Normally, its difficult to visualize the contrast in sensor sizing merely by researching a spec sheet. The photograph underneath will help provide you a greater sense of the sensor sizing in the 645D and HX1.

Clearly, the 2 cameras posses different resolutions and different sensor sizing. The 645D using its larger sensor is going to make getting shallow depth of field less difficult and the Pentax 645D will render more detail because of its extra 31 Megapixels. Greater resolution can also make it easier to crop pics somewhat more aggressively. The more modern 645D provides an advantage in sensor innovation.
