I remember when Microsoft announced Windows on Arm 2 years ago. Now in 2019 they still haven't delivered. I couldn't care less about performance because there are no ARM products on the market that are actually interesting to early adopters. Even if we take alternative routes that weren't intended for mainstream customers, for example arm SBCs. After 2 years literally only the RK3399 SoC which was basically intended for chromebooks anyway, so ARM contributed 0% to it's success, has actually offered extremely basic features like PCIe. But thanks to the raspberry pi monoculture nobody is working on things like GPU drivers or better software support for SBCs anyway. Your crappy A11X or whatever with nice artifcal benchmark scores doesn't interest me. It's a shut in that can't communicate with the outside world and barely competes with an obsolete i5 3540 from 2012.

There is a reason nothing happens and it's because most companies don't care about ARM in the server space at all (including ARM themselves), they only want to use it to negotiate better discounts with intel. So far Google is the only company that has ARM based computers.
