It appears that Apple and AMD have successfully eliminated all Intel components from their laptops.
Intel isn’t limited to chipsets and processors. Intel also makes a variety of controllers, such as USB retimers. Apple previously used Intel retimers to make its MacBooks. The same applies to AMD processor-based laptops.
A disassembly revealed that Apple has created its own USB4 retimer, labeled U09PY3. Although Apple has not provided any details about this microcircuit, it does have a solution.
The AMD Rembrant APU laptops are powered by a new retimer, Kandou KB8001 Matterhorn
