Often, its difficult to imagine the difference between sensor sizing purely by reviewing a spec sheet. The photograph below may give you a more clear sense of the sensor sizing in the EX-Z270 and K20D.

As you can see, both of the cameras feature different megapixels and different sensor sizing. The EX-Z270 because of its tinier sensor is going to make achieving shallower depth of field more difficult and the Pentax K20D will offer you more detail due to its extra 5 Megapixels. Greater resolution will also make it easier to crop photos way more aggressively. The fresher EX-Z270 should have an edge in sensor technology.
