如何检查（通过软件）我的USB 3.1gen2 Type-C端口是否支持Thunderbolt3？
我有一个带有usb 3.1gen2 Type-C端口的华硕N752VX-GC234，有些网站称它支持Thunderbolt3，有些人说不支持。
我该如何检查以确定？ 我可以用这个命令吗？

我发现这篇post说这个芯片组不允许同时10Gbps并且不支持Th3。 这是答案吗？
谢谢，卢卡

我的系统有Thunderbolt 3，USB 3.1 Gen 2 Type-C插孔。 我用它通过DisplayPort到HDMI适配器驱动第二台HDMI电视。

摘要
看来你没有Thunderbolt 3和USB 3.1 Generation 2.你有USB 3.1 Type C Generation 1.0，它的速度是5 Gbps（480 MB / s），速度与USB 3.0相同。
找出答案的最佳方法是在计算机上寻找USB Type-C插孔旁边的“霹雳”图片。 然而即便如此，它可能只有两个PCIe通道而不是四个（根据我今晚读到的一些网站）。

查看下面的详细信息，我们看到nVidia GPU在Gen 3.0速度下最多可以占用16个PCIe通道，但目前正在使用8个通道。 NVMe M.2三星SSD采用Gen 3.0速度的4个PCIe通道。 其他设备在Gen 3.0速度或更低时采用1个PCIe通道。
设备1c.0 -02看起来可能为Thunderbolt3服务，以Gen 3.0速度获取4个PCIe通道。 以上描述为“Alpine Ridge”。 但是，当您运行sudo lspci -tv ，描述会更改：

当你谷歌15b5它确认它是英特尔Thunderbolt 3！
下面还有其他有趣的信息，例如nVidia功率限制为75瓦。 以太网和WiFi功率限制为10瓦，但SSD的限制为25瓦，这似乎很高。 Thunderbolt3功率限制为25瓦，这对充电设备很有意义。
下面的报告必须大量截断，因为它不适合Ask Ubuntu 30KB邮件的最大大小。 我留下了相关的细节，我希望补充上面的树打印输出。
