no not again are you telling me that
there's now a second version of usb4 which already carried over the super
confusing naming scheme from USB 3.
well I guess here's another tech Wiki where we explain why it's not just
called usb5 or SD USB 4.1 or something so what do you
need to know unsurprisingly it's fast like really fast usb4 version 2.0 tops
out at a whopping 80 gigabits per second twice as fast as the existing USB 4 gen
3x2 and yes I'm getting a headache just
saying that that works out to just under 10 gigabytes per second so it's actually
faster than that PCI Express 4.0 X4
connection the nice SSD inside your computer is probably using and that's
wild because the USB implementers form hasn't yet published the full
specification there aren't many details at this time as to how they pulled off
this speed increase other than a vague statement about a new physical layer
architecture but we did find out from our friends over at Cal digit that the
main way they did this was by switching over to a signaling scheme called Pam no
not the cooking spray Pam basically means that instead of two possible
digital signaling levels to represent a 0 or A1 there are four signaling levels
that can represent zero zero zero one one zero or one one so you're moving
twice as much data at the same time there still will be dedicated active 80
gigabit rated cables which USB if confirmed are aimed at folks who need to
have longer cable runs but to reiterate you do not need a new cable to get the
higher speed over shorter distances pretty good this is great news for folks
that need to move lots of data around quickly although this might make you
think of people that shoot lots of high-res video the use cases potentially
include everything from multi-function docs to external GPU enclosures to high
performance displays it's no coincidence that USB 4 version 2
has the same maximum bandwidth as the latest version of DisplayPort 80
gigabits per second is enough to drive three 4K screens at 90 frames per second
with HDR support So as displays that offer High resolutions and HDR become
more common along with scent and games that can take advantage of them this
latest USB revision could get us closer to a one cable for everything future
instead of having to use separate HDMI and DisplayPort connectors and even more
impressive is that instead of running USB 4 V2
in the default mode which provides 80 gigabits upstream and 80 Downstream you
can instead run 120 down and 40 up which
could allow even higher resolutions and refresh rates but this isn't yet an
official part of the spec so it remains to be seen how widespread support for it
will actually be and not only does usb4 version 2 carry DisplayPort 2.0 signals
it also continues to support PCI Express and Thunderbolt that's how it can
support an external GPU but how soon will it actually be available we'll tell
you right after we thank team group for sponsoring this video team group is
currently giving away an exclusive set of their 32 Gigabyte Delta RGB 64
megahertz ddr5 RAM sounds tasty it has
support for Intel's XMP 3.0 for Ultra fast speeds in a single click and it
features 120 degrees of ultra wide RGB lighting with a clean geometric
silhouette team group will also be releasing a new Gen 5 SSD and an all new
AIO that liquid cooler that will cool your CPU and your m.2 SSD at

it's not exactly a big secret that the theoretical maximums of USB and other
high-speed interconnects have so far outpaced how the vast majority of people
use them keyboards and mice require very little bandwidth flash drives often
aren't used for much more than a few photos and documents and most of us
these days only use the USB ports on phones for charging given this it
shouldn't be surprising that the USB promoter group has come out and said
that the update is being released mostly for the benefit of developers at the
moment even if it does seem useful to run several high bandwidth devices off a
single port it's hard to find mainstream laptops that even have any usb4 version
1 ports as you mostly have to look at the higher end of the laptop Market if
you want to be on the bleeding edge so usb4 V2
won't exactly be consumer ready for the holiday season and there isn't yet a
timetable for when you'll be able to Fork over a ton of money for a computer
and or a display that actually supports it think of this more as a small step
towards a more simple future without a boatload of connectors though there are
absolutely no signs that the usbif is interested in a future where the names
of our USB connectors are equally simple
you know what is simple though me thanking you for watching this video hey
