The advent of USB 4 has revolutionized the way we transfer data and connect devices.
In this article, we will delve into the realm of USB 4, exploring its definition, working mechanism, advantages, differences from USB-C and Thunderbolt, available devices, and offer some final thoughts on this groundbreaking technology.
Read on to find out everything you need to know about this mysterious USB 4!
USB 4 is a high-speed serial bus standard that was introduced by the USB Implementers Forum (USB-IF).
Is a high-speed data transfer and power delivery protocol that enhances the connectivity experience.
It is the successor to USB 3.2 and was officially announced in 2019.
USB 4 is based on Intel's Thunderbolt 3 technology and incorporates several advancements over previous USB versions.
It builds upon the foundation of its predecessors while introducing several advancements to cater to the increasing demands of modern digital enthusiasts.
USB 4 operates as a high-speed serial bus that uses the USB-C connector for physical connectivity.
It relies on a combination of technologies, including Intel's Thunderbolt 3 protocol, to achieve its enhanced capabilities.
Here's a more detailed explanation of how USB 4 works:
By combining these features and technologies, USB 4 provides high-speed data transfer, versatile connectivity options, and improved power delivery capabilities, making it a robust and flexible solution for connecting various devices and peripherals.
USB technology has evolved significantly since its inception. USB 1.0 started with a modest transfer speed of 12 Mbps, which gradually increased to 480 Mbps with USB 2.0. USB 3.0 brought a major leap with transfer speeds up to 5 Gbps, which was later refined to 10 Gbps with USB 3.1. Now, USB 4 takes it even further with an impressive 40 Gbps transfer speed.
USB 4 supports daisy-chaining, allowing multiple devices to be connected in a series. It also enables the delivery of up to 100W of power, facilitating fast charging for compatible devices. Additionally, USB 4 ports can transmit video and audio signals, reducing the need for separate display and audio connectors.
USB 4 refers to the latest USB standard, while USB-C is a type of connector.
USB 4 can operate through a USB-C port, but not all USB-C ports support USB 4.
USB-C is a versatile connector that can support various protocols, including USB 4, USB 3.1, and Thunderbolt 3.
USB 4 incorporates Thunderbolt 3 technology, making it similar in terms of performance and capabilities.
However, Thunderbolt offers additional features such as higher power delivery and support for external GPUs.
The choice between USB 4 and Thunderbolt depends on the specific requirements of your devices.
USB 4 devices are gaining popularity, and manufacturers are embracing this technology. Some of them are listed below. But it's worth noting that you'll want to pay close attention to the product name before buying, as USB 4 products will often include USB 4 as a handy reminder.
