USB4 Is Coming: Here Is The Speed

USB 3.2, the most recent, shipping, standard sees a maximum transfer speed of 40Gb per second. USB4 will double that. Said another way, 80Gbps is equal to moving 10,000MB in one second. Said another way, that’s about 10GBs in one second.

Keep in mind, this is all theoretical, maxium speed. Real world applications will not get to this point. Never has, never will.

USB4 is built on Intel’s Thunderbolt technology. You know, the technology Apple tried to force everone to use back in 2012. The big change for USB is the interface. The Thunderbolt licensing setup is expensive and thus, we never saw low priced accessories to accommodate the technology. This is why Intel was always so interested in getting Thunderbolt to be the backbone for USB. It would gain in both speed and reduced price.

USB4 is also backwards compatible with USB 3.2, USB 2.0 and Thunderbolt 3. Since the new standard merges both USB-C and Thunderbolt, we should start to see decreasing accessory price points that utilize faster speeds as USB4 gains popularity.

USB4 device manufacturers must also include USB Power Delivery technology, which regulates device charging. PD can quickly charge your phone or gaming laptop, sending the optimal amount of wattage for each device to charge quickly without damage.

Expect to see the first USB4 products hit the market as early as mid-2020. This post was made because the finalized specification was released by the governing body, USB-IF.
