Hetzner Cloud - CPU optimized servers with AMD EPYC
Just noticed they added some new Cloud Servers to their lineup.
Did anyone test it yet?

just spin 1 server

Coud you please run Geekbench 4 please?

Rescaled one of my servers to use the EPYC CPU:s:
Awesome @Hetzner_OL
This is great! I might celebrate by cancelling a couple of Scaleway dedis that I have idling .
Loos promise!
What's the best single thread Geekbench4 score so far on these?
Geekbench score is a good 25-50% lower than I’d expect from what’s probably an EPYC 7502(P). But this may be because @Hetzner_OL doesn't pass through the full cpu?
Cpu contention already? I guess I'm not too surprised. But that geekbench score looked pretty good to me, given the relatively low ghz.
I’m definitely not saying it’s bad, especially for this kind of money.
But on a second gen EPYC you’d expect a single core score of around 4000-4700 and what I’m seeing in the Geekbench browser are scores between 2700-3200. I don’t know what causes this. Is it overbooking, noisy neighbors or just because the cpu core isn’t passed through?
Each "core" is actually a hardware thread (vcore), ~ 50% of a physical core. So if the box is fully utilized then even without noisy neighbors you're doing good with 60% of what you'd see on an empty machine. I tested a CX51 (8 Intel vcores, 32gb ram) a while back, doing a sustained calculation on all 8 vcores for about 3 hours, and was happy to find that I really seemed to get close to the performance of 8 physical cores. I wonder how the CPX51 (16 Epyc vcores, 32gb ram) will compare. I guess I shouldn't expect too much, since all competing products cost quite a lot more.
yah, I got all these gb4 numbers in my head
@debaser We also have Hetzner Cloud options with dedicated virtual CPUs. These plans (CCX line) are based on Intel Xeon Skylake processors.
A few other customers have asked about dedicated plans for EPYC based Cloud Servers (CPX line). If you would be interested in this, I can add a +1 to the customer wishlist for you. Helena pass these onto the dev team so they can consider what they can work on for the future. --Katie

I know about CCX but they are way more expensive than CX/CPX. I like the CPX idea. The main interest of dedicated cpu dedicated Epyc instances (CCPX?) would be very large ones, like with 1TB ram. I couldn't afford to use those myself, but having them available would extend Hetzner's range to be more competitive with the big providers like AWS, which do have them. As for CPX, I'll wait to see how the benchmarks play out and will run some of my own tests when I can, but having more vcores at increased contention levels (so without more real speed) doesn't seem like that great a proposition.
Meanwhile, there are some new Epyc CPU's (7F series) that run at higher ghz than the standard ones, at not that large a price premium (article. This is pretty cool. I'm sure your hardware team knows about them so I hope you'll use them at some point. I've foound Vultr's high frequency instances (similar idea with Intel cpus) to be quite impressive.
Anyway, congrats on the new product! As new variants get introduced I'm sure some will have the right balance even if the current ones turn out not to.
My YABS bench thread has one on falkenstein. Not as well performing as the one in Helsinki as shown above.
Overall decent, good iops with adequate storage.
I bench YABS 24/7/365 unless it's a leap year.
