Generally, it is tough to imagine the difference between sensor measurements merely by going over technical specs. The visual below will help give you a far better sense of the sensor sizing in the 40D and K20D.

As you can tell, each of the cameras have the same sensor dimensions albeit different MP. You can count on the Pentax K20D to deliver greater detail because of its extra 5 Megapixels. Higher resolution can also allow you to crop photographs a bit more aggressively. The older 40D is going to be behind with regard to sensor technology.
