Thoughts: Used Dual AMD CPUs & Motherboards

[hernandito]

Years ago I went the used dual Xeon 2670 CPU and ATX SuperMicro motherboard way. From eBay. It was a thread that started here. It’s been and still is awesome. I believe these were pulled from old Facebook servers or something like that. I have a total of 16 cores / 32 threads. It was all very cheap where MB, CPUs and ram totaled like $500 ~ $600.
 

I was curious about AMD and found something that’s potentially similar. There are matched pairs of AMD Opteron 2.6Ghz 12 core CPUs for $17. Then there are motherboards for dual Opteron CPUs that are quite cheap as well. I have not researched enough nor am I an AMD expert to see if CPUs and MBs are compatible. This would be 24 cores.

 

Is this something similar and/or better than the used Xeon adventure? Or are these CPUs way inferior to the old Xeon E5 2670? My Xeon CPUs are probably well over 10 years old.

The AMD items:

CPUs

Motherboard

 

It sounds too good to be true… hoping to get some quick thoughts before I start diving down that rabbit hole.

 

thanks.

you would need a dual G34 board like this beauty

 

Afaik the CPUs do not provide SMT, So 24 physical cores = 24 threads. But with a 6366 HE (85W) you can get a 16 cores CPU for less than $40/50 so could build a decent 32 core system that also support PCI-E 2.

Personally I wouldn't waste my time with old Opteron CPUs, I been checking ebay the last few days myself I actually have a newer gaming desktop but only 6 cores and max ram is 64gb only running 32 but the price to do upgrades is crazy compared to jusr running some xeon's. This seem to be the budget way to go for me

@onadeathstar that's good value for money, and you get SMT which will give you 32 threads.
