As you can see, both of those cameras offer different megapixel count and different sensor dimensions. The K-3 using its larger sensor will make achieving bokeh less difficult and the Pentax K-3 will provide more detail having an extra 10MP. Greater resolution can also allow you to crop photos a little more aggressively. The younger K-3 is going to have an advantage when it comes to sensor innovation.
