Dynamic CRM 2016 VS dynamic AX 2016 (AX7)

Dear Experts,

I really want to know the main differences between Dynamic CRM 2016 VS dynamic AX 2016 (AX7), i was reading a lot of articles on the websites but all of them is old, and the new AX 7 have a lot of the features than previous versions like (cloud deployment, UI(UX) and Responsive application on tablet and integration with office 365).

I will be appreciated for your feedback.

Thanks
