Great news. I'd like to see how a vCPU compares between arm64 and amd64 but not sure how to best go about it. I've created VMs for both with 4 vCPU and will run the phoronix benchmark suite. After that I'll probably try 16 arm vs 8 amd vCPU because that's a closer match in terms of price. Any suggestions welcome but I also don't want to spend too many hours on it. Will post results. Ran the kernel build benchmark (re…

The main problem I'd think is that by being "virtual" you never really quite know if you're seeing how it would run in "real life".

Personally, if I were to do it, and I had some sort of load-balanced application that uses multiple backends/frontends/whatever, is balance across the two and compare over time.

And to be 'fair' you'd want to compare similar pricing.

Or if you had a consistent group maybe try a Minecraft server and move it between the two every week and see what people "feel"?

That depends on how many vCPUs are they running on each physical core for both x86 and ARM.

Did a quick comparison between intel 2 vCPU and Arm 2 vCPU, these are shared CPUs though so YMMV: sysbench cpu --threads=2 run Intel events per second: 1864.20 Arm events per second: 6687.05 Coremark Intel iterations/sec: 20077.633516 Arm iterations/sec: 23625.767837

If you have access to them a much more informative datapoint would be `openssl speed rsa` or `lzbench`. Sysbench is just a stunt it doesn't indicate much at all.

Earlier quoted context omitted.

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!

Cooper Lake (2020) is still a Skylake. They aren't that old!

The 1 that was mostly canned?

See: https://www.anandtech.com/show/15631/intels-cooper-lake-plan...

It's limited everywhere.

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 benchmarked ARM systems vs other processors. On my workload, using Intel as a baseline. AMD under performs relative to standard benchmarks. ARM over performs relative to standard benchmarks. I have seen good performance from Ampere, particularly for the price. However, ARM architecture complicates my workflow significantly. I've found that they are not worth using it right now due to compatibility issues, easier…

Try alpinelinux, you'll be able to find almost everything, coupled with nix for just in case. I've yet to find any package missing.
