Oftentimes, it's tough to visualise the contrast between sensor measurements purely by reviewing technical specs. The photograph underneath should provide you a better sense of the sensor sizes in the XG-1 and RX100 III.

As you can tell, both of these cameras posses different resolutions and different sensor measurements. The XG-1 using its tinier sensor will make getting shallow depth of field more challenging and the Sony RX100 III will offer more detail because of its extra 4MP. Greater resolution can also make it easier to crop images somewhat more aggressively.
