On my i7-5960X 4.5GHz even with partial 7-piece syzygy.

7-cpu = 30s before syzygy win score
8-cpu = 25s before syzygy win score.

I recommend use latest brainfish

https://zipproth.de/Brainfish/download/

[Vinvin]

And in 2022, with 1 core and No EGTB, Stockfish finds a winning score after 6 seconds !!!
