Normally, it is very difficult to visualize the contrast in sensor dimensions only by going through specifications. The pic below might offer you a far better sense of the sensor sizing in the 645D and K-1 II.

Plainly, each of these cameras enjoy different megapixel count and different sensor dimensions. The 645D due to its larger sensor is going to make achieving shallow depth of field easier and the Pentax 645D will show more detail having its extra 4 Megapixels. Greater resolution will enable you to crop images far more aggressively. The more aged 645D will be disadvantaged with regard to sensor innovation.
