What is Thunderbolt?

Thunderbolt is a new connection protocol on computers, jointly developed by Apple and Intel and launched in 2011. Currently, Apple has completely replaced other connection protocols with thunderbolt for its products.

Thunderbolt uses PCI Express (data transfer) and DisplayPort (image transfer) into a single serial connection (using the popular USB Type-C connection standard), and also charges the device. So with just one cable, you just connect, transfer data to other devices, and charge the laptop battery very conveniently.

Thunderbolt transfers high volume multimedia data between devices with high speed (up to 40 Gbps in thunderbolt 3), low latency, high integrity. As a result, data is sent quickly without even the slightest change.

What is Thunderbolt 4? What features are there?

After the success of Thunderbolt 3, Thunderbolt 4 was born promising more improvements. Specifically, Thunderbolt 4 has both differences and similarities compared to Thunderbolt 3, performance and features are somewhat superior when compared to the USB 4 standard.

Possibility

Thunderbolt 4 is supported by Wi-Fi 6 GHz and Bluetooth 5.0, and promises to be supported by Intel’s Tiger Lake mobile processors soon. Laptops using Tiger Lake chips will be released at the end of 2020, so through 2021 customers interested in the applicability of Thunderbolt 4 will have more choices.

Besides, the Thunderbolt 4 8000 series will work with all current Thunderbolt 3 PCs and similar devices.

Working performance

Thunderbolt 4’s transfer speeds are no faster than Thunderbolt 3 and operate with a maximum throughput of 40Gbps. However, Thunderbolt 4 requires a PCIe bandwidth speed of 32Gbps – 2x Thunderbolt 3, so common computing tasks related to data retrieval and storage can be significantly accelerated.

Speciality

Thunderbolt 4 has a lot of features, from enabling discrete graphics to accessing Ethernet networks. Besides, Thunderbolt 4 has now added the ability to support cables up to 2 meters long and you can also connect to 8K displays.

Currently, Thunderbolt 4 possesses some notable features as follows:

• Video data is at least twice that of Thunderbolt 3. This will allow support for two 4k or 8k displays if needed.
• Dock support with up to four Thunderbolt 4 ports , more than required by Thunderbolt 3.
• The wake-up feature allows you to instantly wake up your computer by tapping a keyboard or mouse when connected to a Thunderbolt dock (this feature does not work with Thunderbolt 3).
• Prevents hacking into memory through high-speed data connections on computers and data theft. For Thunderbolt 4, Intel creates a separate memory bag when transferring data to avoid hacking.
