Typically, it is very difficult to visualize the contrast between sensor measurements merely by going over specifications. The graphic here will help give you a more clear sense of the sensor measurements in the K20D and E90.

To sum up, both of the cameras have got different resolutions and different sensor measurements. The K20D having a larger sensor is going to make achieving shallow depth of field simpler and the Pentax K20D will offer you more detail using its extra 5 Megapixels. Greater resolution will allow you to crop pics much more aggressively. The older K20D is going to be behind with regard to sensor tech.
