No mentions of AMD Ryzen?

I am just looking to crunch

Hi Bobby,
I operate as well two 10 year old Phenom II x6 machines, I initially planned to replace last year for a better performance/energy ratio.
The pandemics came in the middle of my plan and I had to postpone, in particular because of poor component availability here in Europe.

@chimmey17: I follow this thread since you started it. I would definitively avoid to choose a server, excepted if you have electricity power for free.
Even if servers are powerful, they are really noisy (loud) and drain a lot of electricity. Even if you can buy a used/refurbished server, and you have the feeling that it is "cheaper", the power consumption will severely impact your operational costs.

On my side, as soon as Ryzen 9 5900 will be really available in Europe, I will build new machines based on it. Epyc systems would be fun but they are definitively out of my budget.
Many years ago, I did operate an Intel workstation (Intel MB) based on a dual Xeon. The system experienced the shorter life of all my systems. It died after about 3.5 years (mainboard failure). Finally, even if the machine did good it did not justified the higher costs.
The Ryzen 9 5900/5950 already contents many cores (12 resp. 16) as well as large level 3 memory and they can operate many threads (24 resp. 32). Such systems will perform at least as good as older Xeon servers for significantly less electricity consumption and less noise.
Dual (or more) CPU configurations look attractive on paper, however, I am not really convinced that it will do better than the newer Ryzen CPU (Ryzen 9).
On my side, I already operate two Ryzen 7 2700 (65 W TDP) since nearly 2 years and they do a very good job.
Cheers,
Yves

By the way: I do not have any conflict of interest regarding AMD.

Sorry for the late response. At the minute I am not paying for my own power so that is not a problem for me but it is something that I will keep in mind. For using the rzyen posscer I believe that it would not work for me that well. this is because it is around 500 dollars just for CPU and then I would have to add everything else in whereas the xeons are around a 100 bucks each. then with the xeons would I not get better performance because it has a less of a clock speed but double the cores and threads are am I miss reading that as there is two core counts is that two different models. two last questios one will gpu make cpu worthless? and with the ryzen 7 I feel like I run into the same price problem and for sure the xeons would out run it due to way more cores and threads and the rzyen 7 only has a .7 gzh clock speed over the xeons .but it comes down to power overall do you think that due to having cheap power that I should go with the xeons or go with a more power-friendly modern CPU.

thanks for the reply

Applaud your intentions! I started with a couple of PCs, added some very cheap workstations and a rack, then some Intel servers, then a dedicated server room...it can get away from you easily! Try a single used Gen8 or Gen9 server with fast RAM and 2x 12 or 14-core CPUs (e.g., Xeon E5-2680v2 or such). Used servers are relatively cheap (10¢ on the dollar oftentimes) and a single one won't create too much heat or draw too much power - or be too loud, depending on where it's located. Keep it well ventilated. To get it up and running you'll have to learn a bit about server differences from PCs; fascinating. I'm running Win10Pro and Win10Workstation but you could try a Linux distro (e.g., Ubuntu) for economy. Plenty of open-source options and community support. [With enough RAM, you could add virtual machines (VMs).] See how it goes; you can build from there. Good luck!!
