"game streaming services" is a non-market, sorry. Maybe in an investor's checklist of "potentially interesting futuristic-sounding stuff", but nothing that compares to, say, having a chip in every Xbox One and PS4, and dominating game development mindshare for the next years.
Depends on the margin. Nvidia pulled out of gaming consoles due to the margin MS and Sony dictated. AMD was fine with fulfilling demand at almost any margin.
