It got more AES encryption power than the previous generation.

And it may likely have more AES encryption power than x86-64.

But I don't think AES encryption is really a bottleneck on
servers in general today, so the practical impact will
be pretty small.

So they can do 2 PB and x86-64 can only do 256 TB. So they can totally
sit on the market for systems with 256 TB to 2 PB memory.

But that market is very much niche.
