Quite often, its tough to visualise the difference between sensor measurements only by looking at specs. The visual here may provide you a clearer sense of the sensor sizes in the WG-1 GPS and RX100 III.

All in all, both the cameras come with different megapixel count and different sensor measurements. The WG-1 GPS with its tinier sensor will make getting shallower depth of field harder and the Sony RX100 III will resolve extra detail with its extra 6 Megapixels. Higher resolution can also enable you to crop photographs a good deal more aggressively. The older WG-1 GPS is going to be disadvantaged in sensor tech.
