While everyone is all preoccupied with Thunderbolt, I came across a pure external PCI-E standard that directly lets you connect 4x or 8x PCI-E lanes via a cable (with none of that extra nonsense like USB-C or Displayport communication over the same port.) Like ExpressCard, it sounds hotswappable as well. Only problem is, it seems like no one knows about this outside of niche server applications (Supermicro as one example.) How come everyone went for the Thunderbutt route over OCuLink for eGPUs? For those who are a bit creative, I could see retrofitting a laptop with a 4x M2 slot with a card that lets you route the lanes to a OCuLink port you cut out and install on the side of a laptop, and connecting that to an OCuLink eGPU enclosure. (Something with a bit of CPU grunt like the Clevo N650DU.) Anyone else been looking at this?
