USB4 Version 2.0 to Offer 80Gb/s Transfer Speeds

[MacRumors]

USB4 Version 2.0 is in the works and when launched, it will allow for double the speeds of the current USB4 specification with existing USB-C cables. It will support up to 80Gb/s operation with both 40Gb/s USB-C passive cables and newly defined 80Gb/s active cables.

The updated specification was announced today by the USB Promoter Group, comprising Apple, Microsoft, Intel, HP, STM, and others. USB Type-C and USB Power Delivery specifications will be updated to enable the higher level of data performance, and updates are being made to enable higher performance USB 3.2, DisplayPort, and PCIe data tunneling to better take advantage of the bandwidth improvement.

As outlined in the announcement, the updated USB4 specification will include the following:

• Up to 80 Gbps operation, based on a new physical layer architecture, using existing 40 Gbps USB Type-C passive cables and newly-defined 80 Gbps USB Type-C active cables.
• Updates to data and display protocols to better use the increase in available bandwidth.
• USB data architecture updates now enable USB 3.2 data tunneling to exceed 20 Gbps.
• Updated to align with the latest versions of the DisplayPort and PCIe specifications.
• Backward compatibility with USB4 Version 1.0, USB 3.2, USB 2.0 and Thunderbolt 3.

The USB Promoter Group says that the updated specifications are expected to be published ahead of the USB DevDays developer events that are planned for November. The update is targeting developers at this time, with branding and marketing guidelines to be updated at a future date to include USB 80Gb/s for identifying certified products and cables.

That’s incredible

This is definitely going to make a huge difference on future Macs that will have USB 4 Version 2.0 with regards to transferring video files

Apple has definitely staked a huge portion of their future business on the Mac lineup and an improvement as immense as this has massive potential to be a game changer for dominating the computing industry in the years going forward

Definitely am excited to see Apple continuing to innovate and improve upon products that are already unbelievable

Read this last year or maybe year before.

I’m saving for the 16K monitor.

 

[tomtad]

USB4 Version 2.0. I'm sorry, what!?

 

[ruka.snow]

Could just call it USB 5 and move away from this daft situation we are in with multiple things being called the same thing.

 

[UltimateSyn]

USB4 Version 2.0. I'm sorry, what!?

And the USB naming conventions continue to get even more confusing…

 

[0112862]

why usb 4 2.0. they are starting it again 😭.
USB
USB 2.0
and USB 3.0. Good old time.

 

[UltimateSyn]

Just wait for USB4 Version 2.1 Mk III

 

[GianL]

"PCIe data tunneling"
I wonder if we will ever be able to use this for an eGPU enclosure with Apple Silicon

 

[citysnaps]

I don't understand why people struggle with naming conventions.

It's not that difficult. Or maybe it's just needing something to complain about for the day?

That said, I'm looking forward to the speed increase using passive cables.

 

[doboy]

Stop just doubling the speed. We need to at least quadruple the speed with each iteration Maybe that's USB 4.2 gen 2x2, haha.

 

[Ashbash75]

I'm waiting for USB4 2.0 PRO MAX GTI V12

 

[gaximus]

Shouldn't USB4 version 2, just be USB5. Unrelated I'm about to turn 35 version 4.

 

[GubbyMan]

They're probably going to rename this USB4.1 Gen 4x2 Version 2 next year when they introduce USB4.1 Gen 6x2 Version 2.1.

 

[Bokito]

Could just call it USB 5 and move away from this daft situation we are in with multiple things being called the same thing.

That’s just to confuse you so you buy the wrong thing first so you have to spend money twice.

How will we differentiate between passive and active cables? Also, why USB 4 version 2.0, what's wrong with calling it 4.1 or 4.5 if they plan an USB 5 soon afterwards?

 

[tomtad]

I don't understand why people struggle with naming conventions.

It's not that difficult. Or maybe it's just needing something to complain about for the day?

That said, I'm looking forward to the speed increase using passive cables.

It's the second version of the forth version or something like that

Because is a way for companies that make USB accessories to screw you, like USB4 fastest high speed cable (small lettering "but with speeds of an USB4 version 1").

Data transfer is getting to be so quick the files will end up in yesterday.

 

[MallardDuck]

Love the USB-C connector, but trying to figure out what a cable or device actually supports has become a nightmare. 3.1, 3.2, Thunderbolt 3, Thunderbolt 4, power only, power and data, active, passive...once a cable hits the rats nest, how on earth are we supposed to know? Let alone the devices themselves.

 

[falkon-engine]

Waiting on an announcement from Intel and Apple on thunderbolt 5. Thunderbolt's minimum feature set tends to be higher than USB's minimum feature set. I wonder if new TB5 controllers are coming to market soon... with support for USB4 v2 and some other goodies as well?

USB 4.0 version 2: Pro Max Rose Gold Edition

 

[guzhogi]

Stop just doubling the speed. We need to at least quadruple the speed with each iteration Maybe that's USB 4.2 gen 2x2, haha.

Should multiply by 10 like Ethernet: 10 Mb > 100 Mb > 1 Gb (1000 Mb) > 10 Gb

Yeah, the nefarious "companies" out to screw their customers. For sure that's a sound business plan for customer retention and growth.

Pro tip: Read, and most importantly, understand the specs before you buy a cable. Easy.

 

[masterleep]

Naturally the required cables look exactly like all the other cables so you never know what's going to work.
