More often than not, it can be tough to visualise the gap between sensor dimensions merely by checking a spec sheet. The picture below may provide you a better sense of the sensor dimensions in the RZ10 and A6400.

As you can see, both of these cameras come with different megapixel count and different sensor dimensions. The RZ10 using its tinier sensor will make achieving shallower depth of field more difficult and the Sony A6400 will give greater detail because of its extra 10 Megapixels. Greater resolution will also enable you to crop pics a good deal more aggressively. The more aged RZ10 is going to be behind when it comes to sensor tech.
