Usually, it's difficult to see the difference in sensor sizes only by checking out specifications. The picture below will provide you a more clear sense of the sensor measurements in the E-PM1 and GM1.

Plainly, both cameras provide the same sensor dimensions albeit not the same resolution. You can expect the Panasonic GM1 to produce extra detail due to its extra 4 Megapixels. Higher resolution will also make it easier to crop shots more aggressively. The more aged E-PM1 will be disadvantaged when it comes to sensor technology.
