In case there is still confusion, these are embedded chips are low-TDP (17-35w) intended for things like NAS controllers the require x86, or other systems that require a reasonable amount of compute power.
But after reading the TPU source, I don't quite understand what other embedded applications would demand or benefit from a discrete video card. The first thing that occurs to me is something like a video game or slot machine. But they don't really enumerate specifics.
I'm not a big fan, but digital billboards and store signage seems to be quite a burgeoning market ...
