Oftentimes, it is very difficult to visualise the difference between sensor sizing purely by checking technical specs. The graphic here will help provide you a stronger sense of the sensor dimensions in the TG-320 and GR III.

As you can tell, the two cameras offer different megapixels and different sensor sizing. The TG-320 featuring a tinier sensor will make achieving shallower DOF trickier and the Ricoh GR III will give you extra detail due to its extra 10 Megapixels. Higher resolution will allow you to crop photographs a little more aggressively. The older TG-320 is going to be behind when it comes to sensor innovation.
