SPCC: Testrun of Fat Fritz 2 github finished

Post by pohl4711 » Tue Feb 16, 2021 8:29 am

AB-testrun of SF Fat Fritz 2 github finished.
Vondele (Stockfish team) made an avx2-compile of Fat Fritz 2 source code from github for me. I downloaded the free version of the FF2-net from GitHub. This is the freeware/GitHub version of Fat Fritz 2. Same conditions as in my testrun of Fat Fritz 2 commercial version. On my machine, Vondeles avx2-binary is around -7% slower, than the commercial FF2 avx2 binary. But that is no big deal, means an Elo-loss of (around) 3-4 Elo with my testing-conditions.

Fat Fritz 2 github has a suprisingly strong result in my testrun, compared to Fat Fritz 2 commercial. Of course, the github-version is weaker, but the difference is smaller as I expected.

Hi!
Can you please share the Github GPL 3.0 Fat Fritz 2.0 NOT COMMERCIAL Vondele version?
So more tests can be done by indipendent chess players :wink:

Thank you!

It is an avx2-binary. It works properly only with AMD Ryzen oder Threadripper CPUs.
