Some pre-built desktops support Thunderbolt 3, but typically you need to buy an expansion card to add Thunderbolt 3 to a Windows desktop. On the Windows side, if you want a Thunderbolt 3 port out of the box, then you’re looking for a laptop. Apple puts the port on all its current machines, including its laptops, desktops, and all-in-ones. The easiest way to make sure you get Thunderbolt 3 is to buy a Mac. Which Computers Include Thunderbolt 3? Intel The trick is that computer makers have to support this feature in their laptops as support for PCIe graphics cards is not automatic. PCIe support allows gamers to turn a laptop without much in the way of graphics support into a pretty good gaming machine. Samsung supports daisy-chaining for monitors with USB 3.1, but generally, this feature is not as well supported as it is with Thunderbolt 3.įinally, Thunderbolt 3 can support PCIe devices such as external graphics card docks, while USB 3.1 does not. Daisy chaining is typically used to connect multiple displays, but it could also be used to chain up several monitors and external hard drives off of a single port.
If you use a USB 3.1 device as Device C, for example, then the daisy chain stops at that point.Īlso, keep in mind that your laptop will need the computing resources to deal with all those connected Thunderbolt devices. All devices have to be using Thunderbolt 3. This means you plug device A into the Thunderbolt 3 port on your laptop, and then you connect device A to device B and so on. With Thunderbolt 3, you can also daisy chain up to six additional devices to your source machine. Thunderbolt 3, by comparison, supports video out of the box. However, Alt Mode is that it’s an optional feature that OEMs have to enable. USB 3.1 Gen 2 supports video as well in what’s called “Alt Mode” where you can connect directly to a DisplayPort monitor–HDMI is also possible. You can also connect up to two 4K displays at 60Hz over DisplayPort. Thunderbolt speeds don’t just mean you can transfer a two-hour 4K video to an external drive that much faster. When using USB, the Thunderbolt 3 port is limited to the USB speeds of the connected device, not the blazing fast speeds of Thunderbolt. Thunderbolt 3 has a “fallback” option, where if it cannot communicate with a connected device as a Thunderbolt unit, then it tries the USB protocol. Now, here’s the critical point about Thunderbolt 3 and USB: A Thunderbolt 3 port can also function as a USB port, but a USB port cannot work as Thunderbolt 3. If it’s Thunderbolt 3 the lightning bolt appears as you see above. USB ports can also have lightning bolts, but these signify that the USB port is capable of charging small items such as smartphones even when the laptop is turned off. To tell the difference, Thunderbolt 3 ports, cables, and gear are typically labeled with an arrow-shaped like a lightning bolt.
