Lc0 0.21.1 JH.T6.532 GTX1050 (3492+16
−16		)Quote
Author: Gary Linscott and others Links: Homepage, Networks
Games played on GTX 1050 GPUs with a Leela ratio of 1.65 (after 120 seconds) to Stockfish 8 1CPU on two test machines, an AMD FX8350 and an AMD Phenom II X6 1090T. 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 to achieve its rating is not relevant to the calculation.
This is one of the 18 Leela Chess versions we tested: Compare them!
