These are exciting times for those who design Apple’s chips including the A-series Application Processors used in the iPhone. The iPhone 15 Pro and iPhone 15 Ultra will both be powered by the A17 Bionic which will be the first chip produced by leading foundry TSMC made using its 3nm process node. The improvement in transistor density will lead to a higher transistor count estimated to be in the range of 20 to 24 billion transistors. That compares with the 16 billion transistors inside the A16 Bionic.
