In many cases, its hard to visualise the gap between sensor sizing only by going over specs. The visual here will offer you a greater sense of the sensor measurements in the K20D and W650.

As you can plainly see, the 2 cameras feature different megapixel count and different sensor sizing. The K20D because of its bigger sensor will make achieving shallow depth of field simpler and the Sony W650 will offer you greater detail as a result of its extra 1 Megapixels. Higher resolution can also help you crop shots way more aggressively. The older K20D is going to be behind in sensor tech.
