Honestly, I do agree, it is kind of ridiculous that it is fighting neck and neck with relatively overclocked AMD and Intel CPUs. I always do a little bit of overclocking but some of these overclocks are pretty high.
Still, I do think some of Apple's inherent advantages make it less surprising that they're able to win on benchmarks. Again, the process node, the RAM directly on the chip. And hell, they are probably also able to get here because of targeting AArch64 with no 32-bit ARM compatibility.
Either way, Apple appears to be a couple years ahead of the competition right now when it comes to efficient processors, just like they were with the M1.
