Generally, it is very difficult to envision the contrast in sensor sizes merely by checking out a spec sheet. The image here should offer you a more clear sense of the sensor sizes in the TG-870 and K10D.

As you can see, each of these cameras come with different resolutions and different sensor sizes. The TG-870 using its smaller sensor will make achieving bokeh more difficult and the Olympus TG-870 will produce extra detail with its extra 6MP. Higher resolution will also let you crop shots a good deal more aggressively. The more recent TG-870 is going to have an advantage when it comes to sensor tech.
