I've been wondering if Apple might get in to the dedicated GPU game. First replacing the integrated Intel gpu in the lower end machines with their mobile gpu chip designs, then maybe tackling a scaled up version? They used to use PowerVR GPUs in the iPhone line, but I think (?) they're designed in-house now. They have their own Metal graphics API already. And they're on a 7nm process from TSMC.
