They discuss a broad list of technical subjects -- regarding AMDs future CPUs and GPUs -- design philosophies, etc. Each was interesting. But, this article is not for everyone and no secrets or future product specifications are revealed.
What I liked was this one: AMD does NOT follow a Tick-Tock approach with products or a rigid "generation" followed by "generation plus" approach. Rather, they have multiple design teams that "leapfrog" each other. The result is that each product is designed to be the best AMD can provide at the time of release. If a "plus" makes sense, they do it. If an all new design makes sense, they do it. Moreover, the designs take "everything" into account (whatever "everything" might mean in a particular case).
