New AMD Ryzen™ Threadripper™ PRO 3995WX (Windows and Multithreading Problem)

[syzygy]

Does asmFish give higher nps with 128 threads?

yes also Dragon by Komodo
only Stockfish has no increment from 64 to 128
and really incomprehensible to me

Ok, but the asmFish output you pasted here doesn't show its nps with 64 threads.

When you run Cfish from the command prompt, do you get output like this:

Code: Select all

info string Binding thread 0 to node 0 group 0.

Type this after you start cfish.exe:

Code: Select all

setoption name Threads value 128
go depth 10

This will only do a silly 10-ply search, but the point is that we want to check that you get the "info string Binding thread ..." lines.

[syzygy]

that's why I'm waiting for the Zen-3 Threadripper, when it arrives I will ditch the 3970X.

I'm afraid Zen-3 Threadripper will not happen.
(Hmm, apparently there are leaks about an August 2021 release date, but what are the chances that the chips will actually be available...)

[Alayan]

Zen 4 won't happen before 2022, so Zen 4 Threadripper would be mid-2022 or later likely. This is late enough that a Zen 3 Threadripper would make sense, even though late compared to mainstream CPUs. Availability might be a concern indeed, but a same socket upgrade keeping mobo and RAM as for Joost makes sense over waiting a year or two more for a good DDR5 threadripper.

Zen 4 threadrippers will be interesting. In CCC, we saw that correctly populating all RAM channels gave a significant nps boost to Stockfish, chess is a workload where big core machines are in part limited by memory.
