Pentax K20D vs Sony HX100V Sensor Comparison
Often, it is hard to imagine the difference between sensor sizing only by checking specifications. The graphic underneath should give you a better sense of the sensor sizes in the K20D and HX100V.
To sum up, both of the cameras have got different megapixel count and different sensor sizing. The K20D using its bigger sensor is going to make achieving shallow DOF less difficult and the Sony HX100V will resolve greater detail with its extra 1 Megapixels. Higher resolution will also make it easier to crop shots much more aggressively. The older K20D is going to be disadvantaged when it comes to sensor innovation.
