Seems pretty incredible AMD sold the keys to the kingdom for 1/4th the x86 market for 300millionish.
I'm sure the shenanegans where they get pushed out of china are going to occur after a few years, just like they happened to tons of tech companies before them after they got raided for IP with joint partnerships...
They never had much penetration into China to begin with, maybe they consider it worth it to cut down Intel's influence.
Seems super dangerous if china starts exporting the chips however.
