Shadowing Practice: USB4 is a Glorious Mess - Learn English Speaking with Video

1
USB 4 is an absolute game changer.
2
We're talking 40 gigabit per second data rates, support for 8K displays and external GPUs, single cable docking at up to 240 watt charging rates,
3
and all over the same USB type C connectors and cables that you have come to know and to...
4
Yes!
5
What?
6
Actually, USB 4 is more like a collection of optional standards, okay?
7
It sounds like what you're talking about is USB 4 Gen 3x2 with some of those optional features implemented.
8
So your sponsor, Origin PC, would probably want you to clarify that, so okay.
9
Pedantic Riley is very annoying, but he's also right.
10
I mean, it shouldn't surprise me coming from the same industry consortium that brought us naming like USB 3.2 Gen 2x2,
11
but five years after Intel's announcement that they would open source Thunderbolt, USB 4 is finally out in force,
12
and has turned out to be one of the most confusing standards ever to make it onto a consumer PC.
13
The good news though, is that by the time we're finished here, you will understand both its pros and cons,
14
and how it operates or doesn't with other standards like Thunderbolt, including real-world examples.
15
The simple explanation really is
16
that USB 4 is an open version of Thunderbolt 3 based on the specifications that Intel released back in 2017.
17
There is a lot to love about this move.
18
For one thing, it frees vendors from the shackles of Intel's notoriously onerous certification process.
19
And for another, it allows non-Intel CPU manufacturers, like Apple or especially AMD, who didn't co-develop the standard,
20
to support features that used to be Thunderbolt exclusive, like 40 gigabit data rates, daisy chaining together multiple devices,
21
and PCIe tunneling, which is super cool,
22
and allows you to turn your USB-C port into a PCI Express connection for devices like external GPUs and other add-on cards.
23
The problem is that when you free the notoriously cheapskate computer industry from compliance programs, you invite shortcuts.
24
And USB 4 invites a lot of shortcuts.
25
In no particular order, here are the optional components of the spec that can be left off of your device,
26
while still allowing the vendor to slap USB 4 on the spec sheet.
27
40 gigabit transfer rates, 20 gigabit USB 3.2,
28
Thunderbolt alternate mode, USB-C alternate mode, and yes, PCIe tunneling.
29
Yeah.
30
In a world where almost nothing you can connect to a
31
laptop needs the speed of even a last gen USB 3.20 gig port, isn't the whole point of USB 4,
32
PCIe tunneling and interoperability with Thunderbolt 3 devices?
33
Well, Microsoft sure thought so, which is why they actually require external USB 4 ports on Windows 11 devices to support PCIe tunneling,
34
which theoretically ensures backwards compatibility with Thunderbolt 3 devices.
35
But there is no such guarantee if you were to buy a bare motherboard or a non-Windows device.
36
And from my conversations with a device maker whose previous Thunderbolt 3 notebook actually never ended up getting certified by Intel,
37
there's a lot more to this interoperability than just checking a box for PCIe tunneling.
38
Making matters even more confusing, Microsoft does not appear to have mandates in place for any of the other features.
39
The good news is that when it works, it works really well.
40
Here is a small bushel of Thunderbolt 3,
41
Thunderbolt 4, and USB 4 devices that we've tried on the Voyager A1600 gaming and content creation laptop
42
that Corsair provided for this video.
43
And I'm gonna show you guys what the experience is like
44
on a USB 4 laptop after the short message from our sponsor.
45
Corsair packs the Voyager A1600 with high performance gear like their Vengeance DDR5 memory, and yet managed to keep it amazingly slim.
46
The integrated Elgato Steam Deck allows you to map streaming commands
47
and keyboard shortcuts to 10 easy access customizable shortcut buttons using simple drag and drop customization.
48
And Corsair's iCue software lets you fully customize the system's look, monitor performance, and manage your Corsair devices so you can update and fine tune the settings to your needs.
49
It comes with a one-year comprehensive warranty for peace of mind, making it the premier choice for laptop PC gaming or content creation in a super compact package.
50

51
For our first trick, we'll be trying to connect a couple of Thunderbolt 3 devices to our USB 4 laptop.
52
And the reason this matters is
53
because these older devices would have been designed at a time that USB 4 compatibility wouldn't have been a consideration.
54
So if they work, it means that USB 4 is transparently compatible with Thunderbolt 3.
55
at least, okay, this one works, for these particular devices.
56
Now that first one I plugged in using a USB 4 cable, and the second one, we're gonna try an older Thunderbolt 3 cable.
57
I think we got it.
58
There it is, CalDigit 10 gig network adapter.
59
This backwards compatibility means that any Thunderbolt 3 device and USB 4 system should work with each other.
60
Now, I would expect to find some edge cases, particularly with very old devices due to Intel specific handshakes that used to be required.
61
But we didn't run into any of them while we were working on this video.
62
Now let's try a Thunderbolt 4 device.
63
In the interest of giving ourselves our best shot here, we're gonna go ahead and use a Thunderbolt 4 validated cable.
64
Look at that.
65
Easy.
66
And we don't even need that old Intel application for managing all of our connected devices.
67
I mean, I expected this to work.
68
The main difference between Thunderbolt 3 and Thunderbolt 4 is actually also in enforcement of compliance.
69
So Thunderbolt 4 requires, in order to get the Intel badge, support for two 4K displays, or a single 8K display.
70
Computers must have 32 gigabit per second of PCIe bandwidth.
71
This is to address issues folks would have with high bandwidth devices on some Thunderbolt 3 laptops,
72
particularly eGPUs, and they must support security improvements that protect your device from malicious connected devices.
73
Plugable.com actually has a great write-up on the differences between Thunderbolt 3 and Thunderbolt 4.
74
What about speed though?
75
In an attempt to crack over 20 gigabit per second of transfers, we are using three separate SSDs and our network share,
76
oh, and copying all to our boot drive at the same time.
77
3.6 gigabytes a second, yes!
78
Can confirm that we are not limited to 20 gigabit per second, even though that could be the case with USB 4.
79
Wow, those transfers are almost all done.
80
That's really impressive.
81
Those were 22 gigabyte files.
82
Mind-blowing.
83
And the most mind-blowing thing is that aside from some CalDigit devices that took a little while to be detected,
84
we didn't run into any issues using Thunderbolt devices on this laptop.
85
And those CalDigit ones, they were actually just downloading drivers in the background.
86
Wow.
87
But there is definitely more to know here we tested a lot of configurations
88
and discovered not only some differences between Thunderbolt and USB 4, but also between Apple's implementation and the one we found on the Corsair Voyager.
89
See, on a Mac, two Cinema 5K displays, this would work.
90
Just connect them to any Thunderbolt port you want and it works as expected.
91
However, when we attempt to do the same thing with the Voyager, either only one display works, Or if we go through a hub,
92
we can run both of them, but they're limited to 4K resolution.
93
Unless, dun-dun-dun-dun-dun-dun-dun, we actually unplug them from our Thunderbolt ports,
94
plug one into Thunderbolt, and one into the regular USB-C 3.2 port over on the other side.
95
Et voila, both running at 5K.
96
The reason for this is quite interesting.
97
In the Verges coverage of this laptop,
98
Corsair senior public relations specialist Justin Okbina revealed that the USB 4 ports are hooked up to the CPU for display.
99
Meanwhile, the 3.2 ports are hooked up to the GPU.
100
So they might look the same, but because they're running DisplayPort alt mode,
101
they're limited to the capabilities of whichever GPU is physically attached to them.
102
So we're able to run more than one 5K display by connecting to each of those GPUs separately.
103
This is another really interesting example of different protocols behaving in different ways, even if they go over the same connectors.
104
Now, alt mode, what we're talking about here, uses a physical chip connected to the USB port to send a signal down it that differs from standard USB.
105
Tunneling is not the same.
106
It converts the DisplayPort signal to packets that can be sent along a USB connection
107
Allowing for things like data and PCIe tunnel packets to be sent alongside
108
So your mileage may vary depending on whether your machine uses alt mode or tunneled DisplayPort
109
Poor Tanner If only Apple could have provided a display with an actual stand.
110
Okay, you're good.
111
You're unplugged Yeah, he's got the tracksuit and everything.
112
Okay.
113
Thank you Let's try some older more obscure stuff like this Akiteo dual drive dock and
114
How about this Thunderbolt archival tape backup system?
115
I remember the tape drive actually requiring special software
116
So it's possible this hard drive will show up even if the tape drive wouldn't.
117
Oh, hey, there we go.
118
Look at that.
119
That's awesome Goodbye monitor external drive and there they are They are!
120
That's wild!
121
I mean, it shouldn't surprise me that much given
122
that USB 4 is supposed to be based on the Thunderbolt spec and therefore should be the same thing,
123
but you just don't expect heck to work that well right out of the gate.
124
And there were some things that led me to believe that maybe they weren't quite the same.
125
For example, Thunderbolt has supported multiple Thunderbolt devices, daisy-chained together since the beginning.
126
But the Wikipedia page for USB 4 explicitly says that such daisy chaining is not supported.
127
To clarify, you could totally plug a Thunderbolt hub into your USB 4 laptop, and then a USB hub into that, and another one into that,
128
and so on and so forth until the signal timing becomes an issue,
129
but Intel seems to believe that connecting additional PCIe tunneling devices downstream, well that's their jam.
130
So what happens if we try it?
131
I guess we've already got this guy right here.
132
So instead of plugging our additional drives into the laptop directly, why don't we daisy chain?
133
I see the hard drive in here so pot.
134
There they are.
135
The SSDs in here have shown up.
136
But how far can we go?
137
Why don't we do a hub?
138
Oh yeah.
139
Okay, I don't know if we have to go all the way to six, but let's do one more at least here.
140
Here comes another one.
141
There they are!
142
It's all showing up!
143
I want one more!
144
I want my 10 gig Ethernet!
145
6A...
146
Oh...
147
Oh!
148
Nope, it's not like that one.
149
We got it working with anywhere from two to three devices pretty consistently,
150
but as you can see, your mileage may vary.
151
Though, this is unlikely to ever affect you.
152
Many newer Thunderbolt devices, especially hubs and docks,
153
have controllers in them that can communicate either using Thunderbolt-like PCIe tunneling protocols or traditional USB protocols.
154
So in many cases, it won't necessarily be obvious to you until you try to plug in another downstream device,
155
which protocol your device is using.
156
Now, rather than trying to run all five of these devices, let's go for a single really demanding one, an external GPU.
157
Here we go.
158
Oh, fan spinning.
159
That's a good sign.
160
There it is.
161
Our RTX 2070 external GPU.
162
Not that we'll need to upgrade the GPU anytime soon, given that this laptop has a Radeon 6800 in it already anyway.
163
But the point is that it does work.
164
And the A1600 does all of this partly thanks to AMD's inclusion of USB4 on their Zen 3 Plus Ryzen 7000 processors.
165
But in the absence of Intel's standards compliance team, it's also thanks to the way that Corsair has worked with their OEM to internally validate their implementation.
166
However, watch how easily I can break things.
167
Whoops.
168
Here's what happened there.
169
While Thunderbolt has used the same USB-C connector as USB devices for half a decade now,
170
the Thunderbolt protocol, which you've heard me refer to a few times, and it's kind of like the language that's actually being spoken over the cable,
171
well, it's closer to PCI Express than it is to USB.
172
So this, along with its traditionally much higher data rates means that it has far less tolerance for latency and inconsistency,
173
which means that cable quality matters a lot.
174
It's not all bad.
175
Like here, oh, this anchor cable is one that I specifically pulled aside for this.
176
This is pretty cool because this cable is older than the USB 4.0 spec.
177
It's just a high quality C2C cable and give it a second.
178
Oh wait, did that not work?
179
I actually tried it on a different Thunderbolt only device.
180
This network adapter.
181
And on the network adapter, it totally works in spite of this thing not having a USB operating mode.
182
That's wild.
183
Let's try this USB 4 type C cable, one that is actually a newer validated one and see if the external GPU picks up that one.
184
No. As you can see, standard USB-C cables might work fine even with Thunderbolt only devices,
185
but only the ones with the built-in signal stabilizer, like this one, are actually guaranteed to work with Thunderbolt devices.
186
And that's gonna be true for any connection using that PCIe-based Thunderbolt protocol,
187
regardless of whether it's on an Intel certified Thunderbolt device or a USB-4 device.
188
This is why USB 4 is only rated at 40 gigabit per second over a 1 meter cable
189
While Thunderbolt 4 is rated at that same speed at up to 2 meters.
190
To my knowledge, there are no non-Intel Thunderbolt USB 4 signal stabilized cable products.
191
And curiously, this is another really interesting one,
192
this active Thunderbolt 3 cable from Corning didn't work on any of our devices on our USB 4 laptop.
193
Here, hold on, I can just demonstrate this real quick.
194
There we go.
195
Yeah, no dice.
196
Which means that our days of hit or miss cable compatibility are not over, even if they are a lot better.
197
To answer the question then, is USB 4 compatible with Thunderbolt 3 and 4 devices?
198
The answer is yes, but also no. The level of compatibility really is going to come down to how good of an implementation you get.
199
The Corsair Voyager A1600 performed admirably, but it's a machine that implements far better than the bare minimum spec,
200
and one that doesn't go this far may not be as smooth.
201
And, as we saw today, your mileage may vary when it comes to unofficial features,
202
like daisy chaining and support for specialty cables like these optical ones from Corning.
203
The big question this raises then is why did the USB-IF allow half-baked USB 4 at all?
204
Well, it seems to come down to phones.
205
Mobile devices could get some very valid benefits from USB 4, like higher data rates and DisplayPort tunneling for external devices with Samsung decks or whatever.
206
But they're unlikely to need the PCIe tunneling that Thunderbolt is known for or daisy chaining and the like.
207
They're also unlikely to need this segue to our sponsor that I'm known for, because we already told you it's sponsored by Corsair.
208
If you guys enjoyed this video and you're looking to learn more about Thunderbolt, this video on short circuit shows off my very favorite Thunderbolt 4-dog.
209
It's actually, this one.
210
It's freaking awesome.

Gölgeleme Tekniği Nedir?
Gölgeleme, başlangıçta profesyonel tercüman eğitimi için geliştirilen ve çok dilli Dr. Alexander Arguelles tarafından popüler hale getirilen, bilim destekli bir dil öğrenme tekniğidir. Yöntem basit ama güçlüdür: ana dili İngilizce olan bir sesi dinler ve hemen yüksek sesle tekrar edersiniz — konuşmacıyı 1-2 saniye gecikmeyle takip eden bir gölge gibi. Pasif dinleme veya dilbilgisi alıştırmalarının aksine, gölgeleme beyninizi ve ağız kaslarınızı gerçek konuşma kalıplarını eşzamanlı olarak işlemeye ve yeniden üretmeye zorlar. Araştırmalar, telaffuz doğruluğu, tonlama, ritim, bağlı konuşma, dinleme anlama ve konuşma akıcılığını önemli ölçüde geliştirdiğini göstermektedir — bu da onu IELTS Konuşma hazırlığı ve gerçek dünya İngilizce iletişimi için en etkili yöntemlerden biri yapar.
