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. There are certain minimum specifications that Thunderbolt 4 is guaranteed to meet that makes it the most comprehensive solution available from USB-C connectors.

Thunderbolt 4 is a step up from USB4 and Thunderbolt 3 technologies. 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.

The maximum speed of 40Gb/s remains the same for Thunderbolt 4 and Thunderbolt 3. However, the minimum PC and accessory requirements have increased for Thunderbolt 4 – including the requirement of Intel certification for all Thunderbolt 4 products.

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. A good example is the requirement of Thunderbolt 4 cables up to 2 meters in length to support the full 40Gb/s speed.

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).

Thunderbolt 4 simplifies your computer ports where one Thunderbolt 4 port can replace up to 12 other ports. It can support dual 4K monitors or a single 6K monitor at 60Hz. The port makes it easy to connect to multiple protocols including DisplayPort and PCI Express while supporting Intel VT-d based DMA protection. All these combined with 40Gb/s speed ensures a better user experience with reliable connectivity and maximum performance.

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.

Use Multiple Displays with Thunderbolt 4 / USB-C 4

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.

Thunderbolt 4 promises comfortable connectivity to two 4K displays or one 6K display at 60Hz resolution. With a dock that has four Thunderbolt 4 ports, you can connect the external displays and set up your perfect workspace.

You have to take note of the approximate video bandwidth requirements of the different display resolutions to arrive at the best combination of displays for you.

For a 10-bit color display at 60Hz, accounting for Thunderbolt 4 transfer efficiencies for video data, the approximate bandwidth requirements are mentioned below.

2.5K Display: ~8 Gbps (2560 X 1600~= 4.1MP)
4K Display: ~14 to 15 Gbps (3840 X 2160 ~= 8.3MP or 4096 X 2160 ~= 8.85MP)
5K Display: ~22 Gbps (5120 X 2880 ~= 14.7MP)
6K Display: ~31 Gbps (6016 X 3384 ~= 20.3MP)

A dual 4K display will consume as much as 32 Gbps that leaves only 8 Gbps for regular data. Meanwhile, a 6K display will consume about 30 Gbps leaving 10 Gbps for regular data.

Thunderbolt 4 / USB-C Hub

If you want a portable connectivity expander for your Thunderbolt 4 enabled computer, then USB-C hubs can be the best addition to meet your needs. These hubs will draw power from your computer and their small size makes them easy to carry around. In addition to connecting to external displays, you can connect to external hard drives, a keyboard, and a mouse with these hubs.

USB-C hubs can also have SD and microSD card readers, HDMI, DisplayPort, and USB-A ports for being compatible with your other peripherals.

You can buy USB-C hubs with multiple Thunderbolt 4 ports to connect to the best Thunderbolt 4 monitor for your workspace. This is an essential accessory if you’re looking for an easy and portable extended connectivity option for your computer.
