There's nothing special about ARM, sure. Hence "for whatever reason". Still, ARM is a known quantity, and the leading alternative to x86 for desktop CPUs. The article is titled "reaching desktop performance".

We know how Apple's hardware performs on native workloads. We know how it performs emulating x86 workloads (and why). Surely "... and this is how this hardware measures up against the other guys trying to achieve the exact same thing" is a relevant comparison? I can't be the only person who reads "reaching desktop performance" and wonders "you mean comparable to the M1, or to the M3 Ultra?"
