Re: I stumbled upon this article on the new Nvidia RTX GPUs

Hmmm, the things changed a bit with the v26.3 engine and CUDA backend. The previous graph in the thread was for v26 engine and OpenCL backend. The new CUDA backend (it's the fastest one with RTX GPUs) shows the largest improvement with RTX 2xxx GPUs and smaller with RTX 3xxx. So that I saw a benchm...

Re: Unfair Poll

Hmm, I tried some month ago to discuss in CTF what the limits of CTF shall be, and I had the pretty clear impression that people are strong free speech advocates in there, the "liberal front", I get this point, CTF would make no sense if a left-wing or right-wing takes over, the world in general is ...

Re: Stockfish bench in i486 & Pentium 75mhz !

Hehe, the SupraDrive hard-disk with 10 MB for 800,- Deutsch Mark appeared around 1986, not sure what the 20 MB version was, there you go with NNUE on 6502 :) https://www.atarimagazines.com/v5n6/Supradrivefor8Bit.html Apparently the C64 could also be connected to a HDD: https://en.wikipedia.org/wiki...

Re: Stockfish bench in i486 & Pentium 75mhz !

SF-NNUE depth 1 which is 500-1000 nodes is 2400Elo. That is at least 500 Elo above the best dedicated chess computers. SF-NNUE on 6502 would have for sure more than 1000nodes per move. It wouldn't be any contest, it would be a slaughter. and how is that supposed to work? the 6502 has a 16-bit addre...

Re: Dangerous turn

... [Option 2] Everything is up in the air. If you can provide an engine which has a large unique component, then it can compete. ... I guess this is what TCEC is up to, afaik TCEC is per invitation only, so they have already their own bias of what is unique and what not, further they listen to the...

Re: Dangerous turn

Hmm, how many Mega-Watt-hours went into the datasets of CCRL, chessdbcn, Lc0, etc.? How to catch up as independent developer without a CPU/GPU cluster? Fair competition vs. originality? Only the big players are able to pay the price for originality? Opening/sharing the datasets for free use and set ...

Re: CCRL flawed testing : SF12 above SF12 8CPU

One thing should be clear: there is nothing flawed in CCRL testing. They just play games, and record the results. What could be flawed is the Elo model used to analyze the testing data. This cannot be blamed on CCRL. It just means we have to develop better rating models, and use these instead to ex...

Re: Final Release of Ethereal, V12.75

It's not "a new evaluation term". A new evalution term doesn't discard the rest of the eval, it doesn't kill eval originality. It's a drop-in eval replacement. What is "eval originality"? Is there some term that chess engine programmers know about but nobody else does? I guess that every single eva...

Re: Which of the many chess engines in this forum use b strategy ?

... We are at a crossroads where we are no longer teaching the engines how to play chess. In fact, they know much better that we do. It is time to start asking them questions so that we can understand what it is that we are missing. Sure, unsubstantiated. Pure rumor and speculation. Perhaps pure, l...

Re: Final Release of Ethereal, V12.75

...everybody needs now and then a break from chess programming, some people come back some do not, leave your door ajar, maybe it will be interesting again in some time, or alike.
