This should come as no surprise. Andrew Orlowski:
Apple will abandon Intel processor chips for its Macs in favour of homegrown Arm-based chips
Other than ‘duh,’ why? Three basic reasons:
First, today’s mobile chips are powerful, with dedicated GPUs, math and AI accelerators, and several cores spinning up and down depending on how much work is to be done. Secondly, Apple’s homegrown A-series chips used in its iPhones are now extremely competitive, making the switch from Intel x86 to its own Arm-compatible silicon more financially attractive as Apple controls the supply chain and can enjoy scale advantages. Apple has an Arm architectural license, meaning it can cook up its own Arm CPU cores as required on its own, and has a strong internal silicon design team – the ingredients needed to craft competitive mobile and potentially desktop chips.

And thirdly, it reduces risk, given Intel’s ongoing supply issues.
