Can it be compatible? I have tested every npu accelerator

I re-built the app with the latest NPU interface libraries from Qualcomm (from Nov 1). According to the release notes these should support SD 8 gen 3. Due to lack of an 8 gen 3 device I can't test this, so please try it and report the result (new build is here: https://github.com/aki65/aki65.github.io/releases/tag/v1.19.2).

If it works, performance would be interesting, so please check the visits per second in the position from test.sgf.txt and check if ticking "parallel evaluation" makes any difference.

The speed I tested on my 8Gen2 phone is 400v/s, and the speed on 8Gen3 phone is 460v/s. There is no significant change in speed after parallel evaluation is turned on.

When running on these two mobile phones, both consume a lot of power and generate serious heat.

Thank you very much for testing. If "parallel evaluation" yields no improvement, it's best to keep it off and use only 2 search threads. If you haven't done so already, please try that setting (on my test devices it showed significant improvement).

Concerning battery drain and device temperature the latest version might be interesting for you: https://github.com/aki65/aki65.github.io/releases/tag/v1.19.3

It works well, thank you!
