Normally, it is very hard to visualize the gap between sensor sizing merely by looking at a spec sheet. The photograph underneath may give you a clearer sense of the sensor dimensions in the SP-620 UZ and RX100 IV.

Clearly, both cameras have different megapixel count and different sensor sizing. The SP-620 UZ having a tinier sensor is going to make getting shallow DOF more challenging and the Sony RX100 IV will resolve more detail using its extra 4MP. Higher resolution will allow you to crop pictures a bit more aggressively. The older SP-620 UZ is going to be behind in sensor tech.
