Lc0 0.20.2 w32930 GPU (3452+14

)Quote
Author: Gary Linscott and others Links: Homepage, Networks
Games played on a GTX 1050 GPU with a Leela ratio of 1.65 (after 120 seconds) to Stockfish 8 1CPU on the AMD Phenom II X6 1090T test machine. For Lc0 fans - On a ratings list, Lc0 is NOT disadvantaged by playing 4CPU opponents. The Elo ratings system looks solely at the Elo rating of the opponent and the performance against it. The number of cores the opponent uses is irrelevant. To illustrate the point, on 24th March 2019, this Lc0 version had played 1,600 games with an overall rating of 3451 Elo. Against the eight 1CPU opponents, its performance was 3446 Elo. Against the eight 4CPU opponents, its performance was 3455 Elo. Within the statistical margin of error, the performance against both sets is the same.
This is one of the 12 Leela Chess versions we tested: Compare them!
