It works fine, performance is good enough for most.

Judging by the performance of the AArch64 boxes provided by Shippable/Packet (using -j16 leading to a performance similar to -j3 for an x86 CI service, for the LDC CI suite, but requiring obviously a lot more memory for that throughput), I guess it's not that much better when the x86 chips are tweaked for throughput (server CPUs: lower frequencies, lower voltages, much more cores).

Amazon just announced their own custom-designed AArch64 server core for AWS:

I mentioned the Cloudflare server benchmarks against Intel earlier in this thread, comparable performance with half the electric power dissipation:

All that said, I don't think cloud will matter that much, as mobile p2p is poised to replace a lot of it.

Qualcomm just announced their ARM laptop chip for next year, the Snapdragon 8cx, alongside their latest top-end mobile chip, the 855:

This likely is a tweaked ARM Cortex-A76, which is the first chip design where ARM claims laptop performance:

https://arstechnica.com/gadgets/2018/06/arm-promises-laptop-level-performance-in-2019/

Qualcomm claims 2X the performance of an unnamed 15W Intel laptop chip when (both are?) running at 7W, and much lower power consumption overall. Not exactly apples-to-apples since they're using the latest 7nm process for their unreleased chip, but interesting claims nonetheless.

For software, Windows 10 Enterprise, Firefox, Office 365/Azure, and of course the just-announced Chromium-based Edge will all be optimized for 64-bit ARM. Microsoft released a 64-bit ARM SDK for Windows this year, so you can build native apps.

It appears that WinDragon is making a big push for ARM-based laptops over the next year or two. I think ARM will do well, as they have many other OS options, including iOS and the Samsung Android devices with multi-window DeX support. I'm skeptical about Windows surviving this ARM transition because of all the legacy cruft, but let's see.

Some more interesting server benchmarks (ARM vs. Power9 vs. x86):

The recent  ARM product of 2019 is improve for mobile. I get myself a 2019 Android phone with Qualcomm 865， the performance improve is huge compare to 2017 Android phone. (build llvm time take around 1/10 compare my old phone, I feel it will be same speed like Laptap in 1 to 3 years).

The Qualcomm 865 is based on ARM Cortex-A76,  design release at 5/31/18.  I guess the benchmark ARM 16NM server is use at least 2nd generation behind product(there is 14nm, 12nm, 10nm, 7nm ARM product). And ARM is yet not fully commit to server product yet.

Theres is so many people use mobile phone every day,  and Microsoft will release ARM based Laptop product soon, Apple prepare for ARM based New Macbook for years. The Dlang will not be able to work for the laptop product when they are released.   (And Rust/Go already ready for this.)
