In many cases, it can be difficult to see the gap in sensor measurements purely by viewing specifications. The graphic below may give you a more clear sense of the sensor dimensions in the X70 and a5100.

Plainly, both of those cameras feature different megapixel count and different sensor measurements. The X70 having a smaller sensor will make achieving bokeh more difficult and the Sony a5100 will render greater detail with its extra 12MP. Greater resolution will make it easier to crop pics way more aggressively. The older X70 will be behind with regard to sensor innovation.
