USB 4 Specifications Announced Days After USB 3.2

Supports up to 40Gbps transfer speeds

Days after the new USB 3.2 standard was announced, the USB Implementers Forum (USB-IF) announced the USB 4 standard - which supports up to double of what the USB 3.2’s transfer speed. USB 3.2 was announced with up to 20Gbps and USB 4, up to a staggering 40Gbps.

Both USB 3.2 and USB 4 only works with USB-C, and as read in the press statement: “As the USB Type-C connector has evolved into the role as the external display port of many host products, the USB 4 specification provides the host the ability to optimally scale allocations for display data flow.”

While that’s all fine and dandy, 2019 flagship phone running on the Snapdragon 855 can only support up to 10Gbps transfer speeds, so they won’t be fully utilising even the USB 3.2 - A speed that is rarely needed with smartphone users.

 

It was also claimed by Intel that USB 4 will “increase compatibility among USB Type-C connector-based products, simplifying how people connect their devices.” While not completely needed in smartphone, this sort of tech is definitely viable in more powerful laptops and desktops.

The press statement also said that the full list of specifications will be published during USB Developer Days 2019 in the second half of 2019 “covering the USB4 specification and the latest for USB Type-C, USB Power Delivery, and other exciting topics.”
