As another datapoint Ian (of Anandtech) estimated that the M1 would need to be clocked at 3.25Ghz to match Zen 3, and these systems are showing a 3.2Ghz clock: https://twitter.com/IanCutress/status/1326516048309460992

Up to 5050MHz is stock behavior for the 5950X and it's using standard DDR4 3200 memory.
Rather i suspect that the main benefit that M1 has in many real world benchmarks is that it has on-chip memory, cache-miss latency is a huge cost in the real world (why games has drifted towards DoD internals), so sidestepping that issue to a large extent by integrating memory on-die gives it a great boost.
I'm betting once they've reverse engineered the M1 perf, we will see multi-GB caches on AMD/Intel chips within 4 years.
