SF 11 vs T60 Lc0

[Nay Lin Tun]

This is what happens in chess.com bullet, when newly upgraded Stockfish 11 meet newly upgraded version of T60 lco ( Kiudee setting).

Note. T60 become officical version of Lc0 , T40 is a history now.

Hardware? Bullet is something like 1+1? SV 1541 old T40 size 256x20 is still the strongest up to Rapid TC (depending on hardware). Nevertheless, impressive 5-1 result.

Do you know if Lc0 engine (0.23.2) overcame 70-80k nps threshold in the opening and midgame? Also, the strength scaling from 2 GPUs to 4 GPUs has improved? It seemed bad to me until months ago.

Typical speeds in the openings are of the order 100M nps for Stockfish and some 50k nps for T60 larger net?

kai an equivalent amd ryzen to rtx 2080? 12,16,32 cores? (to be the same level with lco with 2080ti)

I haven't used Lc0 on CPU since 2018, but I think there is no way you get a CPU BLAS speed the level of CUDA 2080 Ti. Maybe something like 128 or more cores NPS-wise, don't know strength-wise.

Unless my setting is somehow broken. My ryzen in not even on the same planet as my 2080ti. And strength wise also makes no sense. But it would be cool, if that is true.

Probably in the range 16-32 cores, with the best SV or LS nets and new Lc0 parameters.

16 core ryzen +sf vs1 rtx 2080ti +Lc0 is my testing setup. And right now they are = in testing.
