Tim Millet has been at Apple for 16 years and has served as the vice president of platform architecture since 2015. His group develops Apple’s system-on-chip architecture. In this role, Millet oversaw the rollout of the A14 chip, which is capable of 11 trillion calculations per second. That’s a huge leap over the 2017 iPhone X, the first with face unlocking, which could process 600 billion operations per second. He holds over 60 patents.
