It looks like Apple and AMD have managed to completely get rid of Intel components in their laptops.
Intel doesn’t just make processors and chipsets. The company also produces various controllers, including USB retimers. Previously, Apple used Intel retimers in its MacBooks, and the same applied to laptops based on AMD processors.
Now, a disassembly of the new MacBook has revealed that Apple has developed its own USB4 retimer labeled U09PY3. There are no details regarding this chip yet, but Apple did not have such a solution before.
The latest AMD Rembrant APU-based laptops use a different retimer, Kandou’s KB8001 Matterhorn.
