CPU preference AMD or Intel

Postby jonathankonrad » Sat Dec 07, 2013 9:05 pm

I am about to virtualize my HDA. I have not decided which hypervisor to use, but before I play with that I wanted to see if anyone had an opinion on which CPU. I have an Intel i5 4570. I could pick up an AMD 8320 for a good price. Obviously the AMD has more cores, which might help with my setup (3 - 4 VMs), but I owned an AMD 8120 a while back and I find the i5 4570 to be noticeably stronger in most computing tasks.

So i5 4570

or

AMD 8320

Has anyone had the chance to run both with a Hypervisor like Proxmox or ESXi? Performance? Pro/Cons? Thanks for any tips. I use my HDA as DNS, DCHP, Backup, iTunes streaming , Minecraft server, Proxy, video media streamer. Well, I actually run two other machines to act as a Minecraft server and an video streamer to iOS. I want to move those functions to my HDA when I rebuild it on a hypervisor..

Both can handle virtualization just fine, but for home consumer use, I would always go for whichever give you more cores with the least power consumption and then of course price.
It's really a per-user preference.

As for deciding on a hypervisor, get a look at the posts we have in the virtualization section of the forums, as well as our run-downs in the Amahi wiki. Then get a good read in the forums for each hypervisor to see what qualms have already come up with other users. Pro/Con lists have already been made all over the place. Find what you are comfortable with, or what you might end up wanting to learn for other benefit.

Thank you. I have been reading the other threads for Pro/Cons on the hypervisor to use. I will continue to go there for more advice. I was focused on AMD vs Intel for the Pro/Con list. However, I'm getting the feel that it may not matter too much as I will not have that many VMs running. I am going to start with the Intel i5, since that is what I have. If it does not run well, I'll look in to rebuilding on an 8 core rig after the boxing day specials! Thanks.

Does anyone know if I will have a problem later moving over my VMs if I start on an Intel processor and then later move the containers on to an AMD CPU?

Hmmm. this is about changing base level hardware with the HDA. I was wondering specifically about swapping underlying CPUs and it's affect on virtualized hardware. I believe some of the virtualization instruction sets are different with Intel or AMD, and I did not know if that affected the VMs that would be built on one platform then transferred to the other. I'll try to see what I can find on other forums for virtualization. Good link on changing real hardware though, and in reading it, it seems like the virtual HDA would simply detect the change as a hardware change and keep on ticking.

If you're using specific CPU features from a virtual CPU, yes then you will want to use the same CPU. In most cases, casual Amahi users with VMs needn't worry about CPU specifics. Fedora and Ubuntu play fine with nearly any CPU you give it
