Apple has removed the last wreckage of Intel Silicon from Mac computers. Repair procedure and tools specialist iFixIt recently disassembled one of the latest MacBooks (M2 processor model) and discovered that the previous generation Intel USB4 timer chip was being replaced by another brand.
As Twitter users pointed out SkyJuiceChanges to this component I fix Last week’s disassembly marks a sad milestone for Intel regarding its relationship with Apple. In the zoomed detail motherboard photo, you will notice two chips with the codename “U09PY3”. Apparently, previous MacBooks used Intel’s JHL8040R retimer chip to support USB4 and Thunderbolt.
I don’t know who made the new U09PY3USB4 retimer chip. The source indicates that it is a custom design and no further information can be obtained from the markings on the image. Apple hasn’t said anything publicly about this change, and it’s not expected to happen. You probably changed this chip for supply chain or cost reasons. Another reason behind the switch may be dissatisfaction with the Intel JHL8040R Retimer, but I haven’t heard any tweets about this.
SkyJuice also mentioned that AMD’s latest Rembrandt laptop is avoiding a relationship with Intel USB 4 on the topic of keeping Intel external. Instead, AMD has decided to adopt a retimer such as the KB8001 “Matterhorn” from Swiss startup Kandou.This company Claim The USB4 retimer chip is “introduced in the products of five of the top six PCOEMs.” In addition, its USB4 retimer is compatible with all SoC platforms.
The average reader will know Intel’s deep connection to the USB4 standard, which is built on Thunderbolt 3. Therefore, USB4 supports up to 40 Gbps transfer, DP Alt mode monitor connection, compatibility with some Thunderbolt 3 devices, and up to 100 W power supply. .. Pay attention to the “maximum” stats and do not mistake it for the minimum. For more information on USB4, see the USB4 description article and another article created using a simple table comparing the differences between USB4, USB 3, Thunderbolt 4, and Thunderbolt 3.
