Normally, it is very difficult to envision the difference between sensor sizing merely by reading through specifications. The graphic below should provide you a more clear sense of the sensor sizing in the S640 and RZ10.

To sum up, the two cameras enjoy the same exact sensor sizing but not the same MP. You should expect to see the Pentax RZ10 to resolve greater detail due to its extra 2 Megapixels. Greater resolution will also enable you to crop images far more aggressively. The older S640 is going to be behind when it comes to sensor innovation.
