Re: End of Era is there: SF is finally beaten!

Very true ... I think that SF even on 1000 cores would still lose to Lc0 some pretty spectacular games. I mean just look at yesterday's loss ... out of the opening and each engine plays a few moves by itself and you have this position [d]r2q1k1r/3b1pp1/1p2p2p/p2pP2P/P1p2P2/3B4/2P1QBP1/R3K2R w KQ - ...

Re: LC0 bad search and poor tactics

Looking at positional patterns, there are certain patterns that lend themselves to tactics. This is the whole reason human players practice tactical puzzles to recognize these patterns. Steering to them or away from them depending on which side you are playing, improves play. You make a positional ...

Re: Alphazero news

You're aware that this paper was submitted a year ago, right, long before the RTX series was announced? Google had no say the lead time here; that was up to the journal. Not true, the paper was submitted in March, RTX was announced in August, but unofficially it was very well known that 20xx genera...

Re: Upcoming graphics cards for Leela

Tensor core performance on RTX 8000 was explicitly mentioned during the new Quadro cards reveal. Going by memory it's 125 TFLOPs for fp16, :shock: Lc0 can't use Tensor yet though ? There are some benchmarks showing that lc0 is ~ 3x faster on Titan V than on 1080 Ti Huge part of it I am sure comes f...

Re: Upcoming graphics cards for Leela

For some reason Wikipedia doesn't list the FP16 performance of the Quadro cards. They definitely do half precision? https://en.wikipedia.org/wiki/List_of_Nvidia_graphics_processing_units#Quadro_Pxxx_series Nothing is sure before someone actually tests card for specific performance, but there are qu...

Re: CPU vs GPU...fair play...keep it simple

AMD Threadripper 1950x vs 1080Ti AMD Threadripper 1920x vs 1080 AMD Ryzen 7 1800x vs 1070 AMD Ryzen 7 1700 vs 1060 Soon nvidia line will get updated for RTX 20xx (which should cost about the same as 10xx cards today), so I am wondering how much better for example 2080Ti will be compared to 1080Ti. ...

Re: Strange Lc0 TCEC performance

Problem was even more serious for Leela as she had this aggressive pruning thing setting that made the situation worse. Yes, the TCEC chat is buzzing with details about the HW issue: seems there is part of the code that determines if current best move (with most visits) can be overtaken by some oth...

Re: LCZero: Progress and Scaling. Relation to CCRL Elo

I plan to play 200 games to get a rough idea of how strong the current engine + net is, I'll post the results here. I have to agree with Albert - after 100 games perf is -60 elo compared to ID 24x so fanboys can cry now, they should revert to 0.7 ASAP! Reverting to an earlier version just because s...
