Unfortunately the problem for us at Power is always the same, on the software side that you will have to use for your works, what optimization will you have ?!  We usually suffer on this front compared to X86 ...

Woof:
I'll be doing some comparison between the 3990X and my dual Power9 running our custom texture compression code. I'll not get around to it for a while though. The code scales quite well with more cores but eventually becomes memory bound. Our 3990X machines here are all overclocked and hand tuned, so I think it'll be a tough one to beat.

MPC7500:
POWER9 is already aged. It will easily be slaughtered by the Threadripper.
Ah, BTW you can overclock POWER9, too.
Maybe you could provide some benchmarks, if you're finished.

Woof:
I'll post real findings but I found the 3990X doesn't scale out linearly for our use. For our highly parallelised task (imagine 65'000 blocks of the same size being processed) going from 64 to 128 cores yields a 37% speed increase. I think we get hit by the four memory channels.

Overclocking the Power9 is on my list to look at (I'm assuming the power stages to be the limit here though). OC'ing the 3990X is a complete power hog, and we're able to draw over 800W for the CPU/mobo alone (for the TR Pros we have here with 4x RTX6000 we struggle to keep in the 2kW power limit of the PSU and wall socket).

MauryG5:
Woof do you like me use Ubuntu on Power? We are few who use it here, you too have found the Firefox problems I have been talking about for some time, such as the bug of the bookmark that does not work and the problem that occurs when you use Firefox on certain sites ...
