Normally, it's difficult to picture the difference between sensor sizes only by checking specifications. The image here should provide you a far better sense of the sensor sizes in the E-M5 II and K100D S.

Plainly, both cameras come with different resolutions and different sensor sizes. The E-M5 II because of its tinier sensor is going to make shooting bokeh harder and the Olympus E-M5 II will give more detail as a result of its extra 10MP. Higher resolution can also enable you to crop shots a good deal more aggressively. The more modern E-M5 II provides an edge in sensor technology.
