Raio 3
Meu sistema tem o conector Thunderbolt 3, USB 3.1 Gen 2 Type-C. Eu uso-o para conduzir uma segunda TV HDMI através de um adaptador DisplayPort para HDMI.

Resumo
Parece que você não tem o Thunderbolt 3 nem o USB 3.1 Geração 2. Você tem USB 3.1 Tipo C Generation 1.0, que é de 5 Gbps (480 MB / s) na mesma velocidade do USB 3.0.
A melhor maneira de descobrir é procurar a imagem "thunderbolt" ao lado da entrada USB Type-C no seu computador. No entanto, mesmo assim, pode ser apenas duas pistas PCIe e não quatro (de acordo com alguns sites que eu li hoje à noite).
Veja o PCIe para mais informações

Olhando os detalhes abaixo, vemos que a GPU nVidia pode ter no máximo 16 pistas PCIe com velocidade Gen 3.0, mas atualmente está usando 8 pistas. NVMe M.2 O Samsung SSD está levando 4 pistas PCIe a velocidades Gen 3.0. Outros dispositivos para obter 1 pista PCIe a velocidade 3.0 ou menor.
O dispositivo 1c.0 -02 parece servir ao Thunderbolt3, levando 4 pistas PCIe a velocidades Gen 3.0. A descrição acima diz "Alpine Ridge". No entanto, quando você executar sudo lspci -tv , a descrição será alterada:
+-1c.0-[02-3a]----00.0-[03-3a]--+-00.0-[04]--
| +-01.0-[05-38]--
| \-02.0-[39]----00.0 Intel Corporation Device 15b5
Quando você google 15b5 confirma que é o Intel Thunderbolt 3!
Há outras informações interessantes abaixo, como o limite de energia da nVidia de 75 Watts. Ethernet e WiFi limite de energia de 10 watts, mas ainda SSD tem um limite de 25 watts que parece alto. O limite de potência Thunderbolt3 é de 25 watts, o que faz sentido para os dispositivos de carregamento.
O relatório abaixo teve que ser truncado porque não caberia no tamanho máximo da mensagem Ask Ubuntu 30KB. Deixei os detalhes relevantes que espero que complementem a impressão da árvore acima.
