Usually, it is very hard to see the difference in sensor measurements merely by viewing specifications. The graphic below may give you a far better sense of the sensor measurements in the A9 II and RX100.

Plainly, both of these cameras have different resolutions and different sensor measurements. The A9 II using its bigger sensor will make achieving shallow depth of field less difficult and the Sony A9 II will result in more detail having an extra 4MP. Higher resolution can also enable you to crop shots a bit more aggressively. The newer A9 II will have a benefit in sensor innovation.
