Apple's senior director in platform architecture, Gerard Williams III, left the company last month after nine years, according to CNET. He might not be the most recognizable name from the tech giant, but he held a very important position for a company that's making it a point to design more and more of its own components. Williams led the development of all Apple processors from the A7, which first appeared on the iPhone 5S, to the A12X that's inside Cupertino's latest iPad Pros.
