Intel announces USB 4 standard

USB 4 Debuts With Twice the Throughput and Thunderbolt 3 Support

Inside of the announcement came news that USB 4 would be compatible with Thunderbolt 3 (as well as USB 3.2 and USB 2.0). Intel plans to integrate support for Thunderbolt 3 and USB4 natively into upcoming products. Today Thunderbolt 3 was released to the USB Promoter Group, who promptly undid the insanity that the USB-IF released upon us last week by promptly announcing it will be the basis of USB 4. "The USB4 solution specifically tailors bus operation to further enhance this experience by optimizing the blend of data and display over a single connection and enabling the further doubling of performance." . USB4 is set to feature Thunderbolt 3 compatibility as well. As a result, maximum speeds for USB4 double to 40 Gbps using existing certified cables, matching the speeds offered by Thunderbolt 3. So this year, we'll be getting USB 3.2 2×2 Type-C cables with 20Gbps speeds and dual-lane bandwidth, in a year or two, we'll start to see USB4 roll out with Type-C and 40Gbps speeds.

Because Thunderbolt 3's technology is now open and royalty-free, the devices that would benefit from it will be less expensive and more likely to exist in the first place. Thunderbolt 3 also provides up to 100W of power for system charging and 15W for bus-powered devices. USB 4 will be compatible with USB 2.0 and 3.2, too. With that said, nobody has seen a USB4 port yet so we don't know if it will differ from the current USB-C standard. Of course, it is much more open than Thunderbolt 3, because the use of Thunderbolt 3 must be strictly certified by Intel (only 463 models so far).

While Thunderbolt 3 offers a range of benefits, and is in use in a broad range of hardware - from docks and displays, to storage and external GPUs - it's interesting to note there are now only a little over 450 certified devices in the market.

Huawei P30 and P30 Pro Renders Leaked, Revealing Astonishing Gradient Color Schemes
Firstly there's a much smaller teardrop notch at the top of the phone which is much less intrusive than on the current P20 Pro . The only other thing that is revealed in the image are some new colours with a striking blue and more subtle grey both on show.

"Releasing the Thunderbolt protocol specification is a significant milestone for making today's simplest and most versatile port available to everyone". That's finally happening, with the technology being integrated into USB 4. The USB firmware on the devices you are connecting will be able to split the data you are transferring into two individual streams on the device sending it and put it all back together into a stream of data that the device receiving it can read correctly.

In recent years, the USB Implementers Forum (USB-IF) has developed this freakish habit of releasing specification updates that are often tremendous steps forward but are obscured by confusing, misleading, or downright awful naming.

The USB 4 standard will be finalized in mid-2019. "By collaborating with the USB Promoter Group, we're opening the doors for innovation across a wide range of devices and increasing compatibility to deliver better experiences to consumers".
