The USB 4 Version 2.0 specification arrives with twice the speed width and improvements in the physical architecture to reach 80 Gbps.
The USB Promoter Group has announced the USB 2.0 specification 4, an important update of which we will know all the details in November but, in the meantime, we can open our mouths with the key data. The main feature is that it double the speed compared to USB 4which was 40 Gbps, now reaching no less than 80Gbps. For this, physical layers have been added to the architecture of the connectors and, of course, the existing one in USB 4 1.0 has been used, so that the new specification will be backwards compatible up to and including USB 2.0.
The specification USB 4 2.0 will make better use of bandwidth available in USB 3.2, DisplayPort and PCIe connections, so expect an improvement when using this type of cable even if the connection is not USB 4. Also USB power delivery protocols updated (USB Power Delivery) and USB-C, although these details will arrive on November 1, 2, 15 and 16 at the USB Developer Days 2022 event.
In this way, it seems that the USB 4 nomenclature It advances like that of USB 3, existing Gen1 (Version 1) and Gen2 (Version 2). It should be remembered that the commercial nomenclature differs quite a bit from the technical one, which you can review in this article.

At the age of 15 I started overclocking my PC to squeeze out every extra FPS I could in games and scratch a few milliseconds in SuperPi, while posting tirelessly about hardware on the Geeknetic forum as a user and reader. Surely they were so tired of continually reading me in the forum that I became part of the editorial team, in which I continue to report on the latest technology. Astrophysics and PC gaming are the hobbies that, after hardware, cover most of my free time.
