IDG does the numbers:
Apple does not have a large gap to overcome. The company last year shipped about 176 million processors in devices such as the iPad and iPhone, representing a 13.5 percent market share. Intel took the top spot with 181 million processors shipping in mobile products such as laptops, a 13.9 percent market share.
The elephant in the room is Samsung, obviously, which IDC somehow did not mention as part of Apple’s processor supply chain. It makes 100-percent of Apple’s iOS device processors and—somewhat comically—a smaller percentage of the processors in its own popular smartphones. If the numbers above are correct, Samsung probably fab more than Intel by number already.
To mix it up more: Samsung and Apple make higher priced Intel-based chip PCs, as well.
