I'm working on a home network project aiming for the quickest possible link between my devices. My primary setup is a Lenovo Legion Y540, which only supports gigabit Ethernet natively. The other machine is a Threadripper with built-in 10 gigabit connectivity. While speed isn't the top priority for sending files or running applications, I still want a solid connection between them to avoid long delays—like waiting five hours for a document to transfer. I'll also need to connect remotely and run OpenGL programs over the network. My laptop has a USB 3.1 Type-C port, but it isn't a Thunderbolt port. Would this still function? Are there any 5 gigabit Ethernet adapters available? Thanks in advance for your help—I'm ready to clarify anything you need.
Reviewed it recently and the conclusion is no. The best external high-speed option is 10G over fiber, which requires a large external device. It seems a USB 3.1 Gen2 to 10GbE chip will be available soon, but that promise has been made for at least a year already.
It’s possible to purchase an adapter and continue using it even if it isn’t designed for a Thunderbolt 3 port. You might experience reduced performance compared to the advertised specs, but it could still function at least through your Ethernet jack. The Thunderbolt requirement depends on what you need to achieve.
I understand you're looking for an alternative that's not exactly what I initially sought but is more convenient than before. This item fits the 2.5G speed range and offers compatibility across multiple devices, including Mac, Windows, and Linux. You can find it here: Plugable 2.5G USB C and USB to Ethernet Adapter, 2-in-1 Adapter for USB C/Thunderbolt 3 or USB 3.0, USB-C to RJ45 2.5 Gigabit LAN.
The main constraint is usually whether your desired product can be built with existing technology, rather than lack of demand.
