First, many of these benchmarks are single threaded. Secondly, in the same power envelope as the 5800X you can also find the 16 core 5950X. So perhaps Apple would have to add even more cores. Finally, in a core count war AMD has an easier task. They scale up their designs with multiple chips. A Zen 3 CCD is about 80mm^2 on 7nm, which is already much smaller than the M1 SoC on 5nm. If Apple adds 4 more cores, their chip size will increase. Meanwhile AMD can add more cores without increasing chip size like Apple's current integrated approach. This is why AMD is already shipping 64 core CPUs (EPYC 7763) using multiple of the Zen 3 CCD as these desktop CPUs.
