UCI-engine under Snapdragon X Elite

Post by mpvank »

Hi there,

is it possible to use the Stockfish engine with CB17, using WIndows 11 on a new laptop with an ARM-processor (Snapdragon X Elite)?
I installed MS Prism but cannot see a way to use this program in CB17.

greetings,
Menno

Snapdragon X Elite X1E78100 3.42 GHz 32.0 GB RAM (ASUS Vivobook S 15) running the Stockfish 16.1 popcnt build from stockfish.org gets the following on the bench command. The Snapdragon cannot run the AVX2 or BMI2 build. It just exits with no message whatsoever.

Thank you.
And does this mean it is not possible to use the Stockfish uci-engine with a snapdragon processor?

It is possible but you have to use the popcnt build so it means it searches slower and is thus weaker than the avx2 build. You can download it here.
