In many cases, it is hard to see the difference between sensor dimensions merely by reading through technical specs. The picture below will provide you a clearer sense of the sensor sizing in the E-PL7 and K20D.

As you can tell, the 2 cameras feature different resolutions and different sensor dimensions. The E-PL7 due to its tinier sensor will make getting shallow depth of field more challenging and the Olympus E-PL7 will resolve extra detail due to its extra 1MP. Higher resolution can also make it easier to crop photographs way more aggressively. The more recent E-PL7 is going to have an advantage when it comes to sensor tech.
