Re: The Last Survivor of AB engine, Stockfish! What position will Stockfish stand?

My guess it that an overclocked i9-9960X or an overclocked i9-9980X are the two strongest CPUs for chess engines.
Their nps rivals systems with many more cores while only having 32 threads.

Another contender would be an overclocked Threadripper 2 2990WX.

Re: The Last Survivor of AB engine, Stockfish! What position will Stockfish stand?

Anyone remember Zeta, the AB engine on a GPU. It has the same problem where more NPS does not equal superior performance if NPS is the result of more cores. (workers) As you can see beyond 128 workers its NPS keeps scaling, but its real strength (time to depth) stops scaling beyond 128 workers. It h...

Re: The Last Survivor of AB engine, Stockfish! What position will Stockfish stand?

During the match they use for AB engines a server with 90 threads (HT = on) CPUs clock frequency 2.7 GHz and for NN engines 4xRTX 2080 Ti and a server with 36 physical cores (HT = off). The main issues for AB engines the short TC (5 min + 2sec) and they no use opening book. It would be a wonder if ...

Re: stockfish 10 vs. Mephisto III S Glasgow

If we're doing strange fixed nodes testing, then why not put Leela vs Mephisto at 1000 nodes. Surely that will be close. (I predict Leela will score 100-0 in a hundred game match) Obviously if your node contains much more calculations your engine will be stronger at fixed node count. Instead it sho...

Re: stockfish 10 vs. Mephisto III S Glasgow

It does not ? It beated Stockfish. With a software from 1984, That’s 35 years old. If Mephisto III has no chess understanding when using 1-3 NPS on 8 bit cpu or 3-5 on 16 bit cpu, How did it get the championship title against stupid opponents that did 1500 or more NPS ? Factor 500 or 300 (depending...

Re: The Last Survivor of AB engine, Stockfish! What position will Stockfish stand?

All I see is Leela times 3. It's kinda sketchy that 3 basically the same engines are allowed like that. If you add Brainfish, ASMfish, Thothfish with exchanging turned up and Sugar then the top 4 would probably be populated by AB engines again, but really it's just Stockfish with a different flavour...

Re: stockfish 10 vs. Mephisto III S Glasgow

I don't think you understand the central facts in the theory of chess programming: If you measure the strength of Elos starting from 1000 nodes /move and then always doubles the nodes/move, then the playing strength of Stockfish after 20 doubles increases to about 3500 ELO while the playing strengt...
