Normally, it's difficult to visualise the contrast in sensor measurements just by looking through technical specs. The visual below may provide you a much better sense of the sensor sizing in the H90 and RX10 III.

As you can tell, both of these cameras offer different megapixel count and different sensor measurements. The H90 having a smaller sensor will make achieving shallower DOF harder and the Sony RX10 III will render more detail with its extra 8MP. Higher resolution can also let you crop shots a little more aggressively. The older H90 will be disadvantaged when it comes to sensor innovation.
