USB 4.0 Will Arrive In Late 2020

Yeah, you just got used to USB 3.0, 3.1 and recently 3.2 right? It has been a confusing mess with the renamed denominators alright. But basically, the USB Promoter Group is finalizing the specifications of the new standard USB 4.0, the first products are expected in 2020.

The USB 4.0 Spec is at revision 0.7 and the USB Promoter Group will finalize it in a month or so with some availability in 2020. Guess what? It is based on Intel's Thunderbolt 3 technology and that achieves per at up to 40Gbit/s.

So that would be doubling up on the current fastest standard at 20 Gbit/s (USB 3.2 2x2). The USB Promoter Group) finds the differences so big that they are considering to create a new USB logo for it. USB 4 would be backward compatible with existing devices with USB 3.2, USB 2.0 as well as Thunderbolt 3. The new standard also adapts support on protocols like display port over Thunderbolt 3.

Personally still not using USB3.0 to it's fullest...

I still have nothing that use 3.0 let alone 3.1, most mouses and keyboards use 2.0 maybe, and I pretty sure none of usb stick are 3.0 or atlest they dont act like they do

They should have gone for 10 x jump like the one from usb2 to USB3 and get it over with. Cos if it's only double, I guarantee there will be incremental updates that will just cause more confusion.

But hey, this is only a forum post, and it will not make the slightest difference in the end.

Thats impossible, you need PCie lanes for USB to be connected to the chipset or CPU, even 40gbps is already insane, 40gbps per port, now imagine normal hi-end mainstream system with 12 ports, how much PCIe gen 4 lanes youll need,im sure that they planing for this to be for PCIe Gen5

This is great news for Intel and Thunderbolt will be put to a broader use finally together with usb 4. Intel has found the way to monetize its Thunderbolt, which was very little adopted and little used ,because it was proprietary and expensive. Intel's strategy: "If you can't beat them, just join them and use them"
