00:00:00.079 --> 00:00:06.359
no not again are you telling me that

00:00:04.200 --> 00:00:11.280
there's now a second version of usb4 which already carried over the super

00:00:08.099 --> 00:00:13.080
confusing naming scheme from USB 3.

00:00:11.280 --> 00:00:15.800
well I guess here's another tech Wiki where we explain why it's not just

00:00:15.059 --> 00:00:24.539
called usb5 or SD USB 4.1 or something so what do you

00:00:21.660 --> 00:00:30.779
need to know unsurprisingly it's fast like really fast usb4 version 2.0 tops

00:00:28.500 --> 00:00:37.079
out at a whopping 80 gigabits per second twice as fast as the existing USB 4 gen

00:00:33.899 --> 00:00:39.480
3x2 and yes I'm getting a headache just

00:00:37.079 --> 00:00:45.420
saying that that works out to just under 10 gigabytes per second so it's actually

00:00:42.059 --> 00:00:47.640
faster than that PCI Express 4.0 X4

00:00:45.420 --> 00:00:51.719
connection the nice SSD inside your computer is probably using and that's

00:00:49.140 --> 00:00:55.739
wild because the USB implementers form hasn't yet published the full

00:00:53.340 --> 00:01:00.120
specification there aren't many details at this time as to how they pulled off

00:00:57.719 --> 00:01:04.260
this speed increase other than a vague statement about a new physical layer

00:01:01.980 --> 00:01:08.220
architecture but we did find out from our friends over at Cal digit that the

00:01:06.299 --> 00:01:14.100
main way they did this was by switching over to a signaling scheme called Pam no

00:01:11.820 --> 00:01:17.700
not the cooking spray Pam basically means that instead of two possible

00:01:15.720 --> 00:01:23.220
digital signaling levels to represent a 0 or A1 there are four signaling levels

00:01:21.000 --> 00:01:28.320
that can represent zero zero zero one one zero or one one so you're moving

00:01:26.220 --> 00:01:33.299
twice as much data at the same time there still will be dedicated active 80

00:01:31.080 --> 00:01:38.280
gigabit rated cables which USB if confirmed are aimed at folks who need to

00:01:35.460 --> 00:01:42.840
have longer cable runs but to reiterate you do not need a new cable to get the

00:01:41.100 --> 00:01:47.220
higher speed over shorter distances pretty good this is great news for folks

00:01:45.840 --> 00:01:50.399
that need to move lots of data around quickly although this might make you

00:01:49.020 --> 00:01:54.479
think of people that shoot lots of high-res video the use cases potentially

00:01:52.740 --> 00:01:59.340
include everything from multi-function docs to external GPU enclosures to high

00:01:57.180 --> 00:02:04.799
performance displays it's no coincidence that USB 4 version 2

00:02:01.939 --> 00:02:08.160
has the same maximum bandwidth as the latest version of DisplayPort 80

00:02:06.479 --> 00:02:13.920
gigabits per second is enough to drive three 4K screens at 90 frames per second

00:02:10.979 --> 00:02:18.540
with HDR support So as displays that offer High resolutions and HDR become

00:02:16.319 --> 00:02:22.440
more common along with scent and games that can take advantage of them this

00:02:20.400 --> 00:02:28.260
latest USB revision could get us closer to a one cable for everything future

00:02:25.280 --> 00:02:32.340
instead of having to use separate HDMI and DisplayPort connectors and even more

00:02:30.720 --> 00:02:37.739
impressive is that instead of running USB 4 V2

00:02:35.060 --> 00:02:44.879
in the default mode which provides 80 gigabits upstream and 80 Downstream you

00:02:40.860 --> 00:02:46.920
can instead run 120 down and 40 up which

00:02:44.879 --> 00:02:51.180
could allow even higher resolutions and refresh rates but this isn't yet an

00:02:49.260 --> 00:02:56.160
official part of the spec so it remains to be seen how widespread support for it

00:02:53.340 --> 00:03:02.220
will actually be and not only does usb4 version 2 carry DisplayPort 2.0 signals

00:02:59.879 --> 00:03:06.540
it also continues to support PCI Express and Thunderbolt that's how it can

00:03:04.319 --> 00:03:10.319
support an external GPU but how soon will it actually be available we'll tell

00:03:08.580 --> 00:03:14.159
you right after we thank team group for sponsoring this video team group is

00:03:12.000 --> 00:03:20.340
currently giving away an exclusive set of their 32 Gigabyte Delta RGB 64

00:03:16.860 --> 00:03:22.920
megahertz ddr5 RAM sounds tasty it has

00:03:20.340 --> 00:03:27.599
support for Intel's XMP 3.0 for Ultra fast speeds in a single click and it

00:03:24.900 --> 00:03:31.440
features 120 degrees of ultra wide RGB lighting with a clean geometric

00:03:29.400 --> 00:03:35.940
silhouette team group will also be releasing a new Gen 5 SSD and an all new

00:03:34.080 --> 00:03:42.120
AIO that liquid cooler that will cool your CPU and your m.2 SSD at

00:03:40.319 --> 00:03:47.280
learn more about the giveaway and their Delta RGB ddr5 RAM at the link below

00:03:44.819 --> 00:03:51.599
it's not exactly a big secret that the theoretical maximums of USB and other

00:03:49.620 --> 00:03:56.340
high-speed interconnects have so far outpaced how the vast majority of people

00:03:53.879 --> 00:03:59.760
use them keyboards and mice require very little bandwidth flash drives often

00:03:58.379 --> 00:04:03.299
aren't used for much more than a few photos and documents and most of us

00:04:01.440 --> 00:04:07.319
these days only use the USB ports on phones for charging given this it

00:04:05.700 --> 00:04:11.400
shouldn't be surprising that the USB promoter group has come out and said

00:04:09.239 --> 00:04:15.659
that the update is being released mostly for the benefit of developers at the

00:04:13.620 --> 00:04:20.220
moment even if it does seem useful to run several high bandwidth devices off a

00:04:17.940 --> 00:04:25.020
single port it's hard to find mainstream laptops that even have any usb4 version

00:04:22.680 --> 00:04:28.860
1 ports as you mostly have to look at the higher end of the laptop Market if

00:04:26.880 --> 00:04:34.020
you want to be on the bleeding edge so usb4 V2

00:04:31.680 --> 00:04:37.440
won't exactly be consumer ready for the holiday season and there isn't yet a

00:04:36.060 --> 00:04:42.120
timetable for when you'll be able to Fork over a ton of money for a computer

00:04:39.300 --> 00:04:46.680
and or a display that actually supports it think of this more as a small step

00:04:44.100 --> 00:04:51.300
towards a more simple future without a boatload of connectors though there are

00:04:48.900 --> 00:04:57.440
absolutely no signs that the usbif is interested in a future where the names

00:04:52.740 --> 00:04:57.440
of our USB connectors are equally simple

00:04:57.540 --> 00:05:03.780
you know what is simple though me thanking you for watching this video hey
