Usually, it's hard to envision the difference between sensor sizing purely by reviewing specs. The graphic here may offer you a clearer sense of the sensor sizes in the 645Z and K-30.

All in all, both the cameras come with different resolutions and different sensor sizing. The 645Z because of its larger sensor will make getting shallower DOF easier and the Pentax 645Z will offer you more detail due to its extra 35 Megapixels. Greater resolution can also allow you to crop images a good deal more aggressively. The fresher 645Z will have a benefit when it comes to sensor tech.
