“Please would u be so kind to tell me that the thunderbolt 3 port is PCIe 4 lane or 2 lane connection and even if it is 2 lane is it compatible with egpu with a data transfer rate of 32 gb?”

• The Thunderbolt port on this device is a 2 lane version. As to supporting an external GPU, that will depend on the requirements of the GPU. We recommend you check with the manufacturer of the eGPU for their requirements.
