But I assume the SoC or the processor itself does have PCIe expansion ports, right? Internal GPUs should in theory work should the part be sold by itself.

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

The slides explicitly mentioned PCIe support. They just don’t make any M1 machines with standard slots yet.

The iPhone talks to its storage through NVMe, which is based on PCIe, suggesting to me that they already have the infrastructure.

The slides shows an external "Thunderbold controller" chip. Seems like something they would have hanging off a PCIe bus.

[gumby]

Minor 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.

Unless Apple starts selling some overpriced PCIe devices, don't hold your hopes up on this. Ram is soldered / integrated into the SoC. Tomorrow even the SSD will be (if it isn't already). Ultimately you will not be able to upgrade anything, just like your iPhone or iPad.

Apple Silicon has not yet been made available in a Mac Pro enclosure (where PCIe internal GPUs could be used). We can only guess what the story will be when it is, as no statement has been made by Apple either way.
