"Smolgen" Leela BT is new number 1 in the world ?

[Modern Times]

..... important to consider Leela BT as a potential world No. 1 in real tournament conditions, not rapid, bullet or blitz.

You call hundreds of cores, multiple GPUs and tens of thousands of dollars of hardware "real conditions" ?

Absolutely agree!
Frankly, one should go with the average CPU in evaluations....say 4 cores. Much beyond that is a vanity project.
At some point we have to agree that there are two things at play:
1. The engine and how it handles positions...1 core should be enough really.
2. The hardware...and that can always vary....scaling is a hardware thing.

Well, up to 16-core 32-thread Ryzens and similar Intel on single socket consumer motherboards are pretty common now, together with single gaming cards such as RTX 20,30 40 series etc. so apart from the very expensive and low volume RTX, that is pretty normal and real.

Some other hobbies are far more expensive than that

In TCEC tournament 2xA100-PCIE is used as GPU.
But what about if only one A100-PCIE is used. If only one GPU(A100) was used in the final, Stockfish would easily be the champion. If 4 GPU (A100) was used in the final, Lc0 would easily be the champion. It's not easy to compare Lc0 and Stockfish.
This is more of a match between Intel and Nvidia than a match between Stockfish and Lc0.

I think Lc0 is more advantageous for the future. Lc0 at RTX 4090 is ~%90 faster than Lc0 at RTX 3090.
Probably Lc0 at RTX 5090 would be ~%100 faster than Lc0 at RTX 4090. Progress on Intel processors are more slower according to Nvidia GPUs.
We shouldn't forget that the development in Stockfish in the last 1 year is ~10 elo at VLTC time control (~ 5 minutes/ 1 core). I think at tournament time conditions, the progress of Stockfish is no more than 4-5 elo.

looks like Leela is defeating Stockfish in the world championship .....

Stockfish is winning by 1 point now.

I'm eying an AMD 7950x....but lets face it, maybe less than 1% of desktop PC's currently in use are are the current generation AMD or even the current top Intel with about as many cores. So...no.

Yes I agree, GPU technology seems to be advancing more rapidly than CPU.

In Pohl list Leela is badly beaten by handicapped SF 15.1. So Leela needs 5000€ GPU.

I own both cards. BT2 is 2.1x faster on the 4090.

Has it chance against SF? Results please.

You could feed a family of 4 for a couple of years with what that card costs.
