A report from The Information highlights employee retention issues inside Apple’s silicon group, with some employees sourced citing extremely long hours and stressful workloads. Apple is currently embroiled in litigation with at least two startups, Nuvia and Rivos, who have poached dozens of engineers from Apple, and who Apple claims stole proprietary information about its chip designs.
The most interesting anecdote is the claim that Apple was working on a next-generation GPU for the iPhone 14 Pro, but an engineering design mistake was found late in development which meant the plans had to be scrapped …
The report says engineers were “too ambitious with adding new features” and prototypes had much higher power draw than the simulated estimates expected. This meant the GPU would have impacted battery life too much to be usable, and incurred thermal issues. As a result, it couldn’t be used for the iPhone 14 Pro line.
The shipping iPhone 14 Pro GPU cores use a similar architecture to the cores found in the A15 chip from iPhone 13 Pro, without any big leaps to speak of. (During the September iPhone keynote, Apple briefly mentioned that the 5-core GPU had 50% higher memory bandwidth.) The new GPU would have supported advanced features such as hardware-accelerated ray tracing, according to The Information.
