In many cases, its hard to visualise the gap in sensor sizing only by looking through a spec sheet. The graphic here will help give you a stronger sense of the sensor dimensions in the 5010 and K20D.

Clearly, both of these cameras posses different megapixel count and different sensor sizing. The 5010 having a smaller sensor will make shooting shallow depth of field trickier and the Pentax K20D will result in more detail with its extra 1MP. Greater resolution will make it easier to crop images somewhat more aggressively. The more modern 5010 is going to have a benefit with regard to sensor tech.
