Thank you for your answer. I'd like to precise that the 2 RAMdisks weren't built from exactly the same set of files. There's a small difference between these RAMdisks as one of them was generated after replacing only one filewith another file which is supposed to be exactly the same as the first one. So, at the end of the day, these RAMdisks should have the same size but that isn't the case. I

No, they should not. They should probably have the same content on a file system level, but when erasing a file and replacing it by another one (or even an identical copy) you will have other file system blocks used, other inode and free block lists, etc. In other words, the binary images of the file systems will be different. They will most probably also compress to different sizes, then.

precise that I'm not the person who generated these RAMdisks, that's why I try to understand why there's such a difference betw een them. Moreover, in the messages displayed on the screen when the

They are different images, with different sizes.

They are computed based on the ramdisk sizes (plus some rounding). Given different ramdisk sizes you end up with different load addresses. There is no magic anywhere here.
