Pentax K-S1 vs Pentax P80 Sensor Comparison

Oftentimes, it's tough to visualize the gap between sensor sizes just by reading through a spec sheet. The image here will provide you a more clear sense of the sensor sizing in the K-S1 and P80.

As you can see, both of those cameras come with different megapixel count and different sensor sizes. The K-S1 with its larger sensor is going to make achieving bokeh less difficult and the Pentax K-S1 will give you greater detail because of its extra 8MP. Greater resolution will enable you to crop images a good deal more aggressively. The fresher K-S1 should have an advantage with regard to sensor tech.
