If you look at the more modern Mac laptop or the MacBook Pro you will see that the core that is being used is an intel core m3 - m7 which would be a custom take on the intel cores i3 - i7 on an actual windows PC, when you compare them, both cores come from the same company and they both have power that is indicated by their name and rank as well as the motherboards which are made to support the cores which are usually under a 64 - bit architecture as far as my concern goes
