Does CPU selection is enough for FreeBSD wordlbuild in 70 minutes + other tasks?

I am going to hardware shopping for a FreeBSD based computer, which should preferably comply with the following requirements:
1. Run a Blender/DaVinci Resolve render at 1080p at one VM, which would be backed by GPU.
2. At the same time of running FreeBSD worldbuild, compiling the entire system, in about 70 minutes at most, but not more than 50min when run alone.
3. Meanwhile I am doing some relative weak GPU task in another VM at the levels of doing realtime editing in DaVinci Resolve in a relatively complex 3D scene of Fusion, which would also backed by a GPU.
4. The ability of doing heavy math workloads like a SAT solver or a Computer Algebra System, this time there is not simultaneous requirement.
5. It has to have MMU and IO/MMU
6. Other not as CPU dependent requirements.
7. Preferably under $1000 USD.

I have considered the following CPUs:
1. Intel Xenon E5-2637 V4
2. Intel Xenon E5-2699 V3
3. AMD Ryzen 9 7950X
4. AMD Ryzen 7 7700

The Xenon CPU are the most attractive, as they come in relatively cheap used workstations, meanwhile the other two would likely be more expensive as I would have to buy all the components, and not just a new graphics board and a new hard drive.

My question is do all of this CPU selections does is enough to the required tasks?
Suggestions and comments are welcome.

All the cores in the world won't help a slow disk sub-system.

Cores+multiNVMe=speedy compiling

Xeon is good bet. v4 lga2011 is what I bought. 2695v4,2698v4 and a bunch of 2648/2650LV4
They are getting old though works fine.

I don't know if that is possible in Bhyve. Graphics card passthrough is still being worked on.
Plus you take a big speed hit running anything in a VM. Pass through a whole NVMe to VM is fastest route. Still speed hit.

I dont think any of this works on FreeBSD. Consult your manual.

Seriously though you don't even mention a GPU brand which is needed to evaluate your question.
NVidia passthrough works some. Will you get all the NVidia goodies that Linus has. No. Cuda.
Linuxuator gives you some features though.

Back on topic I would say yes. Provided a descent disk subsytem they should all compile world in under 70 min.
With nice swift NVMe AIC less.
If you monitor gstat and top you will see compiling is heavy on cores but when it needs to write it's a burst. It needs IO. Now.

Sub Rant.
2699v3 or v4 is max daddy. But look at TDP. Extra 15W and benchmark isn't that much better. Barn burner
Scale it back one click.
2695,2696,2697A,2698 prefer v4 too. These are getting old. Released 8 years ago.
Granted all these need cooling attention. Way above 100W per CPU.

E5-2637 is one I have never owned. Lower range. 2670 is not super hot yet still good benchmarks.

My philosophy is go big with 269x v4 or go Low Power with 2650L v4.
Many speak ill of 'L' chips but I like things that are cool running. I turn off many of my servers when not in use.
BMC makes that easy.
 
If you drill down on the Low Power chip E5-2650L v4 you will see it has a TDP of 65W but benchmarks at half of the speed of 269x line.
So half the power for half the performance. 14/28 cores for 65W versus 20/40 cores at 135W
Not suited for all use cases?
 
Not useless in dual CPU setup. Eighty lanes of PCIe bus for 130W.
Matter of opinion and use case.
I have some 11 slot SuperMicro rigs and I have them both ways. Low Power and High End.

Dynamics have changed some with PCIe 4x and PCIe 5x. readily available. For lanes and cores per dollar I like Low power CPU.

I am also undeclocker type. Never used liquid cooling on electronics in my life.

This is a CPU question, I may or not buy an NVIDIA and use the hacked drivers to get SR-IOV, or I may buy two graphical cards. Or do any other kind, I just want a CPU which, given an appropriate graphics card, can do the job.

And Linux has CUDA, you only need to use the proprietary drivers.

The workstation uses only SATA drives, and I am not considering very seriously the use of NVMe drives for my machine, as I think that prefer storage over speed, and at least in the Workstation selection, there is not NVMe slots.

For the other side with the at least 128GB of RAM that I plan to have it would be possible to do the word build in RAM, as a way to comply with the requirement?

Well the Xenon options are the things that come with used workstations in the second hand market. Thus I don't exactly have much choice of what CPU comes with.

I know that the workstation with the Intel Xenon E5-2699 V3 can have any of the following:
Intel Xeon E5-1680 v3 3.2 2133 8C CPU
Intel Xeon E5-1660 v3 3.0 2133 8C CPU
Intel Xeon E5-1650 v3 3.5 2133 6C CPU
Intel Xeon E5-1630 v3 3.7 2133 4C CPU
Intel Xeon E5-1620 v3 3.5 2133 4C CPU
Intel Xeon E5-1607 v3 3.1 1866 4C CPU
Intel Xeon E5-1603 v3 2.8 1866 4C CPU
Intel Xeon E5-2630 v3 2.4 1866 8C CPU
Intel Xeon E5-2637 v4 3.5 2400 4C CPU
Intel Xeon E5-2623 v4 2.6 2133 4C CPU
Because I found the manual: https://h30434.www3.hp.com/psg/atta...rkstation-POS/44923/2/Z440 QuickSpecs v36.pdf
Comes with more RAM than the other Xenon option, it as well as other considerations, I probably I am fine with the extra 15W for not as much performance.

Just how much is the idle power?

Also the Xenon cooling is not a problem as the workstations have already figured their manufacturer already accounted for the cooling.

Overall thanks.

I am not sure if the HP workstation is a dual CPU.
But thanks.
