Hi,
Let's answer this question as the command vary between Software codes and not hardware model.
Some of the command which are related to Multiple Core outputs are the only difference on the basis of the Hardware Model and rest would vary with the software code and you can check Cisco ASA command Reference for that:-
http://www.cisco.com/c/en/us/support/security/asa-5500-series-next-generation-firewalls/products-command-reference-list.html
Also , ASA 5500 Series cannot go above 9.1 code.
For Ex:- show cpu <Core ID> was only added for the X-Series:-
