I found a new test suite called «Stockfish Test Suite 2021» (STS) in this German forum. The test is a compilation/extract of 20+ more or less well know test suites and contains 238 positions which were not solved by cfish on the author’s older computer. The epd-file is here: Stockfish-Test-Suite-2021
I run the test on my M1 with the fresh compiled Stockfish family binaries (see this page). Configuration: 5 seconds for each position, 1 thread, 1024 MB hash, tests executed with epdtest.
The results – or better: the differences – are quite astonishing, at least for me. Also published are the results of the ERET. You can download the log files for both tests here: log.zip
