Usually, it is difficult to picture the gap in sensor measurements purely by researching technical specs. The graphic below may give you a better sense of the sensor dimensions in the WG-2 GPS and RX10 IV.

As you can tell, both of the cameras come with different megapixels and different sensor measurements. The WG-2 GPS because of its smaller sensor is going to make achieving shallow depth of field tougher and the Sony RX10 IV will provide you with greater detail utilizing its extra 4 Megapixels. Higher resolution can also allow you to crop pictures a good deal more aggressively. The older WG-2 GPS will be disadvantaged when it comes to sensor technology.
