Normally, it can be tough to visualize the difference in sensor dimensions merely by seeing technical specs. The picture underneath will give you a more clear sense of the sensor sizes in the E-510 and NX20.

As you have seen, both cameras provide different megapixel count and different sensor dimensions. The E-510 due to its smaller sensor is going to make shooting bokeh tougher and the Samsung NX20 will produce greater detail utilizing its extra 10MP. Higher resolution can also make it easier to crop photographs more aggressively. The more aged E-510 will be behind in sensor tech.
