Comparison of ARM Cortex‑A76, A77 and A78 Microarchitectures

The article surveys ARM’s Cortex‑A76 design—detailing its DSU, cache hierarchy, branch predictor, larger ROB and execution units—then contrasts the A77’s macro‑op cache, larger ROB and wider execution pipelines, and the A78’s 5 nm‑based performance‑power gains, enhanced branch prediction, added MUL unit and expanded store bandwidth.
