As noted by Twitter user SkyJuice, this component change was spotted in an iFixIt Teardown last week, and it marks a sad milestone for Intel with regard to its Apple relationship. In the zoomed detail motherboard pic, you will notice two chips which carry the codename ‘U09PY3’. Apparently, previous MacBooks were using Intel’s JHL8040R Retimer chips for USB4 and Thunderbolt support.Partner with the experts to power your business with solar.

Apple eliminates the final pieces of Intel and AMD silicon Rembrandt Adopts the Style The final bits of Intel silicon have been removed by Apple from its Mac computers. IFix is a specialist in repair instructions and tools. It recently disassembled an M2 processor model MacBook and found that the Intel USB4 timing chips from earlier models had been replaced with another brand.
We don’t know who has made the new U09PY3 USB4 retimer chip, The source indicates it is a custom design, and we can’t get any further information from the markings in the image. Apple hasn’t said anything publicly about this change, and it isn’t expected to. It will have probably changed this chip for supply chain or cost reasons. Another reason behind a switch could be dissatisfaction with the Intel JHL8040R retimer, but again we haven’t heard any mutterings about this.
Regular readers will know of Intel’s deep ties with the USB4 standard, which was built on the foundation of Thunderbolt 3. Thus USB4 supports up to 40 Gbps transfers, DP Alt mode monitor connectivity, some Thunderbolt 3 device compatibility, and up to 100W power delivery. Please note the ‘up to’ stats, and don’t mistake them for minimums. For a deeper dive into USB4 check out our USB4 explainer article, and another article we created with a simple table comparing the differences between USB4, USB 3, Thunderbolt 4, and Thunderbolt 3.

On the topic of keeping Intel outside, SkyJuice also noted that AMD’s newest Rembrandt laptops have eschewed any Intel USB4 relationship. Instead, AMD has decided to go for retimers such as the KB8001 ‘Matterhorn’ from Swiss startup Kandou. This company claims its USB4 retimer chips are “deployed in products from five of the top six PC OEMs.” Moreover, its USB4 retimer is compatible with all SoC platforms.
