If you like numbers, here are the benchmark results of an Intel Core i7-7700K@4.2GHz and a Nvidia GeForce GTX 1080.
Leela 0.10.0:
Code:
200000 games in 7.06 seconds -> 28328 g/s (3541 g/s per thread)
Avg Len: 451.75 Score: -1.973360
CPU:
2000 predictions in 21.45 seconds -> 93 p/s
10000 evaluations in 22.74 seconds -> 439 p/s
GPU:
2000 predictions in 1.69 seconds -> 1183 p/s
10000 evaluations in 3.92 seconds -> 2551 p/s
Leela 0.11.0b11:
Code:
200000 games in 8.39 seconds -> 23837 g/s (2979 g/s per thread)
Avg Len: 418.56 Score: -2.432680
CPU:
2000 predictions in 15.97 seconds -> 125 p/s
10000 evaluations in 33.16 seconds -> 301 p/s
GPU:
2000 predictions in 3.28 seconds -> 609 p/s
10000 evaluations in 4.13 seconds -> 2421 p/s
And I have some games of Leela 0.11.0b11 against CSDL with and without GPU, Leela 0.11.0b11 with GPU against itself without GPU and Leela 0.11.b12 against AQ 2.0.3.1. Leela’s opening book was used. Time limit was 30 minutes in all cases (CSDL had 30 minutes + 5s byoyomi, because setting absolute times is not possible, but it had never used the additional time).
I like Leela’s aggressive and exact style; the games against CSDL are interesting. By the way: Leela with GPU won all games except the last one against AQ. Leela was leading very clearly, made a questionable move which forced it to ignore the next Ko thread, but even than it would have won but instead surprisingly gave up.
