USB 4 specification has been announced

Thunderbolt is becoming USB 4?

Last week USB-IF formally announced USB 3.2 alongside a confusing new naming scheme. It looks like, USB 3.2 and its ultra-fast USB 3.2 Gen 2x2 variant is going to be short lived since USB-IF has announced the initial specification for USB 4.

The USB Promoter Group has revealed its USB 4 specification, which thanks to the contribution of Intel's Thunderbolt standard will offer 40Gbps of bandwidth. In other words, we are facing at a 2x improvement over USB 3.2 Gen 2x2. Thunderbolt 3 will become the next iteration of USB and it'll be fully compatibility with USB 3.2, USB 2.0 and Thunderbolt.

As you might know, Intel is going to integrate Thunderbolt 3.0 directly onto their processor with the upcoming Ice Lake architecture. In this way, Intel will be the first to support USB 4 standard and AMD might need a while before offer the same support. With just a single move Intel has ensured that their Thunderbolt standard will be adopted by every major manufacturer.

The USB 4 will use a Type-C connection rather similar to Thunderbolt 3. During this year, we'll be getting USB 3.2 2×2 Type-C cables with 20Gbps speeds and, in a couple of years, we'll start to see USB 4 cables with 40Gbps speeds.
