For CPUs, they are still licensing ARMs cores, of course with their own modifications, and they bought Intel’s modem businesses, which likely gave them the patents they needed. GPUs I can’t speak to on this though.

> For CPUs, they are still licensing ARMs cores

To be clear here, Apple doesn't actually license any cores from ARM - they've got an architectural license and implement their own cores. Licenses for cores are a different thing.

for gpus i believe they license ip from PowerVR/Imagination
