In many cases, its tough to see the difference in sensor dimensions simply by seeing technical specs. The pic below will provide you a better sense of the sensor sizes in the E-P3 and GM5.

As you can tell, the 2 cameras have the same sensor dimensions albeit not the same resolution. You can count on the Panasonic GM5 to show more detail having its extra 4 Megapixels. Higher resolution will make it easier to crop shots a bit more aggressively. The more aged E-P3 will be behind with regard to sensor innovation.
