Normally, it is very hard to imagine the difference between sensor measurements simply by checking specifications. The photograph here may give you a much better sense of the sensor sizing in the TS20 and 645Z.

To sum up, each of the cameras provide different megapixel count and different sensor measurements. The TS20 having a tinier sensor is going to make shooting shallower DOF more difficult and the Pentax 645Z will give you greater detail because of its extra 35 Megapixels. Greater resolution will also make it easier to crop photos more aggressively. The older TS20 is going to be disadvantaged with regard to sensor innovation.
