In many cases, it's difficult to visualise the gap in sensor dimensions simply by going through specs. The pic here will give you a more clear sense of the sensor dimensions in the E-P3 and GM1.

All in all, both of the cameras have got the exact same sensor measurements but not the same megapixels. You can expect to see the Panasonic GM1 to produce greater detail due to its extra 4MP. Greater resolution will make it easier to crop photos much more aggressively. The more aged E-P3 will be disadvantaged with regard to sensor innovation.
