They have to make a server-class chip if they want to have something like the Mac Pro on ARM too. To actually go into the server business they might have to add a bit more I/O capability like Epyc vs. Threadripper, but the basic cpu should be more than up to it, if it has 32 performance cores or more. Even just a rack-mounted M1 would be interesting for many server applications and anything above more so.
