Love it. I was worried that we were not going to get as much bandwidth as we initially did but now at least it’s safe to say that the future is looking bright for arm macs.🤔

[@2010Music4eva]

How do you avoid Apple suing you for using the images? Or are they Apple device like image but not one to one?

[@samsulummasamsulumma6898]

Sounds good, but they could have made things clearer... I mean that's a lot of things to remember and look for. And, once again, I dislike the usb-c connector because it is not physically robust at all. One wrong move and you damage something.

[@DavidA20200]

Screw thunderbolt 4 if there’s no speed upgrade.

[@truecuckoo]

That is the weirdest Thunderbolt update ever.. More like Thunderbolt 3.01? USB4 is one of the best updates ever though. I thought the most important thing to update with TB was to get the speed and dual bandwidth(?) to match a PCI slot so that eGPU’s and such can live up to their full potential? It should be mandatory from now on to print an icon next to every port, and onto every cable, telling us what it is.

[@pauldanielmooney]

Not knowing what the cable will support is my only gripe with USB-C. What version of USB? What kind of power delivery? Even just something indicating that it's dedicated to one purpose. I have a cable that's displayport on one end and plugged into my monitor and USB-C on the other, but you wouldn't know it's a display port only cable unless you trace it back to its source. Or those 'special' cables Oneplus has for fast charging should have some kind of indicator on them. USB-IF needs to get on that.

[@fuseteam]

in the end i guess they chose an umambiguous branding difference to ensure a certain minimal standard, not sure why they create an addtional controller chip however as they could just enforce any usb4 that meet their criteria to be certified as thunderbolt 4. tho i suppose since thunderbolt 4 will be integrated into their new cpus we have no idea if thunderbolt 4 devices will even require a chip at this point. also apple silicon supporting thunderbolt may also be an reason by they need a controller chip out there hmmm

[@user-kc1tf7zm3b]

Watching this video is a hundred times easier than reading Intel's press briefing!

[@awzsdrcfgybhjimklp]

I was really worried about if Apple would continue to use the thunderbolt specification in the future ARM based Macs, it is a relief to hear that they will be using thunderbolt 4 and continue to support thunderbolt 3.

[@NonsensicalSpudz]

Valid thought aswell, luckily thunderbolt is no longer propriety to intel

[@Enxuvjeshxuf]

Intel made thunderbolt in collaboration with Apple so I didn’t have any doubts about it not being supported tbh

[@Inazarab]

But Apple didn't say they'd support thunderbolt 4 specifically, just that they'd support thunderbolt. They may just continue to use thunderbolt 3 in their ARM macs. They will probably support Thunderbolt 4 but it wasn't stated explicitly.

[@qubex]

Requiring Intel’s VT-d protection for DMA is actually a massive improvement in terms of security. As it currently stands plugging a malicious Thunderbolt 3 device into your machine can read or write to your system’s RAM and do nefarious things such as retrieve sensitive information or overwrite your password with a known one so the attacker can log in as if they were you.

[@robeigner4390]

Thunderbolt 4 would still require the Intel chip because of VT-d. What Apple might be trying to do is work with Intel to allow Apple's T2 chip to also do what the VT-d chip does. From extremetech article: "Alternately, it’s possible that Intel and Apple will sign some kind of technology license, allowing the DMA protection Intel enforces via VT-d to be implemented on a future Apple ARM chip or specialized security processor like the T2." Without this agreement, Apple would still have to buy and install the VT-d chip, which is worthless on a Mac since Apple already has plenty of specialized security hardware and software and doesn't need anything from Intel. I don't know what external component vendors will be required to do to continue to support Thunderbolt but hopefully they won't have to continue to use Intel's overpriced hardware, thereby being able to reduce the cost on Thunderbolt peripherals.

[@lawrence_SoCal]

I read that security requirement isn’t Intel specific, but rather that style of protection, such that AMD system are a possibility (and AMD has released statement to this effect)

The PCIe bandwidth being doubled to 32 Gb/s seems like a pretty big jump to me. I feel like this would make both high and low end eGPU setups much more worthwhile.

Many people will be mislead by what is happening, this video blows away lots of the fog. Thank you MT.

[@IliaKaygorodov]

For me the main mystery comes one we talk about power adapters (power delivery). It is stated that USB-C connector can transfer up to 100w of energy. But for example Dell has AC adapters for XPS/Precision line of laptops, that provides 130w (e.g. www.dell.com/en-us/shop/dell-130-watt-type-c-3-prong-ac-adapter-with-32-ft-power-cord/apd/450-ahom/pc-accessories) . And it works. How could that be?

[@kornenator]

USB Type-C can support DisplayPort output without TB3. The problem (difference) comes when you want to hook up multiple displays, then USB 3.2 bandwidth might not be enough.

[@JasonFiske]

A post M1 Mac update to this would be good. We are seeing USB4 / TB4 Docks and they seem to work well, although they all seem to have a front side input which is good for laptops but bad for desktops. The M1 killed eGPU support. USB4 / TB4 cables aren’t available.

[@sadatnafis2032]

egpus perform worse than dgpu in mb pro in some peoductivity test despite the egpu having more raw performance. And that happens due to bandwith limitaion. So 32gbps on tb4 (instead of 16gbps on tb3) should resolve the issue right?

[@MaxTechOfficial]

That’s the minimum spec. I think Thunderbolt 3 already does 32Gbps but I’m not sure if it has other limitations on top of that which could be removed with Thunderbolt 4.

Didn't Apple develop the original Thunderbolt with Intel?

[@sriramsundar8388]

Yes but Intel bought the rights back. That's why they were able to license for Windows computers that even runs with AMD chipsets.

[@UltimateAlgorithm]

They developed it together but Intel owns the rights.

[@cloverlief]

The most important 2 features of Thunderbolt 4. 1. Minimum standard for cables and support are raised, so you don't get below spec devices on a daisy chain which can hinder other devices. 2. This is the biggest one. Thunderbolt 4 requires all devices to have DMA protection so it can be locked down. DMA hack vectors keep these devices out of profitable government contracts and some businesses. As TBT is going to on ARM Macs, it makes you wonder how much involvement Intel has on this, and possibly why legal X86 emulation (at least in the demo) worked so well.

Can you use a Thunderbolt 3/4 cable on a USB4 port?

[@deldarel]

That's kinda disappointing. Nice streamlining and I like the longer cable a ton, but man, a doubling in speed would have been nice. Daisy chaining doesn't make sense if the main device saturates the connection, which egpus do. Also, given that this standard will be around for a few years, no mention of pcie gen 4 is a bit worrying.

[@benjaminplut9448]

Just a few factual errors I thought I'd correct: usb c is just the connector, you could also have a usb c port that's usb 2(notably some early usb c phones had this) not just the variations of 3 and 4, also usb c also supports displayport (not 100% of the time, like pc motherboards with a ryzen chip without integrated graphics won't output anything if you tried to connect display over usb c port on the motherboard) not just thunderbolt

[@LeonardoAlexi]

As someone who has read extensively on the topics of USB-C, USB 3 (all versions), USB4, Thunderbolt 3 & Thunderbolt 4, I can tell you that this video does the best job I've ever seen in clarifying these concepts. Thank you very much! 3 things I'm not clear about: 1. When a laptop manufacturer chooses to implement Thunderbolt 4 (40 Gbps of course), does that port have to support USB4 40 Gbps, or can the manufacturer choose to only support USB4 20 Gbps? 'Cause remember, with Thunderbolt 3 ports, the TB3 connection is at 40 Gbps, but the USB connection could either be SuperSpeed 10 Gbps or SuperSpeed 20 Gbps. That was left up to the manufacturer, so now I'm wondering whether it's the same with USB4 40 Gbps & USB4 20 Gbps. 2. I saw the compact Thunderbolt 4 dock. My question is: When Intel says the dock has four (4) Thunderbolt 4 ports, does that include the port that's connected to the laptop? In other words, will we have a total of five (5) ports - One connected to the laptop, and four (4) free ones, or will we have a total of four (4) ports - one connected to the laptop, and three (3) free ones? 3. The compact Thunderbolt 4 dock, is it only powered via the TB4 connection to the laptop, or does it require its own power supply?

[@sector046]

1. Yes. In a nutshell, USB4 is essentially combining both USB 3 Gen 2x2 and Thunderbolt 3 into a single standard. However, in USB4, Thunderbolt 3 is optional, meaning that you could have 20-40 Gbps bandwidth depending on the laptop manufacturer's decision to use Thunderbolt 3 or not. Now, in Thunderbolt 4, all they're really doing is using USB4, but forcing the usage of Thunderbolt 3 for 40 Gbps bandwidth (bidirectional) and forcing DMA security. In Thunderbolt 4, they're achieving the higher display resolutions by allowing the data lanes to change to a single direction, enabling 80 Gbps of bandwidth for video. 2. The connection from a dock/hub to the laptop is referred to an upstream port, whereas the connection from a dock/hub to another peripheral is a downstream port. My assumption is that four Thunderbolt ports means that there are four downstream ports for peripherals and one upstream port for the laptop. 3. Most all docks I've seen are self-powered, so I'd expect this to be the same. Hubs are different as they'll draw power directly from the device and can sometimes offer the ability to provide power.

[@mamitch512]

[@edthom2210]

Why don’t all vendors agree on a spec instead of making it so confusing to the consumers?

[@RodLandaeta]

He is completely leaving outside the fact the new thunderbolt 4, requiring DMA protection means someone can't read your memory by just plugging a dongle to your computer. This is a huge security improvement on the protocol that wasn't included as a minimum specification before.

[@user_anthony]

So a future with thunderbolt still exists, cool. But the real question i have now is whats the future of egpus?

[@user_anthony]

Cause as it sits, we generically know what a desktop grade gpus looks like. But since apple is rumored to be leaving amd graphics, then whats the replacement for desktop gpus? I figure that apple has a plan for high end graphics, but the next question is whether or not it will actually look like current gpus or will it be a radically different design? Cause if thats the case, then buying an egpu now in the long run will be pointless since we have no idea if the future of apple gpus will physically be supported by current enclosures. Yeah if you buy an intel mac it’ll be supported and used for a while, the transition time and probably a few years after. But say if you own an egpu now then upgrade to an apple silicone mac, at what point does it become obsolete? Since there are no reports on this front yet, i see this as a great way for apple to brand its own enclosure and set of graphics or basically sell a redesigned afterburner card that will be a “thoughtfully designed” egpu. I can see them telling us how “you dont need to choose a card and hope it fits in your enclosure” or “never worry about set up and building, just plug it in and it works”

[@kklkwong7892]

Disappointed that TB4 is still 40Gb/s. I was hoping the new one would improve egpu performance

Ive been watching what feels like 50 video at this point trying to understand this concept a little more. This was the best overview so far on the three of the latest releases, but i can't find one that breaks down the connections between devices. Technically i can buy a bad cable for $5 and it'll charge/transfer whatever but not efficiently or at the risk of harming devices. So I what I'm trying to understand is if your device has Thunderbolt 3, does your cable need to be specifically thunderbolt 3? Does your charging block specifically need to be thunderbolt 3? Does it matter if the cable is thunderbolt 4, but your charging block is USB 2.2x2? That's the part I'm struggling to find any information on.

[@keith_5584]

1:22 It can get pretty faulty if it gets dust in it, or if the shield snaps from the PCB because the joint was not strong enough. Granted, usb3.0 type A was pretty irritating, especially when something forced them back to 2.0 mode. Type-C smashed that problem. Do not get me wrong all 3 ports are very awesome, but someone needs to solve the strength and conduction problems before trying to shove 40gib/s through the cable. I think it could be as simple as using those old Kingston lock ports to add structural rigidity. (For docks, and maybe like a sidecar to 90 the ports over.) Never-the-less, great video, and happy to have it and share it before confusion sets in.

[@markhollis5850]

Apple’s current M1-based laptops as well as the Mac Mini support Thunderbolt 4. I do not know if they are paying Intel any royalties for Thunderbolt 4 support, but the support is integrated on the M1 chip. This means, you may use a Thunderbolt 4 hub with any of the M1 Macs. The biggest complaint I hear about the M1 Macs is the fact that they only have two Thunderbolt ports (especially the Mac Mini). But the Intel-based Mac Mini with four Thunderbolt ports only has two Intel Thunderbolt controllers. If you use a Thunderbolt 4 hub with a Mac Mini, you wind up with four ports at the same speed as the ports on the Intel-based Mac Mini (and yes, I do understand that you have to pay more than the cost of the Mac Mini for that capability, but I find it understandable that Apple chose to not build a Thunderbolt 4 hub into the Mac Mini).

Apple macs will continue to support thunderbolt, but it doesn't say which generation. We know that USB 4 can 'carry' thunderbolt 3, so I'd say the new apple silicon macs will just be USB4 (which supports Thunderbolt 3).
