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.

Oh man, these guys seriously have zero clue about branding (not that any confirmation was needed after the whole 3.0/1/2 thing..). Why not let the USB brand as it is, be recognized as being super quick rather than forcing a situation where 'USB is slow and this thing here is super quick'. I mean its like they dont believe their own protocol is allowed to evolve into anything quicker over time. Just leave it be and give it a new number hahah. I'm glad the Bluetooth icon isnt changing with every iteration..

Ok i just needed to get that out of my system. Really not that big of a deal i know but i dont understand this need to change things for the worse.

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.

Then by all means give me devices to take advantage of said higher speeds.. I mean seriously who is at the forefront of the USB scheme of things....?!?

This is really sad when things like this happen. Devices and their speeds aren't even up to snuff with the transportation protocol available now, but let's slap a newer faster one out into the wild...

I just want Zen 2 to drop and that way I can see if the PCI-E lanes and their configuration on the X570 motherboards are going to hinder that PCI-E 4.0.

Because that X4 "interconnect" shtuff from the chipset to the CPU sounds like a really big bottleneck of sorts if all the devices are talking over just that connection internally....

Might just have to wait for Epyc and or threadripper 3?!?

GPU and 4k tv, maybe 8k, with decent frame rate.

Good thing - amd is getting thunderbolt next year
