Now you might think that we’re only just getting used to USB 3.2, or Type C, but apparently devices using USB4 will start to become available next year. USB4 will fit the same port as the Type-C, which is great because you don’t have to worry about which way around your cord plugs in, and it’s small enough for little devices like phones. USB4 cables will be compatible with these ‘old’ ports, which we have all been thinking of as new until today. USB4 is based on Intel’s great Thunderbolt technology, which they started out by keeping proprietary but which they have since decided to share with the world.
The main reason for the drive to improve lead technology is speed. The very best cable available now, the USB 3.2, will allow you to transfer data at a rate of up to 20 Gigabits per second, but the new USB4 will shift data at up to 40 Gigabits per second, fully doubling the speed. It will also provide much faster charging of devices. The speeds we’re talking about here would allow you to run two 4K monitors at once, for example. This upgrade will essentially remove the data bottleneck that has been cables until now; the technology that this will support will be rather exciting.
