With a dock that has four Thunderbolt 4 ports, you can connect the external displays and set up your perfect workspace. Thunderbolt 4 promises comfortable connectivity to two 4K displays or one 6K display at 60Hz resolution. Since Thunderbolt 4 bandwidth of 40Gb/s is per bus and not per port, you will need at least two Thunderbolt 4 busses on your computer for full performance with high-resolution displays and a high-performance SSD. If you’re looking for a clutter-free and highly productive desktop setup, you can choose from the best Thunderbolt 4 monitors to connect to your dock to unleash the power of a smarter workspace. All these combined with 40Gb/s speed ensures a better user experience with reliable connectivity and maximum performance. The port makes it easy to connect to multiple protocols including DisplayPort and PCI Express while supporting Intel VT-d based DMA protection. It can support dual 4K monitors or a single 6K monitor at 60Hz. Thunderbolt 4 simplifies your computer ports where one Thunderbolt 4 port can replace up to 12 other ports. Thunderbolt 4 promises docks with four Thunderbolt ports for improved connectivity, PC charging on at least one computer port (applicable for notebooks that require only less than 100W to charge), required wake from sleep when the computer is connected to a Thunderbolt port, improved minimum PC video requirements (two 4K displays), and improved minimum PC data requirements (PCIe 32 Gb/s). A good example is the requirement of Thunderbolt 4 cables up to 2 meters in length to support the full 40Gb/s speed. This means that when you’re buying a Thunderbolt 4 product, you’re actually assured of the technical specifications and promised capabilities of the product. However, the minimum PC and accessory requirements have increased for Thunderbolt 4 – including the requirement of Intel certification for all Thunderbolt 4 products. The maximum speed of 40Gb/s remains the same for Thunderbolt 4 and Thunderbolt 3. While it may be a little confusing to differentiate these technologies, Intel has created a chart to give a better understanding of the capabilities of Thunderbolt 4. Thunderbolt 4 is a step up from USB4 and Thunderbolt 3 technologies.

There are certain minimum specifications that Thunderbolt 4 is guaranteed to meet that makes it the most comprehensive solution available from USB-C connectors. Announced at the CES 2020, Thunderbolt 4 is the next-generation technology with the capability to transfer data, carry video output to display, and power your PC and Mac M1 using a single USB-C cable.
