Apple senior engineer Gerard Williams III has left Apple in February this year, which will be a big loss for Apple.
Williams joined the company in 2010 as the chief architect of Apple's CPU and SOC development. He designed the core of the A7 chip, and the A7, the world's first 64-bit mobile processor, debuted on the iPhone 5s. Based on the success of A7, Apple continues to introduce a variety of A-series chips, each of which uses Williams' core design, from A7 to A12X, all by his team. In the meantime, Apple's A-series processor performance has maintained a leading edge for Android.
After nine years of work, Williams left Apple. The impact of his departure on Apple is a focus of attention, because Apple is constantly developing its own custom chip, the departure of the chief engineer may also exacerbate the dilemma of the iPhone in the future, and the chip is also facing the test.
Williams is not the only platform architect who left Apple in recent years. In 2017, Google dug Manu Gulati from Apple. Gulati has served as an advanced chip architect for Apple.
