USB has never been easy to understand, and USB4 is no exception. How compatible is it with Thunderbolt 3? What about Thunderbolt 4? What cables can and can’t be used? Is a USB4 cable interchangeable with a Thunderbolt 4 cable?

Maybe USB wouldn't have any competition if it could actually be Universal and meet every use case. When it can't be bothered to come up with a simple naming standard because it can't be bothered to be Universal and let's manufacturers make every little piece of the standard optional of course it's not going to be universally applicable to anyone and therefore will have competition.

I'd say the biggest issue is that USB C cables (and often ports) have zero labling what so ever. USB 4 doesn't actually make this meaningfully worse when a USB 3 C to C cable could be anything from USB 1 to USB 3 (best), plus the occasional 'power only' cable (though at least those were usually C to A, and the A plug was colour coded... except, oh wait, those were often wired incorrectly, to the point where some of them could brick your machine if you used them with the wrong device)

As the "tech guy" among family and friends (as I'm sure many of you are) USB-C has caused a lot of frustration among less tech savvy people that I know and I get why it does. They look at their device, and they look at the cable/dongle they want to plug into it and they're the same. They fit together just fine, but sometimes things don't work on a pretty arbitrary basis. For example, relative A wanted to still use wired headphones with their new phone and they purchased a passive USB-C to 3.5mm adapter which worked great. Relative B sees that, buys their own adapter, then discovers that it doesn't work at all even though it's all exactly the same externally to relative A's setup. Relative B then comes to the tech guy who explains that analog audio out has to be supported by the hardware, but that not all phones support it and they get frustrated because all of that was so opaque to them. All I can really do is shrug, agree that it sucks, and offer to check compatibility on any future planned purchases.

The people at the USB consortium really went: "Fuck, one person finally figured out how the naming scheme of USB 3 works, we need to come up with something more confusing ASAP!"
Жыл бұрын
The naming scheme is purely technical. They specified what should be used for marketing and by end users. The problem is that nobody sticks to that. There's simply 5, 10, 20, 40 Gbps. They all have logo with the number. For speed that's all, you don't need anything else. There are different logos for different features like power delivery, DP alt mode and so on. You should just tell which features are supported over the standard connector and that's all. Using technical terms does not help with anything and using the standard name is just confusing as the standard describes how to do things, it does not mandate to do all of them. Like you may have safety standard saying how hot should heated steering wheel be in your car so that it does not burn your hands. You meet the standard if you don't have heated steering wheel too. If someone will now put a sticker to brag about this, it's just marketing bullshit. They did not want anyone to use technical names for marketing as those can be and are confusing to ordinary user. The worst part is that some manufacturers started using wrong names, consumers got used to them and now everyone has to use them, otherwise people will not buy their products. This one has 40Gbps USB but this one has USB 4! Let's take the newer one! That's how we end up with this mess.
@PhysicsGamer
@PhysicsGamer Жыл бұрын
​@ The issue people have is that response was utterly predictable and it's really on the USB forum that they didn't see it coming. When you have users saying "I need to do 40Gbps... 3.1 can't do those speeds? Thanks, that must be version 4, then," the idea of the "simple" marketing names falls apart entirely. Users care about what their products _do,_ at the end of the day, and right at the top of that list of functionality is _compatibility._ Consider the USB-2 to USB-3 (yes, yes, I know - but keeping it "simple" here...) transition and how the USB micro connector was handled. USB-2 cables had the same old USB micro connector as always, while USB-3 cables had an extra node on it. It was _so_ easy to explain to people "This is the bit that makes it work faster. If the port can fit this extra part of the connector then it supports faster speeds, otherwise you have to use slower cables. If you use a slower cable in a faster port, then it'll just work like it's a slower port." Nowadays it's a neverending cycle of figuring out if it's even possible for function X of device Y to work when connected to device Z. And if it is, which of the multiple poorly (or even un-) labeled USB-C form factor ports needs to be used to get that functionality. "Why does my monitor work when I plug it into this port but not this identical port on the back of my computer?" "Why does my laptop stop charging when I swap the ports my mouse and charger are using so that the cable is in a better spot?" "Why is this connection so slow? Both my devices say they support USB-3.1 speed..." "Why does plugging in an extra monitor to my dock cause my laptop to charge slowly?" "I bought the best cable I could find but it STILL won't charge my laptop... is my laptop broken or is it due to this 'fiber optic' thing?" These are all questions I've been asked which were only possible due to the mess USB has become lately. I feel like we've regressed back to the time when everything used its own proprietary charger, except now there's the added horror of all the chargers being identical.

USB never should have added optional components of the standard in any version. The entire point of USB originally, was "a USB port is a USB port". It is also extremely annoying for so many things like alt mode to exist which use USB connectors for things which aren't USB. Defacto now, it is impossible to know ahead of time if a specific device will work with a specific port without reading spec sheets, and even then it isn't clear (Thunderbolt products will often work with non certified implementations even if it isn't hinted at anywhere in the spec sheet)
Жыл бұрын
I will argue with that. We don't need 2137 different connectors so that our monkey brain can match the shape. We just need the information what it is. What's lacking (and it's mostly manufacturers fault) is how things are marked. Primary USB use is USB. You have standard logos for 5, 10, 20 and 40 Gbps. You can also guess what will be the next number if it comes out. That's all. Everything else should me clearly marked. This port has DP? Put a DP logo near it. This port has Thunderbolt 4? Put the logo on it. Does it provide 100W charging? Put a logo on it. Let people know what this port supports. With different sockets I can have expensive HDMI cable and have no way of charging my phone or I can have expensive laptop charger but I have no cable to connect the monitor. With common standard we can reduce the number of cables we have. Of course you can still buy cheaper things that don't have all features but that's your call. Otherwise we end up with stuff like we have with USB 3. Yay, I have new USB 3 micro cable. Yay, it does not fit my USB 2 device. Yay, I have to carry USB 2 and USB 3 cables now because the cable for my fast external drive does not fit my old phone. That's silly. Do I really need separate display socket in my laptop just because my phone does not have display output and I want to use the same charger for both? Or do I need to have two different chargers? Why can't I use the same cable to charge my phone, charge laptop and have display from my laptop? USB provides exactly that. I know that if my cable is good for display and charging, then I can use it to charge my phone and connect monitor to my laptop. I don't need two cables anymore. And I know that if it my laptop supports charging and display output and my monitor provides power over the same connector, I can charge my laptop from monitor. What's wrong with that? Moreover, certification is always a problem. On the one hand certification ensures that things work. On the other hand, certification is costly. So if you are too restrictive with certifying things, you have a wide market of not certified devices that may work. Now you have a choice - go for expensive certified product or cheaper not certified. Now you complain that not certified things work even though they were not certified? What kind of logic is that? The fact that something without certificate works is a problem? No. The problem is that certification is too expensive or too restrictive. That's exactly why USB does not require all features. If USB 4 would require PCIe on each and every implementation, then stuff that has other features but no PCIe would not have USB 4 certification even though it's working with it as long as you don't try to use PCIe. That's the whole point of having optional features. You don't need 40Gbit data transfer and TB4 alt mode if you want want to connect external PCIe device. Does it mean that this socket should be banned? Does it mean that you should have completely different, proprietary cable and socket for this purpose? It would be stupid if you can have PCIe through USB-C but only if you support something that you don't need. Certification should be relaxed enough to mean something. If it's too restrictive, too many devices support things without certificate, then people stop using the certificate as guidance. You have certified cable for $20 and not certified for $5? You will try the cheaper one hoping it works and complain that there's no certification but you don't want to pay for the one that paid for certification. That's the problem we have. If someone can't get certified despite supporting something, then the certificate is meaningless. If you have to pay way too much to use it, it's meaningless. It's like "only use Apple chargers to charge Apple devices". Some people will do that, most people will figure out that any USB can charge it for much lower price. Or "only use Apple USB-C cable". Why? What's the difference besides the price and marketing? None. Certificates should not be used to feel that it's more exclusive product. They should mean something and should be clearly marked. Not in the spec sheet, it should be on most devices that have enough space to put a tiny logo on it. For those few too compact devices it could be written somewhere else or provided only in spec sheet but for most computers there's enough space to put the logo on the panel near the socket. Would it be a problem if thing like Macbook had a small diagram on the bottom with all logos assigned to each port? Not really. Now it's hidden so that people don't complain about the looks and it's still on device.

The true irony is that USB was originally developed back when every device had its own connector and even things which could theoretically all be supported by the same computer wouldn't actually work together because the connectors were wrong, etc. USB was _supposed_ to unify all of the different communication standards and connectors together, so that any USB device could work with any USB port. Now, we've reached exactly the opposite state, where even through everything is now using the same connector, you can't know whether any given device will work with any given port because they're all doing different things over the same connector and there's absolutely no standardization of feature sets or functionality. In a way, the USB-IF have become the evil they sought to destroy...

USB-IF made the same mistake with USB4 that Intel did with Thunderbolt 3, by making certain features optional. The unfortunate part is what makes USB4 unique from previous standards are what were left out as options. Thunderbolt is also implemented differently by Intel across it’s CPUs. Some mobile SOCs have it integrated directly into the monolithic design of their CPUs, some are on-die but on different I/O chiplet, while others are in an external PCH on the motherboard. The performance varies with the best performance with the integrated designs. USB4 v2, DisplayPort 2.1 and Thunderbolt Next all seem to offer the same maximum features but again only Thunderbolt offers the full features specifications as default while the rest leave the best bits as options. Rumour has it the next iPhone Pro Max will feature Thunderbolt with its USB-C. I can’t wait for Thunderbolt Next

The real problem here is that devices with different capabilities all have the same "USB4" name. Presumably they did this because of pressure from vendors who want to call their product "USB4" so that it doesn't look outdated, even though they don't need, and don't want to pay to implement, all the new features.

@@rossjennings4755 multiple configurations is exactly the problem we are trying to get away from. The things that are optional for the HOST in USB4 are around 5 so even now the number of ways one could combine optional features is truly limited but it is still causing a problem. So if we were to give them different names we would have USB4 Option 1 Which doesn’t include any of the optional features then USB4 Option 2, USB4 Option 3, USB4 Option 4, USB4 Option 5 and final USB4 Option 6. What if a particular implementation is including 2 optional features out of the 5? It would mean each combination of two gets a different name. What if they combine 3 or 4? Finally the last configuration would be USB Option All for host devices that include all the options. It would be a mess and even without the naming because this is the reality, we already have such fragmentation it is already a mess. Imagine buying a laptop and having to decide between 20 different USB 4 specs. We should just have all HOST and HUB devices feature USB4 with all the options enabled. This is the only advantage Thunderbolt 4 has over USB4. I walk into a store and all I ask about a USB-C port is does it support Thunderbolt 4 and I know my new computer will be able to work with anything USB-C.

@@Furiends nah, I can totally blame USB-IF. Let's put this to this way. Which name is more sensible? "USB4 Version 2.0" or "USB 4.2"? (although, to be even more confusing, if they used sensible naming they'd start with USB 4.0 meaning that what they call version 2.0 would be USB 4.1) In "USB4 Version 1.0" (which should have been called USB 4.0) the optional features technically allow the standard to be slower than the fastest USB 3.2 standard, where as in "USB Version 2.0" has to be at least 80 Gigabits per second. So it's not like they can't make features mandatory in later versions, because they do, but the further complication is that they do their best to obfuscate the fact that there's a difference at all. This mess means that the USB 3. 2 ports on my computer technically meets the requirements for me to slap a USB4 sticker on it even though it was made before USB4 existed. This tells me that the objective of this confusing naming standard is to artificially increase adoption via a version 1.0 model. If the objective was to remain relevant they wouldn't have designed it to work that way. Under no scenario is it acceptable for a new standard to allow old Hardware to be rebranded as new.

@@JivanPal It's not a good idea. Listing not supported features means that you have to know what the supported ones are. Now imagine that USB will add a new feature. Now you have to know which features were supported by the version implemented by the device and subtract the list of not supported features to know what it can actually do. That's exactly why we had a mess before. You can't expect consumer to know each and every revision and capabilities to know exactly what should be there. Can you tell from top of your head what's the max resolution/refresh rate of DP 1.2a? I guess most people can't unless someone they check which version can do what. So having the version does not really say anything. I bet a lot of people would later buy something that does not say it does not support something only to find out later that something was not in standard yet and it was not even mentioned. Besides that you can't really force people to put logo on a product. You can prevent them from doing so. So you can tell people that to use your 'XYZ compatible" logo they have to meet certain criteria but it's very hard to force each and every manufacturer to put "XYZ not compatible" on any device that does not support something.

Mine was an Amiga 1200(still works, even the hard disk) and I had an external SCSI connector hooked up via the expansion slot on the side. It was a nightmarish sprawl of cables and crap all over my desk with devices just daisy chained taking over half my bedroom.

The only way to guarantee that a type C cable you get will work with any host and device combination is to get a passive thunderbolt 4 cable of 1 meter or less.

And you may have noticed that thunderbolt cables are really stiff and heavy, because of these 20 wires inside it. Someone who just want to charge it's smartphone/laptop will prefer a cheaper and lighter usb C cable with only the 4 wires needed for this use case.

My grandparents never could get to grips with modern technology, and I remember a time my granny asked me if I thought there would come a time when technology became too complex for me to understand. Obviously I said no and put it down to living in a different time. USB naming conventions have me worried for my future in which I can't figure out if the charger in my hand is USB GEN 3 PD 6.0.3 third edition GaN backwards compatible 240v AC 4K Pro is the one for my electric toothbrush, or the other one over there which looks the same but might blow my house up.

I couldn't even explain to her why it didn't work in the thunderbolt port, just that it was that way.

It seams like the easy solution for USB's nonsense naming scheme is to just separate them into 2 tiers. "USB 4" for the required set of capabilities, and something like "USB+" or "Ultra USB" for the set of required AND optional capabilities. That way there's no confusion as to how any of this works for the consumer, and there's only two naming schemes you have to know.

well, except that the +/Ultra one would need to then include the actual information regarding what it does and does not do. Arguably it would make more sense to have have some system of indicators (preferably just words written on the dratted thing, if they could be made to not wear off) marking which features the thing did and did not have. Starting with the fact that it's Actually a USB 4 cable, because unlike A and B (and by extention the mini and micro plugs, because they always had an A on the other end), C plugs Don't even indicate which USB standard they comply with, nevermind any variants and the like. USB 3 C to C cables already have this problem (or would if anyone made C to C cables for anything but the last version of the USB 3 standard).

Or 2 badge of high-speed and PD separately. So that if you see USB [hs4] [pd4], stop using usb 4.0 for consumers. Then if you want to use your ssd, check if you got that USB HS4 badge. If you want to charge your laptop, look for the PD4 badge. If you want to use your 5k oled 1000 nits monitor, make sure your port has both HS4 & PD4. This is also good for future versions. Say for example the lowest tier USB 6 already requires 100Gbps, but still doesn't make sense to require your laptop's USB6 port to output 200W. Instead of telling people all USB6 are faster than USB4 Pro, but don't necessarily have the same charging power. You just tell them, it's HS6 PD3, so you look at your power hungry 4k monitor, sees HS5 PD4, you know you need something better

If features are most likely optional for USB4 because of mobile, they should have just made USB4-standard and USB4-mobile with the mobile version not having any of the optional features that mobile devices can't utilize. That then keeps things easy and simple for the consumer, as they know if they are buying USB4-standard it's got all the optional features and of course works with mobile devices as well. But if they just need a USB4 cable for their phone they can buy the slightly cheaper "USB4-mobile" cable.

I have a 1m active 100w TB3 cable from cable matters and it works with ASUS external GPU which shipped with a 0.3m passive TB3 cable, the latency was slightly worse with the active cable. Disabling the iGPU can help with eGPU latency. This is especially true with the Skull Canyon NUC as the 6770hq has 128mb on-package level 4 cache split 64mb/64mb iGPU and CPU. When iGPU is disabled, this large L4 cache gets reallocated entirely to the CPU. The larger the Cache, the better for latency when it comes to eGPU's.

For laptops this might a great solution if you want to upgrade your graphics card or something, but most of those features are not used a lot by "normal" PC users, and as far I can see it's also very expensive. I guess I would have the opportunity to add a PCIe card with USB4, but I can't use my second PCIe slot anymore because my graphics card is so huge that it stands in its way, and my graphics card is way more important for me than USB4 slots

right now the same USB C port is shared amongst so many different types of connection. Problem is most manufacturers will go for the basic implementation and finding out what you actually get is gonna be hard, especially before you buy. Cables are already and will be an even bigger mess in the future too. How am I supposed to remember if a port supports somehing or not? What about cables? Most USB C cables around are just USB 2.0 with new connectors... I understand implementing a very flexible port like USB C would be very hard to do in a neat and tidy way, but this is just gone nuts. A "do it all" connector will just end up in "do nothing at all". Stop giving so much choice to manufacturers, and a different implementation REQUIRES a different name at least and a differently colored port. Every USB C should at least reach 10Gbps and you call it USB 4.0 with black port coloring. Does it supports display? Call it 4.1 and give it a green color. Does it support pcie aswell? 4.2 and another color. Let's not even talk about the different tunneled and alternate modes. This is utter crap.

After watching the video, for any future use of USB-C port, we need to check all spec of the host machine (e.g. the PC end), the cable, and the device, which is impossible to get since customer service don't know what the hell you are asking, and there may be no manual include this information, especially the cable. I would say that we will need a USB-C checker device to find out what we really have, like what is supported and what is not. Also I hope LTT should include laptop review/promotions with such information for us.

The standard is quite consistent. It states what and how should be done. This way if something supports PCIe over USB-C, it meets the standard and is compatible with anything else that has PCIe over USB-C. That's the way we should be thinking now. It's not just a USB feature. It's a feature that can run over USB connector. The standard should not be used by marketing and that's what USB-IF was fighting with for quite some time. People are just stubborn and will not stop marketing stuff as USBX. Stop doing that! If it has 20Gbps, that's what you put on it! There's a logo for that, use it!
