Re: What engine breaks even with GMs in blitz?

In blitz (let's say 3' + 2" or as close to this as possible), the top engines today are far beyond human level. But how far down the list do we have to go to find engines (and specified hardware) that score evenly against GMs, preferably ones with known identities and ratings? I'm sure there is ple...

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

It is even worst then this. This is such a lopsided tournament in favor of the NN engines. I looked up the benchmark for the $6000 Intel Xeon Platinum 8168. And what a piece of dog crap for 6 grand. And they bought 2 pieces of dog crap. Below is my benchmark for my $800 2950x. For a extra $5000 you...

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

It's easy to test really. From a random position SF10 reached depth 25 in 45 million nodes on 1 core. On 4 cores it reached depth 25 in 76.7 million nodes. While nps increased close to 4 fold (3.8 times as many). TTD only quicked 2.5 times. From 37 seconds to 15. A node is not a node when comparing ...

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...
