No they do not, however, it has never been totally clear to me if the TB-Pcie bridge they use in eGPU enclosures provides x16 slot and the "x4 equivalent speed" bottleneck is in the TB link, or if it's physically an x16 slot that only has x4 wired up. If it's the former, it will work.
- wtallis 3y agoLooking through the specs on ark.intel.com, the Thunderbolt controllers that specify PCIe lane counts say at best they support one x4 or four x1 links, so any eGPU enclosure using those would need to connect the Thunderbolt controller to a large and expensive PCIe packet switch in order to provide more than four lanes of any speed to a GPU.
