Requirements for the minimum amount of RAM for devices running Android depend on screen size and density and type of CPU, ranging from 816 MB– GB for 64-bit and 512 MB– GB for 32-bit meaning in practice 1 GB for the most common type of display (while minimum for Android watch is 416 MB).  The recommendation for Android is to have at least 512 MB of RAM,  while for "low RAM" devices 340 MB is the required minimum amount that does not include memory dedicated to various hardware components such as the baseband processor .  Android requires a 32-bit ARMv7 , MIPS or x86 architecture processor (latter two through unofficial ports),   together with an OpenGL ES compatible graphics processing unit (GPU).  Android supports OpenGL ES , , , and as of latest major version Vulkan . Some applications may explicitly require a certain version of the OpenGL ES, and suitable GPU hardware is required to run such applications.
