Re: Gentelmen, check your engines.
Just a single thread of a Ryzen 2700x I believe. Nothing too fancy. These endgame positions tend to have high NPS. I imagine Stockfish is in the same realm.amanjpro wrote: ↑Sun Sep 05, 2021 9:41 amWhat a speed... What is the CPU?AndrewGrant wrote: ↑Sun Sep 05, 2021 6:36 am Ethereal 13.35 NNUE

This speed (~3M NPS) is not very impressive if you ask me. However, Mergi's engine:amanjpro wrote: ↑Sun Sep 05, 2021 9:41 amWhat a speed... What is the CPU?AndrewGrant wrote: ↑Sun Sep 05, 2021 6:36 am Ethereal 13.35 NNUE

NPS is a silly metric. Can dick measure all day. Could probably get a 200mnps one if I really cared.

Re: Gentelmen, check your engines.
Yes, I'm sorry, I was cheating. It's run on i5 3350P, on 4 threads. Since the increase in NPS is pretty much linear, single threaded should be around 7m NPS on that processor. But i don't have NNUE nor do i do much of the fancy stuff that i'm sure Ethereal is doing.

Re: Gentelmen, check your engines.
It's still an impressive speed. NPS is certainly not a good metric for the quality/speed of an engine, but I guess it at least hints at the potential an engine has.Mergi wrote: ↑Sun Sep 05, 2021 12:17 pmYes, I'm sorry, I was cheating.

Re: Gentelmen, check your engines.
I'm not sure that is even true. Deep Blue got something like 400mnps if I recall some reading -- and still struggled to play super-GMs (where as now Stockfish can do it on everyday hardware). And Leela technically has very "low" NPS, although each Leela-Node is far more expensive, but also valuable and meaningful, than a Stockfish-Node or an Ethereal-node.R.

Yeah... one does not simply brute-force his way into mordor, I guess...AndrewGrant wrote: ↑Sun Sep 05, 2021 12:25 pm I'm not sure that is even true.
