It has to do with what the chips can support.

Compare the AMD USB channels [1] with the Intel Thunderbold channels [2]. Intel has more channels for motherboard/system manufacturers to work with.

It's such a pity AMD revolutionized bandwidth & interconnectivity on Epyc (128 lanes PCIe) , but has left consumers hanging. Threadripper HDET was 64 lanes (the Pro really was a full Epyc, 128 lanes, 8 channel memory) but now Threadripper is gone.

Meanwhile desktop & mobile have been so capped, at 20 - 24 lanes, right where we were.

The Thunderbolt 4 abilities of Intel chips is just stunning. 160Gbps of connectivity, usable for host to host connectivity... I wish AMD were trying to catch up here, wouldnt compromise their lead by being so far behind here.
