Not too many companies have a market cap over a trillion dollars, and if you don't then you can forget about competing on the upcoming process nodes that will require enormous capital.
Samsung's internal processor division seems to be sucking. Google is trying it half-heartedly like they do with nearly everything. Nvidia and AMD haven't really tried to compete for the desktop ARM market, and Intel certainly hasn't. Qualcomm has rolled their mobile chips for laptops, but they remain mobile chips in a larger form factor. So Apple is in a class of its own for desktop-grade ARM CPUs.
