Normally, it can be hard to picture the gap between sensor sizes only by reading through specs. The pic below will help offer you a clearer sense of the sensor sizing in the S1 and RX10 IV.

All in all, both of the cameras posses different resolutions and different sensor sizes. The S1 having a tinier sensor is going to make achieving shallower depth of field trickier and the Sony RX10 IV will resolve greater detail because of its extra 6 Megapixels. Higher resolution will also allow you to crop shots somewhat more aggressively. The more aged S1 is going to be disadvantaged with regard to sensor technology.
