It's the same process node used by the world's largest foundry to build the Apple A19 and A19 chipsets that power the new iPhone 17 series. In a nutshell, as the process node shrinks, so does the size of the transistors used in the component. Things could get worse next year when the foundry starts production of APs using its 2nm process node. 22.22%Samsung Foundry and TSMC's 2nm process nodes also use Gate-All-Around transistors (GAA). As for what happens after the 1.4nm process node (A14), we could see a new transistor architecture and different materials used.
