I thought Apple gets exclusive access to the latest node for the first 1-2 years. Is that not the case?
No. That's not the case. Maybe for a few months only.
Correct me if I'm wrong but didn't TSMC launch N3 in 2022, and still only Apple uses this latest/smallest node.
Both AMD and NVIDIA are using N4.
Apple, Mediatek, Qualcomm, Intel
