CPU Recommendation for VM Server (alien.top)

Hey all!

Hope you all are doing well, I’m looking to build out my current homelab which is two mini PCs that I salvaged from my employer (one was a Intel OPS PC and the other a lenovo M93 Micro) paired with a linksys router (I forget the model)

I was looking at 1st and 2nd gen Threadripper chips (specifically 1950x and 2950x) and wanted to know what you all recommend.

I want the pcie lanes so I can pick up another graphics card (in addition to my current 1060) and some nvme cards.

Older Xeon systems (v3, v4) give you oodles of cores, main memory channels, and PCIe lanes. Single-threaded performance isn't great, but for multi-threaded workloads they're great value for the money and power.

Compare those threadripper systems to R730, T7910, and T7810, with E5-2680 and E5-2690 processors, and see which makes sense to you and your use-case.

The prices don’t seem to be competitive with the Epyc chips mentioned above.

Still a nice mention as I come in contact with these every once in a while.

Regarding the pre built systems I didnt mention I’m tight on space. Max depth of my rack is 20 inches. I can increase the height of a custom system and thats the plan.

Hold up, I stand corrected. These prebuilts come with a nice amount of hardware alone.

Interesting, this is going to be a tough decision

Thanks! 🙏

Where do you get your information?

Thanks! 🙏

Quite welcome :-)

Where do you get your information?

A few places:

Intel ARK for full CPU specs
CPUBenchmark for estimating perf and perf/watt
eBay for figuring out modern prices -- E5-2660v3 can be had for about $15, E5-2698v4 for about $110
Also eBay for figuring out what servers are available for cheap with a particular socket interface
This very subreddit of course :-) y'all rock
