Typically, it's difficult to visualise the gap between sensor measurements just by reviewing technical specs. The visual underneath will help provide you a much better sense of the sensor sizing in the E-M1 and W620.

As you have seen, both cameras come with different resolutions and different sensor measurements. The E-M1 because of its larger sensor will make achieving shallower depth of field less difficult and the Olympus E-M1 will deliver more detail as a result of its extra 2 Megapixels. Greater resolution can also make it easier to crop images a good deal more aggressively. The younger E-M1 will have an advantage when it comes to sensor innovation.
