It was fun seeing their materials refer to their branch predictor as a TAGE predictor. I remember hearing about the original paper for that when I was too young and inexperienced to focus long enough to understand it; then I saw a TAGE predictor show up in Chris Celio's BOOM repository, and I read it through. If what AMD says is true, the new (for them) TAGE predictor in their industry-leading microarchitecture having 30% fewer branch mispredictions than the last, it feels very cool that one can read and somewhat anderstand the operation of a similar predictor in the leisure hours of a few days. Also those caches are huge, wow.
