There's an interesting rumor that says AMD is building an ARM SoC for OEMs...

Didn't they build the architecture and then chuck it?

I think they grafted 4 and 8 cortex a57 in to a package and it didn’t seem to have much market interest.

I too have heard that they have their own ARM micro architecture project though

Just wait for virtualization on M1 Mac.

That’s useful if you’re not averse to MacOS. Given that Apple now deploys backdoors by default for their own apps which will always inevitably result in exploits, and turning their back on decades of computing history with no “legacy” Heck, my 2015 MBP is still running Mojave (and thankfully still receiving software updates)

You're talking about the certificate revocation check that bypasses VPNs? That one is to prevent malware from being able to hijack and block certificate checks.

The removing of 32bit support in Catalina was definitely a bad thing for many, who are using x86-Macs, but for someone interesting in an ARM-based Mac, shouldn't play a role.

Nice hardware, but if I order a hundred, how many will I get? Arm servers so far have been vaporware, only available in single-digit quantities after a very long wait. There is a new announcement every half year or so by one firm or the other. But we've never managed to get beyond getting a sample, and not for a lack of trying. Numbers just aren't available, models change extremely fast, producers go bancrupt. Maybe…

Like Amazon? You know you can get an ARM server there any day of the week for extremely reasonable prices? Edit: to clarify, I mean on AWS, not from the Amazon store.

Reasonable is relative to what you want to do: Cloud instances are only cheap if your machines are usually idle, and you overprovisioned your datacenter massively. Cloud instances are only cheap if there is no great amount of output/input data to transfer like simulation results or large model input datasets. Cloud instances are only cheap if you don't need assurances about locality or security for compliance. Cloud instances are only cheap if you can live with a slow network between the instances, as soon as you want Infiniband or at least dedicated Ethernet links, you are either out of luck or in "really expensive" territory again.

Runs Linux natively it seems: https://www.phoronix.com/scan.php?page=article&item=ampere-a...

Wow. Never knew Linux architecture allowed it to scale on hardware in such a way. Edit : I know Linux is customized to run on a variety of hardware, I was just pointing out that I never knew you could install Ubuntu on the mentioned hardware and have it take advantage of the available hardware, given that it has specialized hardware.

Most (> 98%?) supercomputers run Linux. Has been so for many years.

These things look awesome, but are pretty expensive, still. I'd love to put an ARM server in my homelab, but the price range between 100$ (RPi & Co) and 10000$ (enterprise server) seems pretty empty right now :/

I built my home compute cluster out of four Odroid N2. These are $80 ARM based single board computers (SBC's), similar to Raspberry Pi's. You can bridge the gap between high and low ends buy buying low end and scaling horizontally.

The troublesome piece is, of course, the horizontal scaling. For a cluster of ARM CPUs to be worthwhile, you need a job that can be parallelized, but not so massively parallel that it already runs on a GPU.

Even so, I think there's a lot of potential for these low end ARM devices. Ultimately, their impact on x86 could be the same as what x86 did to the previous generation of mini computers.

> shouldn't play a role.

Until it does. Some future MacOS may need support of some new architecture feature, then it'll be "better buy an Arm13 mac if you want to run MacOS 2023!". Apple doesn't have a very good track record about supporting their own old hardware in new MacOS releases. Several iMacs and MacMinis come to mind. Their past behaviour sets a benchmark for their future behaviour, and since there are no reliable assurances about their support roadmap, I'd think carefully...

You can get SolidRun HoneyComb[0] for ~$1000, it has 16 cores with supposedly reasonable performance.
