AMD's 64-core, 128-thread processor for workstation/"prosumer"/enthusiast users has been reviewed:

In summary, it's fast and power efficient. Many applications won't benefit from more than 32 cores, and different versions of Windows 10 handle 128 threads differently.

Linus Torvalds Just Made A Big Optimization To Help Code Compilation Times On Big CPUs

For those using GNU Make in particular as their build system, the parallel build times are about to be a lot faster beginning with Linux 5.6 for large core count systems. This landing just after the AMD Threadripper 3990X 64-core / 128-thread CPU launch is one example of systems to benefit from this kernel change when compiling a lot of code and making use of many GNU Make jobs.

Linus Torvalds himself changed around the kernel's pipe code to use exclusive waits when reading or writing. While this doesn't mean much for traditional/common piping of data, the GNU Make job-server is a big benefactor as it relies upon a pipe for limiting the parallelism. This technique though employed by the GNU Make job server is inefficient with today's high core count CPUs as all of the spawned processes are woken up rather than a single reader to be woken upon a writer's release.

    Just make sure you get UDIMM ECC not RDIMM or LRDIMM since only EPYC supports those. Ryzen, especially Threadripper loves memory bandwidth so get 3200MHz modules.
