The USB port continues its unstoppable evolution in the form of increasingly faster versions and we can say that with the USB4 2.0 gave the bell, making it the fastest peripheral interface in history. Will we see HDMI 2.1 and DisplayPort swallowed up by the new version of Universal Serial Bus? What new features does the new version of the standard bring us?
Today, few devices support USB 4, so talking about version 2.0 may seem strange to us. Although this is normal in computer standards, because all follow regulations that must be written well before their implementation in hardware so that there are no compatibility problems when the various peripherals are released on the market and components that use it. .
What’s new with USB 4 2.0?
Well it seems to start a 80 Gbps transfer rate or it’s the same 10GB/2. Ahora pensadlo bien, vuestras unidades SSD M.2 con interface PCI Express transmiten a 7 GB/s, lo que este puerto hará possible tener unidades de este type de forma completamente externale con un rendimiento casi idéntico a las internal unidades de hoy en day. Of course, we will have to wait a bit for that. Since then, only the official announcement of USB 4 2.0 has been made, but the specifications for its implementation have not yet been released.
The only thing we know is that Will be backwards compatible with USB 4 version 1.0 and versions 3.2 and 2.0, as well as Thunderbolt 3
The end of HDMI and DisplayPort?
Let’s not forget that HDMI 2.1 operates at 48 Gbps of bandwidth, just over half of what USB 4 2.0 supports. Today this may seem like an incredible bandwidth, but the reality is that, for example, if we want to enjoy 4K content at a refresh rate of 120 Hz and at the maximum color resolution, we have to losing image quality due to DSC or Display Data Compression. This new version of the standard therefore has many numbers to become the future cable for video interfaces. Especially due to the fact that it will easily allow all sorts of peripherals to communicate through the USB-C port.
Let’s not forget that the USB Alt DP function used for video transmission is nothing more than an implementation of DisplayPort. In any case, the new version will allow the same port to be used for DP 2.0 at the same time as for data transfer with the speed of the first USB 4. This is why we believe that many manufacturers, especially those of cards mothers, are going to eliminate conventional video outputs to use the future port for this.
