It is only Macs that are using Intel processors. Ninety percent of Apple's product line is already using Apple-designed SoC so the iPad does not need to migrate to ARM.
iPads are already running Apple SoC and have done so since their inception. In fact, the iMac Pro used for the demos at the WWDC had its Intel processor removed and replaced with the A12X from an iPad Pro and was running Big Sur in native Apple SoC mode.
At this point, my question is how much of the
original ARM design remains in the Apple SoC other than the instruction set?
