> Intel also makes low power SoCs for mobile devices, e.g. Atom.

Last time I heard that name was well over a decade ago for crappy "netbook" devices. Just looked it up, last Atom CPU was released in 2013 per Wikipedia [1]. They might still make them for embedded computing purposes with very long life cycles, but no idea at which volume.
