Pretty good. About the same I think as my 10th Gen 65w Intel i9 10900 from early 2020.

Maybe you can give recent Lc0 with new Metal backend a try and compare CPU (blas backend) vs. GPU (Metal backend) on M1 Max?

v0.29.0
New metal backend for apple systems. This is now the default backend for macOS builds.

Terminal:
cd /Users/me/lc0-master/
./build.sh

./lc0 benchmark doesn't work. Bug?

BanksiaGUI:
LC0 807655
Metal:
Total time (ms) : 350993
Nodes searched : 496721
Nodes/second : 1415

How to change to backend when using Apples Terminal?
I tried to change the backend to Blas with BanksiaGUI. That's possible.
But when I try to run the benchmark inside BanksiaGUI it always starts to run the Metal backend. Bug?

...Bug?

Idk, maybe ask in Lc0 Discord or open an issue on GitHub?

***edit***
benchmark issue was already reported:
https://github.com/LeelaChessZero/lc0/issues/1795

I used the latest v0.29.0.
./lc0 benchmark doesn't work anymore.

***edit***
for testing CPU, maybe you can compile with Metal backend disabled:

Code: Select all

-Dmetal=disabled
