Typically, it's tough to visualise the contrast between sensor sizing just by going over specifications. The visual here will provide you a stronger sense of the sensor sizing in the GX7 and K100D.

Plainly, each of the cameras provide different resolutions and different sensor sizing. The GX7 using its tinier sensor will make shooting bokeh more challenging and the Panasonic GX7 will deliver extra detail having an extra 10 Megapixels. Greater resolution will also enable you to crop photos more aggressively. The fresher GX7 is going to have a benefit when it comes to sensor technology.
