Theres a perception that the ARM Altra per-thread performance is really bad. But according to my Minecraft benchmarks in Oracle's instances, its better than old Skylake cloud instances... by how much is hard to say since other tenants generate so much variation, but there are proper reviews of the whole SoC floating around out there.

I've done a bit of minecraft benchmarking on my Oracle instance. It generates the same number of chunks per second as my 3600x CPU - although minecraft is always a weird benchmark in that benefits from low memory latency and large caches as it is ineffective at using caches well but is memory bound.

I’m currently setting up infrastructure for a startup and it’s been very interesting how the threat model of data loss and disaster recovery is no longer hardware failure: it’s account lock out.

I’ve got streaming replication of my core data going from one cloud company to other company as that way if one has some antifraud system go rogue on me I still have access.

As somebody who used to spend a lot of time thinking about drives breaking it’s an interesting shift.

Old Skylake cloud instances is "really bad" in the current day compared to Rome/Milan/Genoa, Sapphire Rapids and Graviton 3 for example. We've moved on from lakes!

To be fair Ampere Altra is old now too. Kinda a contemporary with Ice Lake and the tail end of Skylake.

Hetzner offering them right now is curious. Maybe its a pipecleaner for the next Ampere gen?

Those aren't the prices I'm seeing when I try to create a new server. I'm getting:

    CAX11 - 3.95eur/m
    CAX21 - 7.19/m
    CAX31 - 14.39/m
    CAX41 - 28.79/m

1 ipv6 costs me 0.6/m

presumably that's prices with the appropriate-to-your-location VAT applied?

Is this something new? I (Norwegian) have been using Hetzner for 10+ years, and never had a problem, and never had to attest my identity. CurrentlyI have a four servers running there. The last one was set up approx. a year ago, IIRC.

I don't understand the hype around ARM64 in the server space. Is this just due to all the marketing from Apple around their proprietary M processors leaking into the enterprise market? The latest Xeon and EPYC offerings are very performance competitive, I doubt we need to overhaul and entire processor ISA paradigm for continued improvements.

For me at least, if I knew I was getting same performance for less energy I’d actually be willing to pay a bit more. Data centers are big polluters still. I think we likely can get to nearly 100% renewables in the non-distant future, and lower energy per compute unit is part of that.

Could somebody walk me through why ARM based servers are so inexpensive compared to their x86 counterparts? Is performance much lower? 16 cores & 32gb of RAM for less than 25 euros seems like a bargain.

Power delivery and cooling are not cheap at datacenter levels.

With the added environment benefits!

That may be the difference. Some nationalities get KYC'd easier than others and they seem to take it very seriously

Looks like the ARM one has twice the memory bandwidth, which would help with a lot of workloads.

It's more along the lines of having roughly the same total bandwidth but being able to exploit all of it from a single core, whereas on Intel you need to exercise all or at least several cores to drive the memory to the limits.
