Re: LCZero Chess Engine Performance ........

Thank you so much for this! This really gives a better idea of what kind of hardware to get the most cost effective performance. One question I have is how scaling affects all this. For example how does 2 x RTX 2060 Ti compare to a RTX Titan or RTX 2080Ti. This might also be helpful in choosing the...

Re: My non-OC RTX 2070 is very fast with Lc0

Thanks, I was expecting 1.5-1.6 faster, and it comes at little below 1.5 faster. Clearly not the best value. I hope, in some 6-9 months I will have a Ryzen 8 or 16 core machine with 2 x RTX 2070. I am not sure about the effective speed-up from 2 GPUs, it can be anything from 1.4 to 1.95. Nobody see...

Re: Alphazero news

Cerebelleum best book lines give even worse diversification to SF8 than SF8 itself on 44 threads. I have no confidence in that result. "Human Openings" given in A0 preprint (those 12) were heavily favoring A0, and I have again no confidence in that result. I don't even know how many openings they c...

Re: My non-OC RTX 2070 is very fast with Lc0

It is possible the CPU is also a limiting factor. This is a Sandy Bridge generation i5-2500k, In a week I will test with a more powerful one and then share the results. Despite being Sandy Bridge these are still relatively fast 4 cores, no way 45k nps would be a bottleneck on 4 cores. You can check...

Re: Alphazero news

There are two possible reasons for why Lc0 would lose more against SF if SF has a book. 1) Like you said, Lc0 is more specialized and doesn't play a diverse set of openings as well. 2) The quality of book moves are just higher in general than what Lc0 can come up with at short time control. So why ...

Simple reason is that I expect the opening moves of LC0 to be improved at long time control
You can expect whatever you want, but there is zero factual evidence that supports your expectation in this particular case.

Re: LCzero network

Nets vary in speed, even among test30 nets there is quite a variarion. Strength is measured at same time control, not same number of nodes. Same time control could mean different number of nodes. Interesting. Do you know why? I guess most assume same-size NN = same speed. Different net, different p...

Well, I am rarely using my RTX 2070 at full load for other tasks as of now (some Go engines will have it to use soon).
Gee man, you have very powerful raytracing graphics card and you only play Lc0??? Play some games for god sake at like 4k. :D
