I doubt they’d implement PCIe since they don’t need that for their baked in GPU to talk to their baked in CPU.

- avian 6y agoThe slides shows an external "Thunderbold controller" chip. Seems like something they would have hanging off a PCIe bus.
- gumby 6y agoMinor point: they could be talking to the controller itself over some other internal bus. But as TB is PCIe this comment isn't intended to contradict your core point.
- crgwbr 6y agoThe slides explicitly mentioned PCIe support. They just don’t make any M1 machines with standard slots yet.
- solarkraft 6y agoThe iPhone talks to its storage through NVMe, which is based on PCIe, suggesting to me that they already have the infrastructure.
