In many cases, it is very difficult to see the difference in sensor measurements only by looking through specifications. The photograph here will offer you a better sense of the sensor sizes in the GX7 and ZS20.

To sum up, both of the cameras come with different resolutions and different sensor measurements. The GX7 because of its larger sensor will make getting shallower DOF simpler and the Panasonic GX7 will render extra detail as a result of its extra 2MP. Greater resolution can also enable you to crop images a good deal more aggressively. The more recent GX7 is going to have a benefit in sensor tech.
