Will AMD RDNA2 based Radeon RX 6000 series kick butt with Lc0?

AMD teased its RX 6000 series with new RDNA2 architecture (already in use in PlayStation/Xbox gamer consoles) and released as high-end consumer series on Nov 18th. Take a look at the FP16, half precision, performance, pretty! https://en.wikipedia.org/wiki/Radeon_RX_6000_series AFAIK RDNA2 supports R...

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: Graphics Card

What is the best graphics card to buy, of course, at a reasonable price for the engine LCZero. Thank you in advance for any advice and advice. IIRC Laskos wrote last year that Nvidia RTX 2070 offers the best price/performance sweet spot, then the RTX 20xx Super series were released, not sure about ...

Re: Hardware questions

3. Ryzen vs Threadripper I am somewhat confused as to the benefits of using a TR vs a Ryzen of the same generation, assuming an equal number of cores and similar frequencies. Is there an architectural difference that matters significantly for Stockfish? If yes, how much? The Ryzens have much lower ...

Transhuman Chess with NN and RL...

Heyho, some 2 cents on this... Some people argue that the art of writing a chess engine lies in the evaluation function. A programmer gets into the expert knowledge of the domain of chess and encodes this via evaluation terms in his engine. We had the division between chess advisor and chess program...

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

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...
