They'd already done this kind of things with the 'premium' epyc7371, a 7351 (16c 2.4GHz beating Xeon Gold 6130 for my workloads...) pushed at 3.xGHz? 13-18% perf increase on my workloads. More expensive but if you need the low-latency / high ipc (but no AVX512, well...) these AMD processors are beasts. Still love the 7551 too, for the price... And those were only Zen cores... Can't imagine Zen2/Zen3.
