The article buries the lede halfway to the earth’s mantle so here it is:
> The Titan Ridge card creates a Thunderbolt 3 link given a PCIe 3.0 x4 interface. An eGPU connector provides a PCIe 3.0 x4 interface given a Thunderbolt 3 link. Could it be possible to drive one off the other in a demented daisy-chain? Could I create a Thunderbolt-over-Thunderbolt connection?
What a pointless blog. “I don’t know why Thunderbolt exists. Here let me daisy chain PCIe and Thunderbolt devices to try and break it. Oh, it works, I must be cursed.”
