The AMD Ryzen Threadripper 3960X and 3970X Review: 24 and 32 Cores on 7nm
Today's launch covers two products: the 24-core TR 3960X and the 32-core TR 3970X. Both of these processors are built from four Zen 2 chiplets paired with a single I/O die, with each chiplet having 6 cores or 8 cores respectively. Both CPUs support 64 PCIe 4.0 lanes, four DDR4-3200 memory channels, and are built on a new sTRX4 socket with a new all-AMD TRX40 chipset.
[...] I have never used the word 'bloodbath' in a review before. It seems messy, violent, and a little bit gruesome. But when we look at the results from the new AMD Threadripper processors, it seems more than appropriate.
[...] AMD has scored wins across almost all of our benchmark suite. In anything embarrassingly parallel it rules the roost by a large margin (except for our one AVX-512 benchmark). Single threaded performance trails the high-frequency mainstream parts, but it is still very close. Even in memory sensitive workloads, an issue for the previous generation Threadripper parts, the new chiplet design has pushed performance to the next level. These new Threadripper processors win on core count, on high IPC, on high frequency, and on fast memory.
AMD Pre-Announces 64-core Threadripper 3990X: Time To Open Your Wallet
Ever since AMD announced its latest enterprise platform, Rome, and the EPYC 7002 series, one question that high-end desktop users have been wondering is when the 64-core hardware will filter down into more mainstream markets. White today AMD is announcing their Threadripper 3000 platform with 24-core and 32-core processors, the other part of AMD's announcement today is that yes, they will be selling 64-core hardware to the masses, in the form of the Threadripper 3990X.
AMD isn't giving too many details away just yet. As we predicted, there was room at the top of AMD's naming strategy to expose more Threadripper hardware: one does not simply stop as the 3970X being the most powerful processor, and the 3990X will certainly take the mantle. AMD is announcing today that the 3990X will have 64 cores, 128 threads, and will have the full 256 MB of L3 cache.

You are not going to be able to take advantage of 64c/128t with less than 2gb per thread. And once you have so much, you are going to want it to be ecc. Does threadripper 3k support ecc memory? What about the motherboard? AMD is just so ahead of the curve here I hope there aren't annoying problems that pop up.

64 cores should be enough for anybody.

That depends on the code you can run. With lockless data structures, it is possible and often quite useful to have many threads running effectively in the same address space.

Also re your current signature; Yeriḥo. Karthāgō. Sogdiana. Besièrs. 広島市 (Hiroshima-shi). For Love of God, what next?
There's no need to give Hiroshima twice. You can add the -shi if you think that's correct, but you're writing all the others in the latin script, with a few extensions a la ipa, unless you're deliberately trying to mark the last as super-duper special?
We don't even know what happened at Jericho. It was one of the earliest population centres in the world, one of the earliest areas to convert grass to cereal, but it also appears to have been depopulated multiple times, either simply by climate change or otherwise. The walled city described in the bible could be a memory of a time several centuries before Moses, but they cannot be historically accurate.
Nor should expect them to be. How many hints do you need?

Look out for a possible announcement of 8-channel memory versions in January.

Based on the second link, it drops to 1 DIMM per memory channel but adds support for the server memory types. So you have a chance of actually reaching 2 TB RAM, as long as you have the $$$.

I'm pretty sure it supports ECC. Even AMD's more desktop oriented CPUs have had "semi-official" and unofficial ECC support:
