AMD reported $4.3 billion in Q3 2021 revenue, up 54% from a year earlier. Its data-center sales more than doubled. That’s a better sign than the share price on earnings night: customers were buying the products, not just the turnaround story.

I had watched AMD go from roughly $14 to around $120 over five years. That run wasn’t only about Intel stumbling. AMD had to ship competitive chips and win real server orders. I would watch whether the data-center growth held up before treating one strong quarter as a permanent lead.
