As you can plainly see, the two cameras offer different megapixels and different sensor dimensions. The K20D using its larger sensor is going to make getting shallow depth of field simpler and the Pentax K20D will give you greater detail because of its extra 3MP. Greater resolution will also enable you to crop pics a little more aggressively. The more aged K20D is going to be disadvantaged in sensor tech.
