USB4 will support Thunderbolt and double the speed of USB 3.2

It was just last week when we heard that the 20Gbps USB 3.2 connectivity may show up on new devices later this year, but today, the USB Promoter Group is already talking about an even speedier USB4. At a Taipei event earlier today, the organization revealed that this next-gen spec will once again utilize dual channels to achieve 40Gbps speeds, even on existing 40Gbps-certified USB-C cables.

Soon: USB 8.0 will be able to fly to the moon

For now, I'm still using USB 2.0.

Speed-doubling USB4 is ready. Now we just have to wait for devices
If you've seen the newer USB-C ports on laptops and peripherals, you know what to expect in 2020

USB4 is done, the group developing the next version of the immensely successful USB connector technology said Tuesday. USB4 doubles speeds compared to today's fastest USB 3.2 by incorporating Intel's speedy Thunderbolt technology that you already see on high-end laptops and peripherals.
The USB Implementers Forum announced the completion of the technical specification Tuesday, a move that frees hardware and software engineers to get cracking building the actual products to support it.

Today's USB 3.2, which enables data transfer speeds up to 20 gigabits per second, is still something of a rarity; most of us have earlier versions of the technology that works at 5Gbps or 10Gbps. USB4 promises a speed boost to 40Gbps, helpful for things like using multiple external displays or fetching files from external hard drives.

Lol, you need rather fast hard drives to take advantage of that..

Thunderbolt is optional in USB4
USB-IF leaves it to device implementers whether to implement Thunderbolt
September 4, 2019

The USB Implementers Forum has published the USB4 specification, as promised, though with one disappointment: Thunderbolt support is optional, meaning that there may be confusion over which devices can support what protocol.

When the USB4 spec was announced, the revelation was that it would integrate the Thunderbolt 3 specification for display and data connectivity that Intel had developed. Intel said at the time that it would contribute the Thunderbolt specification to the USB Promoter Group, and a spokeswoman has confirmed that.
But the assumption that USB4 would always include Thunderbolt is, according to the specification, not always true. The published spec makes it clear: It’s up to USB4 device makers to support Thunderbolt.

“Regarding USB4 specification’s optional support for Thunderbolt 3, USB-IF anticipates PC vendors to broadly support Thunderbolt 3 compatibility in their USB4 solutions given Thunderbolt 3 compatibility is now included in the USB4 specification and therefore royalty free for formal adopters,” the USB-IF said in a statement.
Unfortunately, that’s little consolation when trying to make sense of the USB-C ports that are becoming increasingly common on the side of laptops. A one-size-fits-all USB-C connector sounds like a good thing, but hardware makers are going to need to indicate clearly the capability of each connector, or risk frustrating customers who simply can’t remember which port does what.

USB4: everything you need to know
September 7, 2019
https://www.techradar.com/news/usb4-everything-you-need-to-know

USB4 is a new standard of connectivity, which at the time of writing has just had its specification officially confirmed by the USB Implementers Forum (USB-IF), the tech standards non-profit which is guardian and cheerleader of all things USB (Universal Serial Bus).

So what are the specs, how fast is USB4, what else does it do, and what will it really mean for you going forward? In this article, we’re going to cover all the essentials you need to know about this latest USB standard.
USB4 moves things on from USB 3.2 Gen 2x2 in a big way, doubling speeds up again to 40Gbps – data transfer levels previously only available to those using Thunderbolt 3 technology, which the new USB standard is built on – but there’s more to this picture than just pure speed, as we’ll explore below.
