As you can tell, both cameras feature different megapixel count and different sensor measurements. The WG-3 with its smaller sensor will make achieving bokeh trickier and the Sony RX10 III will result in extra detail using its extra 4MP. Greater resolution can also make it easier to crop photos way more aggressively. The older WG-3 will be behind when it comes to sensor technology.
