Stockfish performing bad on ryzen cpu.

awsmak · Post by **awsmak** » Mon Sep 14, 2020 8:05 am

I have a new laptop with ryzen7 4800h 8core 16threads (zen2)processor. I was planning to use it to improve my chess and to find best moves. Previously i was using my smartphone with Snapdragon 855 processor for that. I am using stockfish 12 avx2 Binary on my laptop and using analyze this pro (sf12)application my smartphone. My laptop settings for stockfish are threads =8 and hash=512MB, all other settings are kept default even the network file. SF12 on my laptop give 9000+knps at opening whereas on my smartphone it is below 1600knps. I decided to compare the performance hoping that my laptop will easily win against my smartphone but interestingly it was my laptop always loosing or draw against my smartphone.i tried using stockfish 11 on both and now my smartphone always wins. I tried using different hashtable sizes and threads but still nothing changes. I also tried cfish,brainfish, sf12 development builds, bmi version and some other binaries that are made for zen2 based processors but there is no change in the results. Can anyone help me please.

Why your Droidfish is running < 1.6 mnps, are you using 1 core? 4 cores droidfish should be around 5 mnps.

Stockfish 11 gives 5000-6000knps stockfish 12 gives only 1500knps using 6 cores

I tried using Microsoft remote desktop app and also tried playing myself by copying each others moves. I have conducted atleast 200 games. I also tried playing against an i5 8300h processor on stockfish 12 bmi version which gets around 4000knps and it always wins against my smartphone. That is why I arrived at a conclusion that there is something wrong with stockfish on amd cpu.

There is a better way to do this, just use Chess for Android to setup and automate the task. There is a old app by Bernhard Wallner called netChess which will make this possible. I am even using it with Banksia and it works very well for in house (Windows to Windows) network games.

Here is an old post (2012) by Aart Bik Blog to get you started.

The only issue you may have to look out for is making sure that your Network Port is open in your Firewall / Router.

you tell nothing about time controls (how it is organized) and books (which engine where and when start to play on its own and what book it uses before)

I also have Analyze This pro, installed on my Samsung Galaxy S20 plus smartphone. I don't see stockfish 12 listed, only stockfish 11.
How did you install stockfish 12 on your android device?
