Generally, it is very tough to envision the gap between sensor measurements purely by looking at a spec sheet. The visual underneath might give you a clearer sense of the sensor dimensions in the TG-860 and K-1.

As you can see, the 2 cameras enjoy different resolutions and different sensor measurements. The TG-860 because of its tinier sensor will make achieving shallower DOF tougher and the Pentax K-1 will give greater detail due to its extra 20 Megapixels. Greater resolution will also help you crop pics far more aggressively. The older TG-860 is going to be disadvantaged when it comes to sensor technology.
