A few years ago, we were frustrated with transferring data because it took a long time to transfer smaller files.
What do the peripherals?
The USB port does not work properly and always faces data transmission and connection problems in most cases.
Nowadays, technology is developing very fast, and data transmission has become so quickly.
We can transfer large files in less time without getting frustrated.
In addition, if you have a large monitor at home, you can enjoy it by connecting to a laptop or PC.
You can enjoy any movie program or audio through the Thunderbolt port.
Before buying any gadgets such as laptops, desktops, PCs, etc., you must pay attention to what ports and connections are included.
The latest Thunderbolt ports are high-speed; if you don’t choose all of these fastest connections in your personal computer, you will feel a bit low after two or three years.
What is Thunderbolt 3?
In early December 2015, Intel launched Thunderbolt 3, a particular port that connects to a USB Type C connector. Thunderbolt 3 is the successor to the Thunderbolt 2 port, adding many new features.
With the maturity of standard port performance and fewer adapters, Thunderbolt will be welcomed by most users.
The goal of Thunderbolt is to provide users with desktop-like performance on a laptop computer, which is difficult to achieve through USB. In addition, it can transmit fast data through a single port and share video output with peripheral devices.
Using an older USB port is too bad because Thunderbolt 3 is high-speed. It is much faster than the current maximum speed of USB and is the same as Thunderbolt 4 so far.
A few years ago, if you put the connector in the USB cable, you had to connect it carefully because some pins might damage it. With the Thunderbolt 3 port, you don’t need to bother to connect to other ports.
Features of Thunderbolt 3
Many unique features have been added to Thunderbolt 3.
Also, It is a superset of USB-C; you can plug a USB-C-only device into the Thunderbolt 3 port.
The Downgrade is You can’t connect a 2-meter lengths USB cable through Thunderbolt 3.
The main features of Thunderbolt 3 include:
- It transmits data at a speed of 40Gbps, which is much faster than USB-C.
- You can connect a 4K monitor or a 5K monitor to route video and audio output.
- It supports Gigabit Ethernet.
- We can connect multiple devices connected for serial connection and access by one computer.
- With the Thunderbolt 3 port, you can connect to any docking station, device, and PCle GPU at 10Gbps.
- Compatibility: Thunderbolt 3 can replace USB 2.0, 3, 1, 3.2 ports.
How Thunderbolt 3 Made?
The Thunderbolt 3 port looks the same as the circular USB-C reversible connector. In fact, from the plug-in point of view, the connector is physically the same.
Thunderbolt 3 can complete all the functions of USB-C and can replace USB 2.0, USB 3.1, and USB 3.2 ports.
Thunderbolt 3 provides data transfer at a higher speed of 40 Gbps, which is twice the speed of previous standards such as Thunderbolt 2, USB 3.
What is Thunderbolt 4?
In 2020, Thunderbolt launched a new version of Thunderbolt 4 with an Intel Tiger Lake processor. Its design is the same as the Thunderbolt 3 USB Type-C reversible connector. Some new features not available in the previous version have been added.
A Thunderbolt 4 port can complete all connections, including USB 2.0, USB 3.1, USB 3.2, and Thunderbolt 3.
Everything you need to know is a port that is backward compatible with Thunderbolt 3 and USB 3.
Features of Thunderbolt 4
Thunderbolt 4 Port adds many new features, such as
- With the Thunderbolt 4 port, you can connect any USB or Thunderbolt cable, no matter its size.
- Here, connecting a peripheral with a Thunderbolt IV laptop or personal computer through the docking station can also be slid out by the connected device.
- Thunderbolt 4 supports two 4K displays or one 8K display/display.
- Able to continuously transmit data at a rate of 40Gbps bandwidth.
- It supports docking stations with up to four Thunderbolt 4 ports.
- Thunderbolt 4 provides direct memory access (DMA) protection to prevent physical DMA attacks.
- High-speed charging support: It Supports 100W Power Delivery charging to other devices, such as smartphones, PCs, etc.
- The PCIe data speed has doubled from the previous version to 32Gbps.
How is Thunderbolt 4 made?
Thunderbolt 4 is the latest and fastest special port type. It is made on the basis of Thunderbolt 3’s innovation and can use a single USB-C cable to transfer data, video output to the monitor and power the device.
Thunderbolt 4 is the most comprehensive solution provided by the USB-C connector.
It must be ensured that all functions provided by Thunderbolt 3 are met in 4.
Visually, this Thunderbolt 4 is similar to the USB 4 or Thunderbolt 3 connector that uses round reversible Type-C.

Thunderbolt 3 Vs Thunderbolt 4: Key Differences
Thunderbolt 3 and Thunderbolt 4: Data Transfer
Through these two ports, you can quickly transfer data at a rate of 40 GB per second. However, with Thunderbolt 4, you can consistently transfer data at high speed, but not in Thunderbolt 3.
Thunderbolt 4 and Thunderbolt 3: Device Support
By connecting Thunderbolt 4, you can enjoy up to four TB4, but not in Thunderbolt 3.
You can connect additional peripheral devices through these two ports, such as USB, mouse keyboard, monitor, etc. The most important thing is that you can also connect an external GPU, which is a unique feature that everyone likes.
Thunderbolt 3 vs. 4: Display Connection
One of the highlights of Thunderbolt 4 and Thunderbolt 3 is their versatility. In addition to providing breakneck transfer speeds, the bandwidth of Thunderbolt 4 can drive up to two 4K or one 8K displays at a frequency of 60 Hz, but Thunderbolt 3 only supports one 4K display.
Thunderbolt 4 and 3: Power Transmission
Thunderbolt supports up to 100W of power; this means you can charge external devices that support fast charging (such as smartphones or any other devices), but not in Thunderbolt 3.
Thunderbolt 4 and Thunderbolt 3: Security
Thunderbolt 3 does not provide any security measures, which means that each other’s data will be shared without permission when you connect any other devices.
However, DMA protection based on Intel VT-d has provided the necessary security in Thunderbolt 4, and you have no right to access any data without permission.
Thunderbolt 3 and Thunderbolt 4: Other Features
The Thunderbolt 4 is equipped with this facility, which means your laptop or PC can sleep and slide out on any external device.
Thunderbolt 3 has a minimum requirement of Pcle 16 Gbps, but the minimum requirement in a Thunderbolt 4 PC or laptop is Pcle 32Gbps.
Almost all Thunderbolt 4 laptops are the most expensive, but Thunderbolt 3 laptops may be a better choice at a lower price.
