Normally, it's tough to visualise the difference in sensor measurements purely by researching technical specs. The visual below will give you a greater sense of the sensor dimensions in the GX8 and A6600.

As you have seen, both cameras have different resolutions and different sensor measurements. The GX8 due to its smaller sensor will make shooting shallower depth of field more difficult and the Sony A6600 will provide you with extra detail as a result of its extra 4 Megapixels. Greater resolution can also make it easier to crop images a bit more aggressively. The older GX8 will be behind when it comes to sensor innovation.
