Nothing to do with that, they just have a head start in the right direction along with enough money to fund many iterations before it landed on Desktop or become accepted by 95% of people.
Qualcomm's current Snapdragon Elite Oryon 2 on Mobile, and ARM Cortex X925 or previously known as X5 are already close to Apple A17 level performance. So this is no longer something unique to Apple.
I just wish both design are more widely available. And for x86, Intel and AMD still haven't quite caught up. At least not in the next 2 years.
