Case 8420 vs NH 630

Been baling several years with a case 8420 and was looking to go to a little larger baler.

My question is how much bigger of a bale does the nh 630 bale than the 8420. I know the dimensions of the 8420 is 39x52” and the 630 is a true 4x4 but wasn’t sure about bale density.
Will there be much difference in bale weight?

I’m hoping to put more hay in the same space and not have to put out hay as often.
