Usually, it is very hard to envision the gap between sensor measurements purely by reading through a spec sheet. The graphic here might offer you a clearer sense of the sensor sizes in the RX100 IV and W320.

Clearly, both of the cameras have got different megapixels and different sensor measurements. The RX100 IV because of its larger sensor will make shooting shallow DOF easier and the Sony RX100 IV will resolve greater detail having its extra 6 Megapixels. Greater resolution will make it easier to crop images much more aggressively. The newer RX100 IV is going to have an edge in sensor innovation.
