00:00:00.240 --> 00:00:06.319
it is a great time for USBC not only is the iPhone finally getting it but

00:00:04.759 --> 00:00:11.920
there's a fast new version of Thunderbolt namely Thunderbolt 5 that

00:00:09.160 --> 00:00:16.320
uses the USBC connector it gives faster maximum data transfer than Thunderbolt 4

00:00:14.320 --> 00:00:21.080
but it turns out Thunderbolt 4 isn't even the current top dog the Thunderbolt

00:00:18.320 --> 00:00:26.480
5 is trying to beat instead that title belongs to USB 4v2 and confusingly

00:00:24.720 --> 00:00:31.320
Thunderbolt might not look all that different than USB 4v2 which it's based

00:00:28.880 --> 00:00:35.960
on at first glance in fact it has the same maximum data rate 80 gbits per

00:00:33.920 --> 00:00:41.760
second in each direction or an asymmetric mode that gives you 120 gbits

00:00:38.719 --> 00:00:44.559
one way and 40 the other so what exactly

00:00:41.760 --> 00:00:49.840
is the point of Thunderbolt 5 then well one is to provide a higher performance

00:00:46.399 --> 00:00:52.640
floor than what USB 4 V2 offers although

00:00:49.840 --> 00:00:57.600
both Thunderbolt 5 and USB 4 V2 can optionally handle 240 watts of charging

00:00:55.719 --> 00:01:02.559
there's no guarantee your ports can actually deliver anything close to that

00:01:00.000 --> 00:01:08.400
your ports just ain't ready Thunderbolt 5 though requires at least one computer

00:01:05.720 --> 00:01:12.840
port that can charge a PC needing up to 140 watts of power and 15 wats of power

00:01:10.960 --> 00:01:18.240
for accessories as opposed to the standard USB 4 minimum of just 7 1/2

00:01:15.680 --> 00:01:21.640
Watts this means that Thunderbolt 5 can provide extra power to higher-end

00:01:20.200 --> 00:01:26.280
laptops especially compared to Thunderbolt 4 which only mandated a

00:01:23.880 --> 00:01:30.680
minimum of 100 watts and the same is true in terms of data transfer rates

00:01:28.439 --> 00:01:36.840
Thunderbolt 5 has to provide a Max data rate of at least 80 gbits per second one

00:01:33.280 --> 00:01:38.320
way up from the 20 gig minimum of USB 4

00:01:36.840 --> 00:01:42.240
but what does this mean in more practical terms for example if you're

00:01:40.240 --> 00:01:46.479
connecting monitors storage or an external GPU we'll tell you right after

00:01:44.240 --> 00:01:52.880
we thank the sponsor of this video MSI meet the radx axe 6600 gaming router

00:01:50.240 --> 00:01:58.640
your ultimate gaming Ally it offers triband support with

00:01:55.640 --> 00:02:02.159
eight streams delivering up to 6.6 GBS

00:01:58.640 --> 00:02:04.039
per second of speed its AI qos system

00:02:02.159 --> 00:02:08.800

00:02:05.880 --> 00:02:12.720
prioritizes tasks for Peak Performance take your gaming to the next level with

00:02:10.679 --> 00:02:16.920
ultra fast and reliable connections check it out down below now if we're

00:02:14.560 --> 00:02:21.840
talking transferring data over the PCI Express 4.0 bus that Thunderbolt 5

00:02:19.040 --> 00:02:26.760
supports you'll have 64 gbits per second of speed which is roughly equivalent to

00:02:23.879 --> 00:02:31.280
four PCI Express 4.0 Lanes although external GPU enclosures haven't been in

00:02:28.879 --> 00:02:36.040
Vogue for a while Intel is touting Thunderbolt 5 as a way to get better

00:02:33.280 --> 00:02:40.360
performance if you are using an egpu as it doubles Thunderbolt 4's PCI Express

00:02:38.640 --> 00:02:44.480
bandwidth while the performance still won't be the same as plugging a card

00:02:42.159 --> 00:02:48.480
into a fulllength internal slot it should still be a noticeable improvement

00:02:46.400 --> 00:02:53.040
over existing Solutions and although the equivalent of four lanes is a bit of a

00:02:50.560 --> 00:02:57.239
bottleneck for a GPU it should offer great performance for external ssds

00:02:55.480 --> 00:03:01.640
useful for video editors who need to work with large amounts of footage so

00:02:59.360 --> 00:03:06.319
what about the those 80 and 120 GB numbers we previously discussed in

00:03:03.640 --> 00:03:11.040
addition to matching General USB 4v2 data transfer speeds these higher data

00:03:08.720 --> 00:03:15.760
rates are useful for monitors the upgraded speeds over Thunderbolt 4

00:03:13.040 --> 00:03:19.879
enable a pair of Daisy change 6K monitors and that might sound like a

00:03:17.640 --> 00:03:24.040
fairly weird resolution but it's relatively common in professional grade

00:03:21.760 --> 00:03:29.840
displays for more standard or gaming type setup you can drive three 4K

00:03:26.440 --> 00:03:32.159
displays at 144 Herz as well Thunderbolt

00:03:29.840 --> 00:03:35.959
5 will switch into 120 GB mode automatically when a display needs the

00:03:33.879 --> 00:03:40.040
extra bandwidth but Intel is still sorting out exactly what display modes

00:03:38.239 --> 00:03:44.159
will trigger that switch at the time we wrote this video to achieve these higher

00:03:42.120 --> 00:03:50.040
data rates Thunderbolt 5 uses what's called pam3 signaling we went over pam3

00:03:47.840 --> 00:03:54.439
in more detail in this video but basically by sending signals at three

00:03:52.319 --> 00:03:59.680
different voltage levels instead of two Thunderbolt 5 can effectively transmit 1

00:03:57.159 --> 00:04:04.879
and 1/2 bits per cycle instead of just just one pretty cool but when should we

00:04:02.879 --> 00:04:10.079
expect products supporting Thunderbolt 5 to hit the shelves and is it a musthave

00:04:07.760 --> 00:04:13.959
piece of tech well the first devices should be coming out in 2024 but

00:04:12.079 --> 00:04:17.840
Thunderbolt 5 will likely Remain the province of enthusiasts who need the

00:04:15.840 --> 00:04:21.440
higher bandwidth at least for now especially since you don't have to have

00:04:19.600 --> 00:04:25.280
Thunderbolt 5 to take advantage of the latest version of USB power delivery if

00:04:23.840 --> 00:04:29.800
you're just trying to do something like charge your laptop sadly we don't yet

00:04:27.919 --> 00:04:36.240
live in a world where we're all using a displays on the regular but one

00:04:33.600 --> 00:04:39.440
