All there is to know about the legendary Thunderbolt 4 thunderbolt port

Through a revolutionary arsenal of new laptops, ASUS recently expressed its full readiness for Intel Tiger Lake processors of the 11th generation with a precision of 10nm manufacturing, and the next ZenBook group (almost all of them) helped us provide support for the Thunderbolt 4 port. But the confusing thing is that both Thunderbolt 4, Thunderbolt 3 and USB4 will all share the same port as standard USB-C for connections to external storage and displays. So far, some users are unable to tell the difference between USB-C and Thunderbolt 3 because they rely on the same two-sided port. So if you are still unable to notice the difference between them, we recommend that you always look for the small lightning logo next to the USB Type-C ports on the side of the laptop, and if you notice its presence, this means that your USB-C port is Thunderbolt 3, which works at 40Gbps.

Speaking of speed characteristics, Intel indicated that the new Thunderbolt 4 Thunderbolt port will come at exactly the same speed as 40Gbps, which was a disappointment for those who expected to see it at 80Gbps or something like that. But at the same time, Intel confirmed that the new port will achieve real speed rates promising over the previous generation Thunderbolt 3 port, and it also provides a new set of advantages that pose a number of challenges for laptop manufacturers if they intend to host Thunderbolt 4 with their next devices. . Now, we will share with you all the information we have regarding the Thunderbolt 4 port and explain what its requirements are and how to benefit from it in the near future.

Now we will be facing two new interface standards, namely USB4 and Thunderbolt 4, and they will be supported by the Intel Tiger Lake processor chip .. Thunderbolt 4 protocol will provide support for previous data transfer interfaces, which include Thunderbolt 3, USB4, USB3, and USB2 / 1, all through the port One is USB Type-C Thunderbolt 4. It works at a bandwidth of 40Gb / s and has a number of basic requirements for hosting it in modern devices which include all of the following:

Support for the operation of two screens with a resolution of 4K or one 8K screen, without our details about the refresh rate.
Transfer data with external storage cases that include a PCIe interface at 32Gb / s instead of 16Gb / s.
Thunderbolt 4 enclosure support with four Thunderbolt 4 ports.
Charge 100-watt device batteries with at least one USB-C port.
The ability to wake devices from idle via peripherals connected to the Thunderbolt 4 port enclosure.
Provides direct access to memory protection against spyware attacks.

For starters, Thunderbolt was developed in 2011 by Apple and Intel in the form of an electronic chip codenamed Light Peak, and the MacBook Pro was the first laptop to have the Thunderbolt protocol that works through the mini DisplayPort at 10Gb / s. However, we can describe the next two generations of Thunderbolt as being more hopeful and promising than the first generation due to their ability to support PCIe 3.0, move to USB Type-C instead of mini DisplayPort and operate with 40Gb / s bandwidth.

But with regard to the fourth generation Thunderbolt 4, we did not see a noticeable change between it and its previous successor, as the bandwidth is still stable 40Gbps and the port used is still USB Type-C. The only difference between them will be how to take advantage of them and what are their basic operating requirements, as Intel confirmed the need for any device that has a Thunderbolt 4 port to support the ability to connect two 4K displays or one 8K display. Personally, I did not find at this point in particular a noticeable difference between it and the previous port, but it is expected that the Thunderbolt 4 port will be more reliable and reliable in order to achieve this better.

Thanks to the higher bandwidth with external storage, Thunderbolt 4 will be a godsend for video editors who rely on large file and data transfers between a number of devices every now and then. In addition, security features come through VT-d DMA virtualization technology in order to counteract against dangerous attacks that try to seize information from inside the RAM, where the main purpose of this technology is to confront the recent ThunderSpy vulnerability that allowed penetration of protection systems and information theft from the memory.

To the average user, Thunderbolt 4 doesn’t seem quite as promising. On the other hand, this port still fulfills the purpose and primary goal of being in the process of connecting multiple screens to the laptop or speeding up data transfers with ultra-fast external storage units.

It should be noted that the Thunderbolt 4 chip was integrated this time inside the same Tiger Lake silicon processor, which differs from previous generations as it was completely separate from the central processor. The eleventh-generation Tiger Lake processor is Intel’s first processor with a precision of 10nm manufacturing and is geared toward tablets and laptops only. If you are waiting for the next generation Intel processor for desktop devices, you should watch out for the 12th generation Alder Lake 10nm processor.

Thunderbolt 4 has additional advantages such as the ability to charge electronic devices through at least one USB-C port with a capacity of 100 watts, the ability to wake up the laptop through any peripheral device connected to the Thunderbolt 4 port, and support for 4 devices or peripherals that can be connected Via a peripheral container containing four Thunderbolt 4 ports. Support for the USB4 standard will be one of the favorite things and features in the Thunderbolt 4 port in the near future, but because both are through the same USB-C port, the user will have to understand the laptop’s features and specifications and read them closely until He knows very well which port he has in the device that supports the Thunderbolt 4 protocol, but in any case remember to always look for the miniature lightning logo.
