This is true for those laptops until Thunderbolt is supported and thus you can connect a supported PCIe GPU such as an AMDGPU via an external Thunderbolt-PCIe enclosure. How good the actual performance is would need to be checked then. It should be good considering it's 22gbps of full duplex PCIe data bandwidth, but needs to be tested.
