Normally, it is tough to see the contrast between sensor sizing merely by going over technical specs. The visual underneath might provide you a better sense of the sensor measurements in the 645D and K-S2.

As you have seen, the 2 cameras offer different megapixels and different sensor sizing. The 645D having a bigger sensor will make getting bokeh less difficult and the Pentax 645D will offer more detail with its extra 20 Megapixels. Higher resolution will help you crop photographs a little more aggressively. The older 645D is going to be disadvantaged in sensor innovation.
