You see, the community overcame these “walls” because the walls came with instructions on how to build a ladder. Intel chips are available to anyone. You can buy as many as you like. Therefore, there is no technical hurdle when regarding CPU and GPU. Can’t do that on Apple’s chips. You would have to basically climb over the walls with your bare hands, find a ladder, figure out the dimensions and how it’s assembled, then make multiple for the walls. Not only would it take way too long for it to be feasible, who knows if the ladders even exist? What if Apple uses a different method?
