Japanese PC peripheral specialist ELECOM has announced the launch of USB4 Gen2 cabling. It is the first certified for the new standard that will be launched in mid-December and will make it possible data transfers up to 80 Gbps.
In addition to an impressive speed, which will double that achieved by the initial version of USB4, the improvement of the standard will allow other extremely interesting advantages, such as compatibility with USB Power Delivery EPR that will allow us a practically universal recharge of peripherals, mobile or laptops (USB Type-C connectors) and that will support beastly power supplies of up to 240 W (48 V/5 A).
Another great advantage of this standard is the support for the DisplayPort alternative way with which we can connect computer equipment with display screens at very high native resolutions, up to 8K (7680 x 4320 pixels) with a refresh rate of 60 Hz.
USB-IF, the standard’s governing body, is expected to formally launch USB4 Gen2 next December. A typical USB4 2.0 host controller will require at least one PCI-Express 5.0 x4 system bus connection to achieve the maximum bandwidth of the standard. Of course, the latest generation motherboards will support it.
USB4 Gen2, underway
You already know that this USB (Universal Serial Bus) is the most popular port on the market for connecting peripherals and devices. The latest version of the standard, USB4, was approved in 2019, but it was not until this year that it began to be generally deployed in new generations of laptops, mobile phones or storage devices. Its differences and improvements compared to USB 3 are striking.
Although the general standard already stood out in performance by doubling the base bandwidth up to 40 Gbps and also for being the first to converged with Intel’s Thunderboltonce he opened the specifications and shared them with the USB Promoter Group so that manufacturers could use it without paying royalties, more recently the second generation that concerns us in this entry was approved.
USB4 2.0 goes one step further, in this case in performance, as it doubles data transfer performance again up to 80 Gbps equaling the fastest existing to date, Intel’s Thunderbolt 4, and with the improvements outlined in all sections. The new standard will be retrocompatible with the initial version of USB4 and also with previous versions such as USB 3.2 and USB 2.0, although we will need specific hardware and cabling to obtain maximum performance.
