Well, Minecraft comes with a steady supply of money. AMD is currently a sink-hole for cash.
I’m just not sure what AMD can do to get back in the game. At least their GPUs are still almost at parity with Nvidia GPUs, although the elastic is starting to stretch. It’s snapped completely with its CPUs. If MS have a large pot of cash, great. Maybe something can be done.
However, I wouldn’t be surprised to learn that this is just a way to ensure the supply of AMD chips in its console, and perhaps cutting out Sony.
