Depending on the benchmark the M1 wins at per core vs the Zen3. The threadripper is substantially behind at per core performance with the Zen2. The apple also has twice as many memory channels (8 vs 4) and runs the memory significantly faster (4266 vs 3200). The m1 also has about half the latency to main memory. So for highly random workloads that aren't cache friendly I'd expect the M1 to win.
