Apple and AMD remove all traces of Intel hardware from their M2 MacBook and Rembrandt laptops


Apple and AMD have removed all signs of Intel silicon used in the M2 Mac and Ryzen laptop lines. The iFixit website published a blog post in which the group dissected a new M2-based MacBook, revealing that Intel’s USB4 retimers, seen in previous models, have been silently removed and replaced with retimers from Intel. another party.

Intel Silicon is pulled from Apple and AMD, dropping Intel USB4 solutions

twitter user SkyJuice first noted iFixit’s dissection from last week. Intel Retimer chips that used USB4 and Thunderbolt support were used in older MacBook models.

The USB4 Retimer chip codenamed U09PY3 is a custom design by Apple itself. Additionally, Apple hasn’t officially released details of the unknown chip, but it looks like the company will likely keep quiet for now. Speculation is that Apple replaced the chip either to reduce cost or due to supply chain constraints. However, another reason would stem from Apple’s distaste for the Intel JHL8040R retiming chip.

The Twitter user goes on to note that the latest AMD Rembrandt-based laptops have also removed all use of the Intel USB4 retiming chip. The company chose to turn to Swiss startup Kandou to use its KB8001 Matterhorn retiming chip. Kandou claims that its USB4 retiming chips are “in the products of five of the six major PC OEMs”. Another notable feature of Kandou is that their chips are currently compatible with all SoC platforms.

Built on the foundation of Thunderbolt 3, Intel has been using the USB4 standard for quite some time. Intel USB4 supports transfer speeds of up to 40Gbps, a minimal amount of compatibility with Thunderbolt 3 devices (which we just mentioned), DisplayPort Alt mode monitor connectivity, and allows up to 100W of power delivered.
