Intel or AMD ?
-
Hi everyone,
I'm currently in the planning phase of setting up a new server environment using XCP-ng as the hypervisor, and I'm at a crossroads trying to decide between AMD and Intel processors. I understand that both have their strengths and it's quite challenging to make a clear-cut decision without some seasoned input.
From a performance standpoint, I know that AMD often offers more cores and threads which could be advantageous for highly parallel tasks. On the other hand, Intel has robust performance credentials and certain features that are particularly beneficial in virtualized environments.
Cost efficiency is also a factor I’m considering. I'm aware that AMD generally provides a better price-to-performance ratio, but there are other aspects like power consumption and overall TCO (Total Cost of Ownership) that need to be considered.
Furthermore, I am curious about compatibility and stability issues with XCP-ng. Are there any known issues with either AMD or Intel in terms of support for virtualization features, drivers, or overall system stability? I absolutely need reliability in this environment.
Lastly, are there specific models from AMD or Intel that you guys have had positive experiences with in terms of performance, stability, and compatibility in a virtualized setup?
I’d greatly appreciate any advice or experiences you can share regarding the use of AMD or Intel CPUs in a XCP-ng environment. This is a significant deployment for me, and I want to ensure I make an informed decision that I won’t regret down the line.
Thanks in advance for your help!

Hi,
It's hard to answer perfectly, because it also depends on the segment. But short answer personally: AMD.

@still_at_work Personally would say AMD, almost all XCP-ng servers I manage are AMD based and have been excellent so far. Usually a better value and better overall performance and their high core counts are great for virtualization unless you specifically need something that is faster single threaded.
I have 3 hosts in my lab, all Threadripper (so baby EPYC) and they've been rock solid as well.
