Usually, it can be hard to visualize the difference between sensor sizes just by looking at a spec sheet. The image here may give you a greater sense of the sensor measurements in the GX9 and A6600.

Clearly, both of the cameras feature different megapixel count and different sensor sizes. The GX9 featuring a tinier sensor is going to make getting shallower depth of field harder and the Sony A6600 will resolve extra detail having its extra 4MP. Greater resolution can also make it easier to crop pics way more aggressively. The more aged GX9 is going to be disadvantaged in sensor technology.
