These unfair practices by OEMs and Intel serve to exacerbate that problem and will make it harder for AMD to gather greater marketshare as well as mindshare which they could have otherwise reaped when supplies are greater. It's a double-whammy misfortune for AMD in that case, which they don't need as their tech really is advancing past Intel in many ways.
The issue at hand is that other, bigger OEMs are not putting AMD hardware into their best designs and thus yielding less than stellar performance or features. There are still cases of high-end Ryzen mobile CPUs being put into single-channel configurations!
I'd like to get a top tier AMD ultra portable for sure (eg. a Surface Pro) but AMD seems completely owhervelmed by demand in all areas and they prioirtise laptops the lowest (from their own release timelines and previous statements)
However, there is no denying that AMD is having supply issues and is arguably mismanaging the supply they do have with their constant paper launches.
