Code Compilation, Web Server, Game Hosting... Epyc, Threadripper, or Consumer CPU?

unwind-protect
It is mainly puff piece for TR

a lot more than 8-12 core

can mean anything...
OP should have asked Epic what is the max scaling for UE4 compilation then proceed from there.

Yeah, but support can be "interesting" on such technical questions. There is a possibility of no useful answer except for "more cores are better".

I don't know how easy that is for Windows, but if I needed to determine max parallelism I would rent some 128 core machine from AWS for a couple hours and have a look myself. I think that's $12/hour, well worth it.

If I was on UE4 right now I would get a 7950x/x3d or 13900k with 128 GB and forget about the whole affair unless it actually turns out to fall short of the possible parallelism AND it is still too slow to be productive. There's also rumor that the next Zen/Ryzen generation has more cores, and it will use the same socket. So you might be able to upgrade.

I would agree with unwind; the 7950x at this moment is much better platform to be on.

7950x v TR zen2

7950x will run cooler, and eat less power
It will have much higher IPC (i'd say around 35-40% more in single core performance)
It has much better clocks
Its first in generation, at very least 1 improved gen Tok CPU will available in future for upgrade.
DDR5 gets you almost same memory throughput but with even less latency vs TR
The caches are split on TR zen2 platform anyway so cache performance wise will be almost the same (if you get the 3d you will be even further way ahead)

The only real short the 7950x platform has is the ram cap at 128GB. Newer cpu's in future may raise it.

Theoretically it can do 192 GB. But I am not aware of anybody who did that yet.

Realistically, the cap will probably increase to 256GB within a couple years. 64GB DDR5 consumer (UDIMM) modules aren't too far off
