What Is Thunderbolt 3 And How Does It Differ From Previous Versions?
Thunderbolt 3 is the latest generation of the Thunderbolt interface, which provides fast speeds and versatility in a single port. It uses the reversible USB-C connector and offers significant improvements over its predecessors, Thunderbolt 1 and Thunderbolt 2. While previous versions were limited to 10 Gbps and 20 Gbps speeds, Thunderbolt 3 boasts an astonishing 40 Gbps data transfer rate, making it the fastest port available on the market.
Thunderbolt 3 also supports Power Delivery (PD) up to 100W, allowing users to charge their devices quickly and efficiently. Another key feature is its compatibility with USB, DisplayPort, and PCIe protocols, making it an incredibly versatile port that can connect to a wide range of devices. In short, Thunderbolt 3 is a game-changer in the world of connectivity, offering unparalleled speed, convenience, and compatibility.
How Does Thunderbolt 3 Achieve Its Blazing-fast Speeds?
Thunderbolt 3’s incredible speed is made possible by its use of the PCIe 3.0 x4 interface, which allows it to transfer data at an astonishing 40 Gbps. This is four times faster than the previous generation of Thunderbolt, and double the speed of the fastest USB 3.1 Gen 2 port. To put this in perspective, Thunderbolt 3 can transfer a 4K movie in under 30 seconds, making it ideal for video editors, photographers, and other professionals who require rapid data transfer.
Furthermore, Thunderbolt 3’s implementation of the PCIe 3.0 x4 interface enables it to support two 4K displays or one 5K display, making it an ideal solution for those who need multiple displays or high-resolution monitors. The fact that Thunderbolt 3 can also transmit power and data simultaneously, makes it a highly convenient and efficient way to connect devices.
What Devices Support Thunderbolt 3?
Thunderbolt 3 is widely supported by many modern devices, including laptops, desktops, and peripherals. Many of the latest MacBook and MacBook Pro models feature Thunderbolt 3 ports, as do certain Windows laptops and desktops from manufacturers like Dell, HP, and Lenovo. Additionally, Thunderbolt 3 is also supported by a range of peripherals, such as external hard drives, displays, and docking stations.
In order to take advantage of Thunderbolt 3, users will need a device with a Thunderbolt 3 port, as well as a compatible Thunderbolt 3 cable and a device or peripheral that supports the protocol. Fortunately, the adoption of Thunderbolt 3 is widespread and continues to grow, making it an increasingly accessible technology.
Can I Use Thunderbolt 3 With Older Thunderbolt Devices?
While Thunderbolt 3 is a significant improvement over its predecessors, it is still backwards compatible with older Thunderbolt devices. This means that users can still connect their older Thunderbolt peripherals to a Thunderbolt 3 port using an adapter or cable. However, it’s important to note that the speed and capabilities of the older devices will be limited to their native specifications, rather than the faster speeds offered by Thunderbolt 3.
For example, if you have an older Thunderbolt 2 peripheral and connect it to a Thunderbolt 3 port, it will still operate at its native 20 Gbps speed, rather than the 40 Gbps speed offered by Thunderbolt 3. However, this backwards compatibility does provide users with more flexibility and freedom to upgrade their devices over time.
How Does Thunderbolt 3 Compare To USB 3.1?
Thunderbolt 3 and USB 3.1 are both high-speed interfaces, but they have distinct differences in terms of speed, versatility, and functionality.
