More often than not, it is very difficult to envision the gap in sensor dimensions only by viewing technical specs. The picture here might offer you a much better sense of the sensor sizes in the SZ1 and 645Z.

As you have seen, both of these cameras posses different megapixel count and different sensor dimensions. The SZ1 with its smaller sensor will make achieving bokeh tougher and the Pentax 645Z will result in extra detail because of its extra 35 Megapixels. Greater resolution will make it easier to crop photos somewhat more aggressively. The more aged SZ1 will be behind in sensor innovation.
