One of the cooler applications of Thunderbolt is the ability to connect external GPUs. However, you lose a lot of performance that way because PCI Express has to be wrapped in Thunderbolt, and that’s inefficient. You get better performance if you simply run a wire for a direct PCI Express connection, which is exactly what the OCuLink standard is for, but you really don’t see that on consumer hardware much. Well, thanks to the modularity and open-source nature of Framework laptops, an enterprising user…
