Discussion with Alberto has been repeatedly proven impossible in the past.

Agreed. But you'll never find a set of benchmarks that will satisfy everybody :-)

A thing that is sure is that Apple chips have never been used publicly as server chips,
and the sets of benchmarks that we have seen doesn't prove they would be any good, or
bad, at that. You can't even run JIT workloads (Java) on iOS (except for Apple provided
Javascript engine).

Those micro-architectural features are interesting but they don't tell the whole story.
What I'd like to see is an Apple chip with an OS not as restrictive as iOS is. That
would enable the community to run any kind of program.

OTOH any comparison that has been made of Apple vs competition, Intel or other ARM
vendors, all show that the Apple micro-arch is really good.
