Re: Stockfish_dev is probably stronger than Sargon 1978 v1.00

I don't think the weak 6 ply searches matter at all. You can get to 15 plies in an eyeblink. If you like ultra-hyper-bullet game in one tenth of a second, then use Komodo. I am not sure how the NN programs would do at ludicrously short time control. It would be interesting to see an LC0/Komodo matc...

Re: Stockfish_dev is probably stronger than Sargon 1978 v1.00

I tried Sargon depth 8 vs SF.
But I got bored from waiting, those are some humongous time odds in favour of the ancient engine.

But thanks for linking it, it's an interesting engine.

Re: SPCC: Testrun of Komodo 14 finished

It seems impossible to catch Stockfish for Komodo now. The difference between Stockfish Dev and Komodo is a huge number like 131 elo. This situation will negatively affect the motivation of Komodo authors. Because the development of Houdini engine has stopped and Ethereal and Xiphos engines are far...

Re: Which is stronger AlphaZero( 5000 TPU) or Stockfish(30.000 Cores)

With Lazy SMP fixed depth is not a correct measure of strength. Probably the 8 threaded search is wider to the same depth compared to 4 threaded search, and probably stronger to the same depth. how to run test tournament? I use Arena 3.5, cannot find how to assign different Threads count for partic...

Leela is stronger than both.
Do you know how many graphics cards Lc0 can support? Is it 4?
I think 4 but I don't think it scales much (if at all) beyond 3.

Re: Which is stronger AlphaZero( 5000 TPU) or Stockfish(30.000 Cores)

Stockfish (4 core) has 3493 elo according to CCRL (40/15). Stockfish 11 dev has ~3500 elo. Stockfish speed is 4.800.000kn/s at 4096 cores. It's nearly 2000x of Stockfish at 4 cores. The speed of 2x Athlon 4600(main engine of CCRL then they changed the main engine but the elo of engines didn't chang...
