How do I know if my laptop supports Thunderbolt 3?

Many people have been asking how do I know if my laptop supports Thunderbolt 3? This article will help you figure out how to know if your laptop has the right hardware for this type of connection. Thunderbolt is a high-speed data transfer protocol that allows devices to connect using a single cable and can support speeds up to 40 gigabits per second.

Thunderbolt was first developed by Intel Corporation and then later adopted by Apple in 2011 with its release of MacBook Pro models. The newest version of Thunderbolt is 3. It’s twice as fast as the original, so it’s important that your laptop be able to take advantage of these speeds!

To find out how much speed your computer supports, plug in an external drive via USB in order to transfer some files.

The speeds should show how fast data can be transferred from one device to another, and how quickly the drive is detected on your computer’s desktop.

If you don’t have an external hard drive handy and want to test out how much bandwidth is supported by Apple products such as MacBook Pro models with Touch Bar but don’t have any other devices to test how fast the connection is, you can use a site such as and choose the download option.

For instance, if it takes a few seconds for the external hard drive to load up after connecting via USB port or Thunderbolt cable, then you know that your laptop supports a maximum speed of 20 Gbit/s (or gigabytes per second).

If this time decreases drastically while still using the same type of connection between devices, it means your laptop will support 40 Gbit/s speeds!

What is Thunderbolt 3?

In terms of appearance and plugging, Thunderbolt 3 ports are almost exactly like USB-C ports. Although USB-C is not as fast as Thunderbolt 3, it can accomplish many of the same tasks. Thunderbolt 3 is essentially USB-C over Thunderbolt.

Thunderbolt 3 allows up to 40 Gbps of data transfer through USB-C devices, so any USB-C device can be connected to a Thunderbolt 3 port on a computer. Compared to USB-C, Thunderbolt boasts four times the speed of its fastest port, 20Gbps.

Further, Thunderbolt 3 makes it possible to connect multiple displays to your Mac simultaneously (for example, two 60Hz 4K monitors) and transfer data much faster than USB-C. Furthermore, Thunderbolt 3 can be used to connect external monitors and expansion docks to your Mac and transfer data much faster than USB-C.

Check the documentation for your PC

how do I know if my laptop supports Thunderbolt 3? Thunderbolt is a proprietary interface developed by Intel that can transfer data at speeds of up to 40 gigabytes per second.

The cable itself is only an inch wide and the port is reversible so it doesn’t matter which way you plug it in. It also gives your computer four lanes of PCI Express, or 20Gbps, for standard data transfers like video files.

For laptops with Windows installed on them, there are two ways to determine whether they have support for Thunder bolt. First, check PC specifications directly from Microsoft’s website under the hardware section – look specifically for the “expansion slots” option; this will list any connectors available on your machine including how much bandwidth they have.

Second, look for a Thunder bolt logo on your laptop; this is usually found near the power button or under the sticker with the model and serial number.

Check your USB-C port

– Check how many ports your laptop has on the side of it. If you have one or two, then they are probably USB Type-C and will not support Thunder bolt

If you find yourself with a single port that’s USB C and Thunder bolt port compatible, there is no need to upgrade because only Macs come equipped with this type of cable.

Otherwise, if you have more than one USB-A port (Type-A) like most laptops these days; then yes – your laptop can be upgraded for less than $200 USD by purchasing an adapter/cable from Amazon or other eCommerce sites as well as some brick & mortar stores such as Best Buy.

This would take care of any compatibility issues so that all devices can be connected to the laptop.

Check the Thunderbolt 3 compatibility list

Here’s how to know if your laptop is compatible with Thunderbolt port:

– Check the product specifications of any new computer or device you’re looking at purchasing. If it says “Thunderbolt™ v” or has a thunderbolt icon next to it, then that device should be able to work with Thunderbolt devices like external hard drives and video cards.

– Older computers can determine compatibility by checking for an Intel® processor on the label (Intel Core iX processors from 2011 onwards are all compatible). Alternatively, check online using manufacturer specs.

– Apple products such as MacBooks have been equipped with Thunderbolt since 2012, while PCs typically need an add-on card installed in order for them to work properly. Windows laptops may also only be able to use it when plugged in, which is not how thunderbolt port was designed.

How To Check If My Laptop Has Thunderbolt port 3?

While Thunderbolt 3 devices do not have the Thunderbolt 3 logo, USB-C devices do support Thunderbolt 3. However, Windows PCs with USB-C ports are no guarantee that Thunderbolt 3 will work as well.

Thunderbolt 3 devices can also be connected to USB-C ports that are fully compatible with USB 3.1, and USB 2.0. Before connecting a UAD Thunderbolt device to your computer, ensure that the port supports Thunderbolt 3.

Through Thunderbolt port or Thunderbolt 2 ports on your Mac, devices with Thunderbolt compatibility can connect to this cable for transfer speeds of up to 10Gbps.
