Typically, it is very tough to imagine the difference in sensor sizing only by seeing a spec sheet. The photograph here should give you a far better sense of the sensor measurements in the 7040 and K20D.

As you can see, both the cameras feature different resolutions and different sensor sizing. The 7040 due to its smaller sensor is going to make shooting shallower depth of field more difficult and the Pentax K20D will show more detail utilizing its extra 1 Megapixels. Higher resolution will allow you to crop photographs way more aggressively. The fresher 7040 should have an edge in sensor tech.
