Lc0 or other GPU-Neural Nets versus Stockfish 15.1 testing
Playing conditions:
Hardware: Ryzen 7 6800H 2.6GHz Notebook, RTX 3060 GPU, Windows 11 64bit, 32GB RAM
Cuda version installed: Cuda 12.7
Speed: Stockfish 15.1 plays with 14 Threads (=7 cores) and reaches 10 MN/s in the middlegame. Lc0 minibatchsize parameter is set to the best value for each netsize, depending on Lc0's benchmark with backendbench --clippy.
Hash: 2 GB Hash for Stockfish 15.1 / (NNCacheSize 1000000 or 8192 RamLimitMb for Lc0)
GUI: Cutechess-cli (GUI ends game, when a 5-piece endgame is on the board)
Tablebases: None for engines, 5 Syzygy for cutechess-cli

Thinking time: 2min+2sec for Lc0 and 1min+1sec for Stockfish 15.1: I measured nps on my system and compared these values with the TCEC: My CPU is way too fast, compared with Lc0 running on my RTX 3060 GPU, so it makes sense to set the thinking-time of Stockfish to only 50% of the thinking-time of Lc0. For compensating the fast CPU and the fact, that in TCEC Lc0 benefits from fast hardware and long thinking-time (both is better for Lc0, not for Stockfish)
One testrun takes around nearly 5 days. Average game-duration: 6min 45sec
