Sometimes, it is very tough to imagine the difference between sensor sizes merely by reading through a spec sheet. The picture below will provide you a greater sense of the sensor sizes in the 645Z and HX100V.

As you can see, both the cameras have different megapixel count and different sensor sizes. The 645Z using its larger sensor is going to make getting shallower DOF less difficult and the Pentax 645Z will resolve more detail having an extra 35MP. Greater resolution can also let you crop images a bit more aggressively. The newer 645Z provides an advantage when it comes to sensor innovation.
