Thunderbolt 4 vs. USB-C: What’s the Difference?

Thunderbolt 4 vs. USB-C Featured

Let’s know in detail about the Thunderbolt 4 vs. USB-C ports.

A few years ago, the data transfer speed in any laptop or personal computer was very slow, and one could expect the data transfer rate to be as high as 1 MB to 10 MB per second.

But now technology has changed, and personal computers provide faster connections. In 2000, a special type of USB port (Power Mac G4) was introduced faster than its predecessor.

The data transmission speed of this kind of cable is very slow; the speed is only one-third of Gigabyte Ethernet.

When the first Thunderbolt was launched on the MacBook in 2013, this technology was very popular because it was challenging to transfer data.

Sometimes you used to transfer 1GB of data and wasted a lot of time. First, the Thunderbolt port starts up in partial seconds of up to 10GB.

Imagine????

That when data transfer was so tricky in the past, you can connect the camera display docking station and the external hard drive by connecting a tiny bit if there is the fastest port. How much do you want, and how helpful is it?

Thunderbolt 4 was introduced by adding some new features.

Without wasting precious time…

Let us know what the difference is between USB c and Thunderbolt 4 ports.

What is Thunderbolt 4?

Thunderbolt 4 was launched in mid-2020 and is equipped with the 11th generation Intel Tiger Lake processor. Some essential features were added, which were not included in Thunderbolt 3.

The design of this port is the same as the Thunderbolt 3 USB Type-C reversible connector.

The most important thing about this new Thunderbolt 4 port is to allow all USB ports to work in one cable, such as USB 2.0, USB 3.1, USB 3.2, and Thunderbolt 3.

What are the Features of Thunderbolt 4?

Thunderbolt 4 Port adds many new features, such as

  • With the Thunderbolt 4 port, you can connect any size USB or Thunderbolt cable.
  • Here, if you connect a peripheral device to a PC with Thunderbolt via a docking station, it can also be moved by the connected device.
  • It supports two 4K displays or one 8K display.
  • This technology can continuously transmit data at a rate of 40Gbps bandwidth.
  • Thunderbolt 4 supports up to four docking stations with the same type of ports.
  • Thunderbolt 4 provides direct memory access (DMA) protection to prevent physical DMA attacks on your device.
  • Support Power Delivery: It can support 100W Power Delivery charging for smartphones, PCs, and other devices.
  • The PCIe data speed has doubled from the previous version, reaching 32Gbps.

Benefits of Having Thunderbolt 4

The introduction of Thunderbolt 4 is that some features are not available in the previous version, such as a 2-meter cable connection. We encountered some problems, so they made improvements in solving them smoothly.

There are many advantages, such as——

1. Flexibility

It can perform different tasks simultaneously, such as connecting to an external display, transferring data, and powering compatible devices.

2. Multiple connections

If the device has a Thunderbolt 4 port, it can replace many other ports, such as Thunderbolt 3, USB, DisplayPort, and PCle.

What is USB-C?

USB C is a standard connector used for data and power transmission connected by a single cable.

From the appearance point of view, the USB C port is similar to the USB port, but it is thinner and does not need to be put down when connecting.

USB-C was developed by a group of companies in the USB Implementers Forum (USB-IF) and certified by the company in the past few years.

The most popular port and the connection is the USB-A port, which looks very similar over the years; no improvements have been made.

Except for the USB C port, no cable connector has been so much improved.

This is great when the USB port is designed to connect printers and other desktop peripherals, and it also provides a quick connection.

In addition, when USB became the standard for charging and synchronizing small devices such as mobile phones and cameras, it created a smaller interphase version in micro and mini USB connectors.

What are the Features of USB-C?

The USB C port has many benefits, especially for professional businesses, and is most beneficial for those who spend more time outside of work.

Reversible: The USB C port uses a reversible and circular connector type, which means you don’t need to be upside down; just connect the small-sized port to start working.

USB power supply: It supports a two-way power supply and can provide power from 2.5 W to 100 watts. In addition, you can clean any other equipment and graph it with your equipment through this port. Yes, you can also use a mobile power bank to charge your laptop.

Size: Its size is very small, so the company gets more benefits in manufacturing thin laptops and can work on one side.

Multipurpose: The most important thing about these USB C ports is that you can connect an external monitor, charge, and transfer data from one device to another at high speed (up to 10GB/s).

Final Words

After all, I want to say that if you’re going to buy a new electronic product such as a laptop, computer, or any device, please check if it is compatible with Thunderbolt.

If you do not check this item, you will face a very slow data transfer speed or the problem of connecting peripheral devices that you don’t want to do.
