All in all, the 2 cameras have different megapixel count and different sensor sizing. The RX100 having a bigger sensor will make achieving shallow DOF less difficult and the Sony RX100 will resolve greater detail with its extra 2MP. Higher resolution will allow you to crop pictures a bit more aggressively. The older RX100 is going to be disadvantaged when it comes to sensor tech.
