Stadia etc could still ruin it for AMD. You no longer need local power to game
And of course you still need that local client to play it, which might as well be an AMD-powered ultrabook. At which point Stadia just resulted in AMD selling up to 3 products instead of just 1 (GPU & CPU in the server + APU in the laptop)
Stadia is for the person who has 1hr every few days to play a game casually on the TV or 20 minutes during lunch.
It caters perfectly for the crowd of people who do not want to be locked to a specific device (gaming pc) or update their console/games.
The high static time cost of gaming in 2020 is what stadia mitigates.
And anyway. Stadia is powered by AMD underneath.
Probably good only for Google employees who are forced to use Chromebooks.
