OK, so I have this CPU version of LC0 v 0.16 (blas). How strong is it on a single CPU with the latest network (573)?
Maybe Fruit 2.1 level in CCRL 40/4 conditions. Haven't checked on CPU long time. Also, always specify TC.
Lc0 0.16 on 1060 (net 570) that gets 7200nps is around 29% vs. latest SFdev on single core on 40/4 TC. That is roughly 250Elo below SFdev.
Lc0 0.16 blas on single core is around 24nps. That is like 300x or like 8.3 doublings weaker than on 1060. If we assume a doubling is like 60 Elo (conservative) that is at least another 500Elo in addition to those 250Elo. Assuming latest SFdev on 40/4 single core is around 3520Elo, Lc0 0.16 single core is not stronger than 2750Elo, which is around Fruit 2.1.
Searching only 24nps and playing at 2750Elo is still impressive, I would say. I wonder what's the limit of Leela strength on single CPU. Is she capable of reaching 2900? 3000? More?

FIDE ELO does not define 0 = random play. That concept was not at stake when ELO was invented. Perhaps that could be changed nowadays, but I really doubt it will be.
