USB4 2.0 has arrived: immoderate speed, up to 120 Gbit / s!

While at the beginning of the month Europe has approved universal USB-C charger, today we are happy to give you equally succulent news. The standard USB4 has just been announced, making data transfer speeds, as well as device charging, even faster. The figures speak for themselves: numbers beyond imagination! Let's go see the details.

USB4 2.0 is the name of the new standard, so to speak, which will allow charging and data transmission at a speed never seen before.

In Press release disclosed by USB-IF, the upgrade of the standard from the basic version to version 2.0 is announced. Despite the identical appearance of the USB Type-C connectors and inputs, a single standard supports different data transfer rates. For example, USB 2.0 can deliver speeds up to 0,48 Gb / s and current USB4 reaches up to 40 Gb / s. The developers of the standard went further and shared the details of the USB4 2.0 standard, which it can "Overclock" the speed up to 120 Gb / s.

We first heard about USB4 2.0 in September. The developers announced a data transfer rate of 80 Gb / s in two directions (40 Gb / s per line, two lines in each direction). However, on October 19, the specs were updated: USB4 2.0 will support up to 120 Gb / s across three lanes. To do this, the interface can be configured asymmetrically: maintain 80 Gbps in one direction on two lanes and offer three 40 Gbps lanes in the other direction.

With this configuration, the device will use the 80 Gbps link by default, using an additional line if necessary. For example, when streaming 4K video to multiple monitors. The developers note that the standard will retain backward compatibility with USB and a special cable will be required to use USB4 2.0 (but the connector will remain the same).
