It's very possible; we'll have to see how the 5800X3D does. One thing that the M1 has that the competition doesn't is just more cache closer to the CPU.
The M1 Ultra, if it holds that it's just two Maxes glued together, has 48MB of L2 cache.[1]
AMD's newer 96MB VCache system in the 5800X3D is still L3 cache, with only 4MB of L2 cache.[2]
But that's a top of the line not-quite-released processor. AMD's current high-end (5950X) only has 8MB of L2 and 64MB of L3.[3] Meanwhile Intel's 12900HK only has 24MB of their Smart Cache[4], and the 12700K has 25 but with 12MB marked for L2[5].
It's not clear to me that cache is the be all and end all but it does seem to be a significant factor, especially if AMD's claims around the boost 96MB of L3 cache is going to give it are anything remotely correct.
