How similar are chaos Beastmen to the Beastmen from Fantasy?

I make the specific wording of chaos Beastmen as I know that Beastmen are Abhumans that are capable of doing more than just serving chaos, but specifically those that worship chaos; do we know how much they adopt a similar system to Fantasy Beastmen in terms of just focusing on bringing everything to ruin, hating humans and having their own hierarchies and tribes?
