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.

[@user-kc1tf7zm3b]

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

[@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

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.

[@coaltrain2299]

if they don't switch to usb c they will always have a dogshit cord, usb c is better in every way

[@schockofrescher]

@@coaltrain2299what are you yapping about?

[@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)

[@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.

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.

[@Steven-fv8xw]

Why does Thunderbolt 4 refuse to double its bandwidth even though PCIE4.0 has doubled its bandwidth? PCIe4.0*4 has a bandwidth of 80Gbits/s

[@Anderson_Hwang]

Intel can grab more money from us again with TB4

[@StringBard]

Proprietary hardware = not for me

[@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?

[@Tiffs-bookshelf]

So can you tell me what the difference would be on the new iMac with the usb4 and thunderbolt.

[@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.

[@alchemistTi]

Did I miss backwards compatibility info? My laptop has TB3, so will I be able to plug in USB-4/TB4 accessories into it and take advantage of the same 40Gbps theoretical maximum speed?

[@MaxTechOfficial]

yes, as long as your TB4 cable or accessory supports the full speeds that it can.

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.

It's been a dream of mine to run my computers in one room of my house and just run cables to each room. That way I can keep one room climate controlled and not worry too much about noise and heat production. Would a fiber optic Thunderbolt 3 cable to a peripheral hub allow me to do this?

[@BankruptGreek]

So if you want a good thunderbolt 3 and USB 4 cable you could get a thunderbolt 4 cable? What I am getting from the video is that thunderbolt 4 is practically a certification that a cable can support the full functionality of thunderbolt3/usb4

[@arunchhatwani1754]

@6:50 you say intel requires thunderbolt 4 to support two 4K displays. How is that possible? One cable supporting 2 displays? Can someone clarify

[@sector046]

This is possible through a feature called Multi Stream Transport (MST). Generally, when you connect an external display through a Type C display dongle, they use Single Stream Transport (SST). There's actually Type C hubs and docks that support MST that you can buy right now for most devices, but they will support 2 monitors of lower resolutions, like 2560x1440 (The MST device is using USB Gen 2x2 for the 20 Gbps bandwidth because two 2560x1440 displays require ~12 Gbps data bandwidth). Thunderbolt 3 increases the resolution to 4K because it brings 40 Gbps data bandwidth, and two 4k displays with 60Hz refresh rate require ~30 Gbps. 40 Gbps means a maximum single display resolution of 5K can be supported because 5K requires ~27 Gbps of data bandwidth. Now Thunderbolt 4 brings in a possible 80 Gbps of bandwidth by allowing the changing of direction of data lanes for video; this allows for two 4K monitors with 120Hz refresh rate requiring ~60 Gbps or a single 8K monitor with 60Hz also requiring ~60 Gbps. Source: I'm an engineer who works with the Type C and display drivers in the Linux kernel.

[@KolnFriedChicken]

Within the minimum specs for USB4 on the Intel board it doesn't say anything about PCIe connection, on TB3 it says minimum requirement 16 GBytes/s which would be 2xPCIe3.0 or 1xPCIe4, though afaik TB3 is always connected to 4 PCIe3.0 lanes... So I'm even more confused than before. Does USB4 always have TB3 support and does TB3 means what TB3 means (4xPCIe3.0 lanes) or does it sometimes have TB support, sometimes not and sometimes it may have but is connected with fewer lanes as the standard otherwise dictates????

[@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.

[@dryzd]

[@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”

[@LeRoy0345]

So will thunderbolt 3 accessories work with a USB4 port? And vice versa?

[@cheweebecca3697]

So does that mean we're going to start getting cheaper TB3 accessories ie. external hard drives(or enclosures)?

[@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.
