The chip industry articles I have seen say that 4nm is not mean fully smaller than 5nm and really can be just considered a version of 5nm. I don’t have the background to give you more than that but the message has been consistent across multiple tech writers. You can see it in the smaller performance gains of 4nm A16 chips vs 4nm A15 chips from Apple.
