As you can see, both of these cameras offer different megapixels and different sensor sizing. The NX20 due to its smaller sensor is going to make shooting bokeh harder and the Sony A900 will produce more detail utilizing its extra 5 Megapixels. Higher resolution will also let you crop pictures a little more aggressively. The more modern NX20 should have a benefit in sensor innovation.
