Intel showed us the goods on probably the single thing I'm most excited about from CES 2024, and it's...Thunderbolt? Seriously, this is so cool. Not only that, but Wi-Fi 7 seems like it will actually be an increase that actually matters to regular people- as well as niche corner-case weridos like me lol

I was just about to...
😂
gasp, ive been shooken
MB/s is a bit clearer of a distinction from Mbps than "MBps"
How come Cao didn’t catch that
Cool
I've always wondered why it's not been possible to "just plug in a USB from one PC to another" it seems like such an obvious use case
just use an ethernet cable and define the subnet as the same
@@alpha.wintermute i think you miss the point
There were specialized cables in the past that did that but required software. A main reason you can't do it normally is that USB is based on serial, so the send/receive wire placement matters on the connector. To get around this the USB spec uses the shape of the connector to indicate which side is the host and which side is the peripheral. Plugging in a USB A connection on both ends to hosts would usually cause them both to send 5 volts down the line and try to transmit to each other's transmit wire.
I was wondering why I couldn't plug the steam deck in
you actually could to this with thunderbolt on apple for eons. and imacs could work as displays for quite some time too.
"Once everyone makes the switch [to WiFi 7]"
Me on WiFi 4:
Wifi 4 is n for context. And wifi 7 is be.
CES 2024 has probably been the best CES showcase I think I have seen in years
- Cool new real world Thunderbolt applications that can be enabled via software (wish it gets integrated into USB4)
- Amazing new laptops that are finally on par and more creative than Macs (dual screen, Zephryus G14, etc)
- Bleeding edge display tech with super bright displays, gen 3 QD-OLED and microLED slowly making its way into the market with transparent and bezel less displays)
I'm so excited for the tech that will be coming out this year. We finally seem to be ramping up in competition in pretty much all segments in tech yet again - similar to how CPUs massively improved after Ryzen and Apple Silicon
It's already in USB4 (the TB4 part of it). PCIe always has been point-to-point so it's just matter of drivers and software
@@MrMediator24The "problem" with USB 4 is that it doesn’t require anything from TB4 to be implemented, everything is optional.
@@MrMediator24 Yeah USB4 is more of name that doesn't really mean anything. Everything in USB4 is optional. And in my original comment I meant, that this new protocol would be requirement is the next version of USB, like USB5.
@@LtdJorge Thunderbolt always has been Intel only, some stuff goes back into USB but not all of it, Intel makes sure of that that no one except Intel and Apple (who also have a stake in it) can implement that stuff.
@@werpu12 not anymore. Intel gave the TB4 (or TB3, can't remember now) spec to USB IF so that they implemented it in USB4.
Oh my God that thing is going to save so much time when switching from one machine to another. God bless engineers
Yeah it is great, but I will need to upgrade every computer at home and so far I have only plans to buy a new laptop this year. So probably will take at least 5 years to become totally standard.
@@ligametis from what i gathered, the sauce is in the cable, and the software, more specifically the software.
If I were to guess, you could just buy a PCIe thunderbolt card or two, and just plug it into whatever computer you need to transfer between, transfer stuff, and then take out the cards once not needed
.
@@Bomkzupstairs Wi-Fi is terrible so I can download downstairs on Ethernet with laptop and transfer to desktop upstairs, this'll be great as long as it's not too expensive
@@Bomkz unfortunately there's no such thing as a PCIe thunderbolt card or two. If your motherboard supports a (one, singular) thunderbolt card then you might be able to install one (singular). If your motherboard is like 99% of motherboards you won't even have that option, and if you connect any old thunderbolt card (ASUS ThunderboltEX, MSI THUNDERBOLTM4, GIGABYTE GC-TITAN RIDGE, etc.) you're going to find out pretty quickly that the card requires a header that your motherboard does not have, and without that header it will simply not work. This header is called JTBT1 and if you don't have one, you don't have Thunderbolt and no expansion card can give it to you.
Honestly gonna be game changing for portable storage and gaming on the go!
Not really sure how it would affect gaming on the go, it isn't wireless
Would this be good for PCVR - instead of shitty encode streaming to headset you just use this Thunderbolt Share?
@@supersuede91 OMFG YES
@@WarlordEnthusiast Portable storage for games due to space limitations on some devices allowing you to play games straight from the outside SSD/Nvme device onto the laptop or supporting portable console that doesn't have expandable storage due to the insane speed, there would be no noticeable issues.
@@supersuede91 True, there are million uses.
I dont always like vertical omnidirectiinal antennas, but when I do, they should look like they will attach to my face and make an alien explode out of my stomach.
This is something that has always blown my mind, how we can't get input onto a laptop screen from another source, like in an ideal world this would be a basic feature
Dell even had a few AIO PC models that had both HDMI out AND HDMI in. It makes total sense as then you can even plug consoles in too.
Its kinda sad as in the early days of video on PCs I believe capture cards in preview mode would DMA the image directly into the video buffer. It took so much CPU to process video, you didn't want the preview using all the CPU. This mean't you had a very low latency preview. Now you might sometimes get a low enough latency in OBS but its not guaranteed as you need a high-end PCIe capture card to have a hope of it being fast enough.
Wdym? Like RDP?
Even Apple had display inputs on pre-5K iMacs.
@@alexatkinIf it's anything like the Alienware Alpha, it's an HDMI passthrough port, not an HDMI capture card or anything like that. Source: I excitedly bought a used Alienware Alpha 5 or so years ago under the same misconception.
Thunderbolt has supported autoconf point to point ("bridge") networking for a long time. Apple had it first but windows and even linux have supported it for a while too.
Came here looking for this comment. It’s been possible for years.
Except the user experience of thunderbolt networking absolutely sucks on Windows and Microsoft has done nothing about it. Plug 2 computers in together and nothing happens, you'll need to manually change your network and file sharing options before this will work, and only in a hacky workaround way.
@@fjjwfp7819 not in my experience. Tried this just to see what would happen with my TB4 PC and my TB4 laptop. Plugged them together, a new shortcut appeared on each desktop showing the existing SMB shares of the other device. If there are network shares already setup theres nothing more to do for sharing files. I think it only did like 2-3 Gbps from one NVMe to another but I'd have to retest that. It's been a while and I'm not sure about the speeds.
Apple even has target disk mode using thunderbolt that turns the whole device into a thunderbolt drive and has since the beginning, they even had a FireWire target disk mode. This isn’t anything new, Apple mastered this years ago. It’s only a big deal because M$ is showing it off on Windows.
@@getoffmeluckycharms The trouble with Apple is they also like to randomly remove features. For example you used to be able to use an old AIO Mac as a display and they just decided to completely remove it from the OS.
It's like everyone forgot about what fire wire was capable of LOL
Edit: Holy f**k 1K likes!
was just thinking the same thing. But this seems far better!
I dont think most people even remember fire wire in general
Everyone except dankpods
Nah fr
My old firewire macs be like "am I a joke to you?"
Incredible details on the Thunderbolt capabilities and the advancements in WiFi 7 technology. The potential of having an essentially latency-free gaming experience is mind-blowing.
I’d love to see a comparison between this new Thunderbolt Share and old school Thunderbolt Bridge
It's essentially the same thing.
So Mbps or MBps?
Says Ethernet on the screen so I'm gonna assume Mbps. Really with the networking world would get over their old standard and move to MBps
First one, bits always lowercase if we were talking Bauds thatd be a different story 😊
The Labs team must have written this script 😂
He said Megabytes, but the graphic was Megabit. Clearly the quality and accuracy push didn’t last for long.
you can see that the speed in the graph is around 6400Mbps. that would equal 800MBps, so I assume Linus is right and the text is wrong
Hades has an in-game timer that shows centiseconds, so even without a high-speed camera you could have roughly verified whether the latency is under a frame by just taking some photos of both timers side-by-side.
I think what everyone missed was framebuffer to framebuffer. Two devices talking directly over the bus. This is closer to omnipath or infiniband over thunderbolt
Higher QAM values are great, but rare outside of zero attenuation, zero interference scenarios. That is to say, if there's a wall, you probably won't get to leverage those super high QAM categories. In fact the best features of newer Wi-Fi standards are *not* the ones that improve theoretical performance in overall scenarios, but the ones that marketing overlooks that improve real world performance in saturated spectrum scenarios.
Similar situation with 5G
It's crazy when you think about it. Your PC likely has (1) 1 gigabit port, and (6) 10 to 40 gigabit ports.
Which one do we use for data transfer... and which one do we use to plug in keyboards?
call me a noob, but on some cases and/or motherboards, arent they colour coded? i cant give an example cuz i dont know any example on the top of my head
USB3 is blue while USB2 is black typically but by USB3 I mean USB 3.0, 3.1, 3.2, etc... and that's only USB type A ports, USB type C, as far as I know, has no established color-coding convention. @@bumb189
Not really. The reason is max length of cable.
It's not the same
USB is a pretty bad carrier for many reasons. still. issues with bus traffic and consistency is one because it can't compete with dedicated PCIe buses vs chipset sharing. it's possible now because they just gave (USB4 PCIe capabilities. aka thunderbolt
The electrical engineer in me was rejoicing the later half of this video
There is mistake in 0:14, there should be 6400 Mbps or +- 800 MB/s, like Linus said. On graph it's little bit under 10 Gbps
800Mbps is not a particularly impressive speed for two computers attached by a 1 meter cable 😂
Yeah the caption is wrong. noob editor mistake. 800MB/s is 6.4gb/s which makes sense given the scale of the graph.
Finally, we got something useful out of USB-C using the same plug style for both ends.
LMAO, the thunderbolt transfer software looks exactly like some software that came with a USB 2.0 transfer cable years ago for a Samsung Ultra Mobile PC - it had two USB-A connectors and appeared as an autorun CD on each PC. You'd load the software, get an interface that looked basically identical, and could transfer software between the connected PCs without installing any drivers.
Heck yeah, USB A to USB A PC Transfer, that was ancient concept.
With thunderbolt essentially PCIe, the problem becomes who or how to write the driver, because eventually it will all be used by the OS.
FireWire you mean…
@@larsradtke4097 FireWire is a patented take, you won't see it outside of quite expensive devices. USB A to USB A was a thing.
My brother had a motherboard that did this with USB 1.1. It's how my AMD K6-2 rig got internet until we finally shelled out for a router.
I honestly can't wait for WiFi 7, wireless VR is a game changer for me
Linus is just a legend! Even on a show floor, even in those conditions with that amount of time and even with a boring topic like WiFi he still manages to make a 14 minute video THIS exciting.
I tip my hat to you sir 🎩
Yep, he can always fill you, with useless info.
This is a terrible vid, went the wrong way totaly.
@@msiig6476Go touch some grass buddy
The duality of man
linus says "800 megabytes per second" but the caption says "800 megabits per second" - huge difference
He also said you can install the new COD in 5 minutes. That stat translates to 800mb/s not 800mbits.
So, confusing all around.
We'll be replacing the video with the lower case be on screen changed to an upper case B.
Task Manager was showing a 10Gbps link, accounting for overhead etc 800 megabytes/s sounds right.
@@rivernile5565 isn't b a bit and B a byte?
@@MegaranatorIt very much is
I’ve never watched a sponsor segment with so much interest. Love the Wicked Cushions partnership and Dennis did a great job on the sponsor read.
It’s crazy to think that it took time, but after 25 years of USB we’re finally there haha 😆
took the long enough, now we just need this feature on the steam deck
I´ve saw this yeeeeears ago, at least the file transfer part. and before USB, through parallel, and serial, PC2PC and even LANs and WANs by means of parallel/serial
mactipiak
I still use PC without USB here, it does only BlueTooth
@@mikes989 TCP/IP is faster and older, eazy too, most systems support it out of the box.
@@lucasrem yes, but here we are talking about doing it with data links that were not intended for that in principle.
Intel's "Thunderbolt Share" is (as far as I can tell) actually just a new marketing name and a slick software suite for "xDomain" which is a technology that's been part of Thunderbolt since TB3, and I think is also part of USB4?. In fact I've used it myself to download games from one nearby laptop to another in an environment with bad Wi-Fi signal - no additional drivers required, just plug the cable in and it creates a point-to-point "virtual ethernet" network connection in Windows which can be used automatically by for example Steam library sharing. The screen sharing thing might be new though?
Looks like that is probably what this is. Regarding the screen sharing, the "xdomain" stuff can be configured to DMA ring buffers between the two sides... and who says those DMA buffers can't be GPU framebuffers if the GPU drivers were to allow it. My question would be whether there's going to be a *standard* defined specifically for framebuffer sharing over xdomain, or if this is just going to be some proprietary Intel implementation that is briefly supported before eventually fading into obscurity.
yes, looks like it is just a rebranding / renaming of the feature - not of a software suite. When you plug TB3 laptops toegether it just works like that, does not need extra sofware.
Steam library sharing will work, but actually dragging files across without a file server doesn't.
as an expert, i'd really like to know why exactly routers are so fucking expensive
This is extremely cool! Macs have had the file transferring thing for years, but the ability to just, use the KVM of another PC is SO COOL
That's incredible given that McAfee is on that laptop slowing it down
You guys really missed an opportunity to make a steamed cauliflower ear joke in that ad read.
It's 2min and somebody already submitted sponsor segment damn u r real hero who ever doing it
IKR such heroes, they even fkn appear in hindi videos lmao
ikr?
Is it MB/s or Mbps? Bytes or bits? Linus says one thing, the subtitles the other thing.
Right. 800 MBps is impressive, 800 Mbps is much less impressive
This is the most exciting thing I've seen at CES.
The thunderbolt thing feels a lot like FireWire. All the cool stuff Apple did with it I wish had been available everywhere else. Plugging a Mac into another Mac with FireWire and target disk mode was awesome. Glad to see a lot of similar features in Thunderbolt. Looking forward to using it.
So freaking excited! One of many reasons I love thunderbolt, more thunderbolt innovations please!
Really impressed with that Thunderbolt 4 software demo Intel cooked up. I would absolutely use that on a daily basis.
i remember this cable from a video you made a couple years back, but it was blurred and i was always curious to see what it was. glad to finally find out
Who remembers Laplink?
This would be incredible if it could work over a longer cable. Can't think of a situation where I'd want to stream a game to a device 2 feet away.
He mentioned 'passive' cable. So if you get a powered Thunderbolt cable, it can amplify the signal to reach a longer distance.
Alternatively, you'd want something like this to go over fiber optic transceivers for serious distance.
On my desk I have a Mac to do light stuff and a windows to game/work, it takes me like 10sec to switch computers
If I can just connect both with a thunderbolt cable and make the switch seamlessly, I’m all in
Wicked cushions are good they seem to be holding up better than the OEM ones for me on Bose QC 35 II the stitches was failing ripping apart so I had to replace them like once a year and I found the amazon Chinese ones lasted the same til I found these wicked ones which said they are upgraded durability as they are stitched and glued together and so far so good on durability
I bought a set to replace my worn out Beyerdynamic cushions from one of the older LTT ads and they were way better than I expected. The cooling gel really works!
They're certainly good on my Maxwell that I've been using them on for months now :).
I guess....."You can't stop the Thunderbolt!"
Thunderbolt had that for years, as somebody already pointed out, but I'm waiting for a thing like a zero-ethernet USB cable like the zero-modem serial cable back in the days,
I know something similar to this exists, but I believe they actually uses USB ethernet adapters in the middle, and not able to fully utilize full bandwidth of USB.
I would kill to have this for PCVR even if it means to have to use a cable
There's already DisplayPort Alt mode like PSVR2 uses, that carries DP directly, its just no PC VR headset manufacturer bothered to use it due to only RTX 2000 series having the USB-C ports hardwired for it. NVIDIA then ditched it on the desktop cards to save a few cents, though I think its still implemented on laptops.
@@theftking Unless you bolt the PC on your back, with a huge enough battery to power it :D
@@alexatkin AMD cards still have USB-C connection!
He did say passive cable. May be active cables coming that support longer lengths
@@theftkingmax cable length is 1 meter but who says you can’t add a signal repeater and chain multiple

*laughs in 2004 Mac’s with FireWire, migration assistant, and target disk mode*
This is most important to people who use pcvr. Hope it’s implemented there.
0:12 The text is wrong, it’s supposed to be 800 MBps, fix it Linus!
I came here to say the same thing 🤦♂️🤦♂️🤦♂️
For an old render pipeline I used at my home office I used TB3 to do data moves at 10Gbps in Windows through the networking protocol in the cable. Great performance without a prohibitively expensive network upgrade.
6:50 yeah I have 50Mbps down in Germany. No need for WiFi 7 😢
That direct cable thing is awesome. Bring it on 👍
With regards to that spider from hell router monstrosity... Sorry, but where the hell am I going to hide that? I really hope there will be some sensible designs.
Also, hoping these routers will have decent connections on the wired side. And then I dont mean just 2.5Gb, but 5 or even 10Gb ports.
Ubiquiti have already launched a WiFi 7 AP so they're out there
Now I finally know what Intel does instead of making competitive processors. lol
0:20 what is that sound? Is someone hitting a bong? 😂😂
I remember years ago using Asus Crosslink USB dongles to transfer files from one PC to another, as well as share the network access... It was slow and janky, but lord was it useful. This being part of the specs is cool.
20+ years and finally they've added intra computer communication... Oh wait this is pretty much just NAT+IP routing over thunderbolt
remember when we had local serial connection using our serial ports ? (null-modems I think?)
The only reason we're getting this variant is because Intel decided to keep the info to itself instead of sharing it.
It's not a super secret invention or a high tech innovation.
The hardware could do it all along.
It is pure greed that stopped it from being shared and we need to install 'special software' to use it, because it isn't available at the driver/OS level.
Regarding Thunderbolt Share: But Leenous, you've been able to do this (this is considering the length of the cable) over ethernet since... well at least since 2012 when it was my first experience connecting 2 computers via ethernet and setting the nic's to the same IP subnet.
He isn't talking about "being able to link two computers together", he's talking about being able to link them together at up to 40GBit without the overhead of actual network interfaces.
@@alexatkin but you still have the overhead somewhere. You don't think there's any with thunderbolt?
need this native in smart TVs so I can stream 4090 to my livingroom
This reminds me of when I was in high school we used to have a program on our high schools computers that allowed us to transfer files from computer to computer via a Serial cable
They used to call this a "sneakernet" when we did file transfers with parallel ports, then serial ports, and then later USB. It's not new, just faster, like most everything else in personal computing.
Finally, something truly exciting, realistic, and working from CES.
Dennis doing the ads is the best thing to ever happen to LTT
7:17 did it just move.
You can't just have 2 windows computers in the same room and conveniently share files between them! A cable is good, but why wifi is out of the question is still infuriating.
Meh, let's chill on wifi file sharing, go spend that money on a Thunderbolt 4 cable, and quit the yapping! :D ~consumerism~
My understanding is that wifi still has radio interference that could create a lossy signal. Through a cable, you are able to at least shield that information from outside information that could possibly corrupt the signal.
Wifi sharing between Windows computers has been a thing for years. Nobody seems to know about it, but it has been built into Windows since Windows 10.
@SentriSable sure, though you could use error checking algorithms (e.g. based on MD5 sums) to correct any incorrect bits on file transfers at the cost of some latency and possibly stuttering (if it's a stream).
I use an app called ShereAnywhere. Works wonders
Intel 🐐
First time (since I first started watching close to a decade ago) checking out the LTT sponsor - well done!
There was and could ever be, only one, Prince. He doesn’t need WiFi anymore.
0:12 Wrong unit.
Came here to say this, I didn't look at the graph at first and I thought he was legitimately celebrating sub 1 gigabit speeds 😂
@@brozus1515 Well...800 megabytes isnt fast either. Especially if you can have 10 gigabit ethernet in some places.
@@alexturnbackthearmy1907 yeah that's what I was saying
@05:26, if you slow down the playback to 0.25x, there's white flash on the handheld, and a lag to when it shows on the laptop, but it's super short and amazing.
EDIT: Also, your Samsung Note 9 can record at 240fps. That's fast enough slow mo to see the latency on this setup. Maybe you weren't allowed to record it.
This could be amazing for future standalone VR HMDs
im NDA-ed outta my mind right now!
This would be sick for VR, imagine having a belt mounted vr compute system, attached to a vr display without the need to wear the compute on your face!
800 MB/s or 800Mbps? Big difference
All of this is genuinely just so cool, it makes me really excited. I actually kinda want a 16x16 Wifi 7 AP. I know it would be ridiculous but it’d be kinda amazing.
It's what I've been searching for, for months now since my laptop hdmi port died.
This has been possible under linux for a while now, as an extension of basically the pcie non transparent bridging featureset
You can do it in Windows and Macs too. Been a thing since like 2011. No idea how this is new.
this looks super cool, file transfers between computers over thunderbolt would be so much better for temporary situations instead of going through the annoying tedium of setting up network shares
1:07 Jesus Christ! I was eating!
Please warn me next time 😂
A even better example of when the thunderbolt connection would be useful is for road trips or camping where you don't have a WiFi network and don't want to set up a hotspot that will be slower than this.
That router triggers my arachnophobia HARD lol
I did the fileshare part of this when I setup my new Mac from the old one 40 gigabit vs 10
I used to do file transfers like this 30 years ago with parallel port cables.
All these numbers mean little to me with my 27mb internet, and yes thats bits not bytes. The joys of rural England.

Okay but how fast can I transfer my 10 yottabytes of "homework" I need to know... For a friend's reasons 🤔
Wow these are actually some useful advancements in areas that were long overdue for improvements!
Here's me remembering playing head to head over a parallel cable 😅
A cable/software package that lets you use another computer as a display? About time.
Haha was getting flashbacks from using crossover cables when i was a kid at the start.
Just what we need, more uses of already overloaded RF spectrum.
Now this is the most interesting development in cables for ages.😮
MacBook or Mac can kinda of do that. I just randomly found this out when putting 2 M3 Max MacBook Pros together and it just allowed me to do a extended screen between the 2 MacBooks. I was socked by this because it was my first time seeing anything like this and they where not even connected by a wire they just simply noticed oh I'm near another MacBook and it seamlessly connected to the other one and just went into extended display without needing to configure it.The best part was it was also smooth with no delay between the 2 screens and keyboard and trackpads. Like no matter where i moved the arrow on my trackpad I could go to the 2nd MacBook and move the trackpad and it could just pick up from there.
