Quite often, it is very hard to picture the contrast in sensor sizing only by seeing specifications. The photograph below might give you a more clear sense of the sensor sizing in the P80 and RX100 III.

To sum up, the two cameras enjoy different megapixel count and different sensor sizing. The P80 using its smaller sensor is going to make getting shallower DOF harder and the Sony RX100 III will provide more detail using its extra 8 Megapixels. Greater resolution will make it easier to crop images far more aggressively. The older P80 will be disadvantaged in sensor innovation.
