Typically, it's hard to visualise the difference in sensor measurements merely by viewing specs. The visual here might offer you a far better sense of the sensor sizing in the G9 and A6400.

All in all, the two cameras offer different megapixels and different sensor measurements. The G9 because of its smaller sensor will make getting shallow depth of field trickier and the Sony A6400 will result in extra detail having its extra 4 Megapixels. Higher resolution will make it easier to crop pictures a little more aggressively. The older G9 will be disadvantaged in sensor innovation.
