Normally, it can be hard to visualise the difference in sensor sizes only by looking through specifications. The picture here will help provide you a clearer sense of the sensor dimensions in the GX9 and K-3.

To sum up, both the cameras provide different resolutions and different sensor sizes. The GX9 due to its smaller sensor will make shooting shallower depth of field tougher and the Pentax K-3 will provide you with extra detail as a result of its extra 4MP. Greater resolution will allow you to crop photos more aggressively. The newer GX9 will have an edge with regard to sensor technology.
