Typically, it's difficult to envision the contrast in sensor measurements just by looking through a spec sheet. The photograph underneath will offer you a better sense of the sensor sizing in the 645D and RX100 VII.

Clearly, both cameras enjoy different megapixel count and different sensor measurements. The 645D using its bigger sensor will make getting shallow DOF easier and the Pentax 645D will provide you with more detail because of its extra 20 Megapixels. Higher resolution can also help you crop photographs far more aggressively. The older 645D will be behind with regard to sensor tech.
