Branch Prediction

AMD's Zen 6 core family extends Zen 5 with wider out-of-order structures and a reworked integer scheduler layout that echoes Zen 3 and Zen 4. The direction predictor, already the strongest measured in Zen 5, is carried forward and refined. Zen 6 and Zen 6c are no longer the same core at two densities but two distinct cores tuned for different operating points, signaling deeper microarchitectural specialization.
