1. USB4 Overview
USB4 is the latest version of the Universal Serial Bus (USB) standard developed by the USB Implementers Forum (USB-IF). It is designed to enable faster, more efficient, and more powerful connections. USB4 is compatible with Thunderbolt 3, DisplayPort, and USB 2.0, 3.2, and 4, making it the most comprehensive USB standard to date.
2. USB4 speed upgrade
The biggest highlight of USB4 is that its speed is upgraded to 80Gbps, which is twice as fast as the previous generation USB standard. The upgrade comes courtesy of Intel's Thunderbolt 4 technology, which is what USB4 is built on. Thunderbolt 4 uses a 40Gbps link, and USB4 achieves a maximum transfer speed of 80Gbps by combining this link. Compared to USB 3.2's top speed of 20Gbps, USB4 is a significant speed increase.
3. Comparison between USB4 and previous versions
Looking back at the development history of USB, we can see that USB4 is a huge leap in speed. USB 1.0 was released in 1996 with a maximum speed of 12Mbps; USB 2.0 was released in 2000 with a maximum speed of 480Mbps; USB 3.0 was released in 2008 with a maximum speed of 5Gbps; and USB 3.2 was released in 2017 with a maximum speed of 20Gbps. USB4's 80Gbps speed is four times faster than USB 3.2 and sixteen times faster than USB 2.0, and this speed increase will greatly improve the experience of high-bandwidth applications such as video editing and gaming.
4. Reasons why USB4 becomes a game-changer in the field of high-speed connections
There are several reasons why USB4 is a game-changer in high-speed connectivity: first, it can transfer large files, such as 4K videos, in seconds, allowing content creators to transfer their works more easily and quickly; second, It can transmit high-quality video and audio without buffering or delay, improving the quality of video conferencing and online gaming; finally, USB4's compatibility with multiple USB standards makes it versatile and future-proof. As technology advances, USB4 will continue to keep pace and become a worthwhile investment.
5. Conclusion
In short, USB4's 80Gbps speed upgrade marks a new-era of high-speed connections. Its speed and versatility will greatly improve the experience of large file transfers, high-quality video and audio streaming, and high-bandwidth applications. At the same time, USB4's compatibility with multiple USB standards also makes it future-proof. As we become more and more reliant on technology, the upgrade to USB4 is undoubtedly a timely advancement.
