Some wikipedia reading will help you to understand.
x86ARMHiMedia Q10/Q5 Pro is power by Hisilicon Hi3798M V200 witch is ARM Cortex-A53, but f/w is running on 32bit Android SDK.
Download ARM (32bit) Kodi version to run on HIMedia Q10/Q5 Pro.
So long short story like @spurs85 write ARMv7a(32bit) , ARMv8A(64bit), x86(32bit), x64(64bit).
Thank you for the answer, but I knew that downloading from playstore you have the correct version.
My question remained unanswered, I wanted to know what was the difference between the various versions.
Thank you
