GF6'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 Olympus E-PL7.
Below you can see the E-PL7 and GF6 sensor size comparison.
Olympus E-PL7 and Panasonic GF6 have the same sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture.
