As engines have been getting more and more optimized at playing chess, I was wondering if we've reached a point where no matter the hardware, most games still will end up as draws.
It would be great if anyone with a very powerful PC (16 cores or more) could test this with the most recent version of Stockfish: 1CPU vs 16CPU (or more) to see if there's an actual ELO difference between the two.
Is hardware still relevant in ELO gain?

Re: Is hardware still relevant in ELO gain?
If you use normal book then hardware does not change much at long time control and I remember tests that showed that result between engines are almost always draw even when one side has more than 10:1 time advantage.Juan P.

This is the reason that people use biased books in competitions like TCEC when they give engines positions that white has advantage that it is not clear if enough to win and in these cases there is still a big difference from faster hardware.

16 cores is not very powerful anymore. In TCEC Stockfish plays with 500 threads. And it is sure better than previous 100 threads engine. But is this enough to win with neutral book? At least you need very much games to detect possible minor gain..

Re: Is hardware still relevant in ELO gain?
Since you seem to know about the current match going on at TCEC - can you please enlighten me as to what the bonus event is all about? There was already a match between Stockfish and LC0 that just completed before this bonus match. Why have a bonus match? What is the point/purpose of such a bonus match?
Thanks for your help in understanding this.

Re: Is hardware still relevant in ELO gain?
This bonus will be a replay of the Superfinal
Same book
Same Time Control
Same engine versions
Same configurations (except obviously adjust hardware-related options: threads, minibatch size, hash)
Ponder on
Stockfish hardware: CPU: 2x AMD EPYC 9754. RAM: 24x 32GB DDR5
LCZero hardware: CPU: 2x AMD EPYC 9274F. GPU: 8x NVIDIA RTX 4090. RAM: 24x 32GB DDR5
Administered by Windfishballad.
So that makes an order of magnitude or 6x to 8x more nodes for Leela, 10x to 12x more for SF.
Highest quality chess match ever played!
