"I know Apple engineers working on the phone"
Groan. Come on. Cite one. A single "Apple engineer" to support this ridiculous claim of insider knowledge. What year do you think it is?
You understand that the SoC and I/O blocks are largely shared between the Mac and the iPad / iPhone now, right? This invention of some big bifurcation is not reality based. The A14 SoC (which became the foundation for the Mac's M1) had I/O hardware to support USB-C all the ways back to the iPhone 12. Which makes sense as this chipset was used in iPads that came with USB-C.
Pretty weird for hardware that is largely the same to "not like each others standards".
The I/O blocks are similar, but very much not the same between the different Axy/Mz chips.
They're different even between A19 Pro in an iPhone Air and the one in 17 Pros! The Air one doesn't support 10Gbps USB-C.
Well sure, they're iterating between models. But in many cases they're quite literally copy/pasting designs. Any imagined separation between the hardware teams is fantasy based. The comment I replied to is nonsensical.
"They're different even between A19 Pro in an iPhone Air and the one in 17 Pros"
The SoC and I/O blocks are quite literally identical. An A19 Pro is an A19 Pro, aside from binning for core disables. The difference is in the wiring and physical connector on the device which puts a ceiling on the features supported, one of which is 10Gbps. The Air famously includes some new "3D printed" super thin Titanium USB-C port, using the 4 pins rather than the "pro" 9 pin 10Gbps capable connector. The SoC is identical, they just only wired it up for USB 2.0.
