Another Stockfish Experiment

[Werewolf]

I plan to run a this match:

SF 15 on 8 cores V SF 15 1 core, with the 1 core version getting 8x more time. Ponder off.

Other than predicting the 1 core version will win, anyone want to predict the elo difference?

(Openings will probably be Noomen Short)

The question is what time control.

I am not sure if 1 core win and maybe we are going to see 100% draws.

Maybe 1 min + 1s and 8 min + 8s

I would go with +30 Elo for the 1CPU version with 8 times the clock.

First interesting question is of
SF 15 on 1 cores(8+8 time control) V SF 15 1 core(1+1 time control), opening by Noomen Short

Assuming you do not use some biased opening book I guess we are going to see mainly draws so I will not be surprised if you are going to get less than 30 elo even in this case.

Waiting for results. SF wiki has one test:

Playing 8 threads vs 1 thread at LTC (60+0.6, 8moves_v3.pgn):

Score of t8 vs seq: 476 - 3 - 521 [0.737] 1000
Elo difference: 178.6 +/- 14.0, LOS: 100.0 %, DrawRatio: 52.1 %

Playing 1 thread at 8xLTC (480+4.8) vs (60+0.6) (8moves_v3.pgn):

Score of seq8 vs seq: 561 - 5 - 434 [0.778] 1000
Elo difference: 217.9 +/- 15.8, LOS: 100.0 %, DrawRatio: 43.4 %

Note this is pre-NNUE .
