> They don’t make storage chips or RAM chips They use 3rd party NAND and DRAM but the controllers for each are part of their custom SoC (along with their CPU and GPU) and things are a little bit different than how anyone else does it with integrated solutions as a result. I believe the USB/thunderbolt are part of their custom SoC too. Some of the microcontrollers for other functionality (secure enclave, camera/microphone processors, touchpad and the like) are outside the SoC but custom. Wi-Fi is still a standard Broadcom chip, for now at least :). It's somewhat disappointing how much cool customer hardware is limited to just Apple products to be honest.
