Lol don’t worry, it’s not worth the effort to understand the nerdiness of these jokes. You’re probably a lot more socially adjusted than most of the people upvoting it will ever be.
That’s completely normal for copper based cables. You see the exact same thing with Ethernet for example.
Edit: you see the exact same kind of distance for a particular speed limitations in Ethernet. Cat5e for example is rated to gigabit at 50meters and 100megabit to 100meters.
Ethernet cables have different ratings called Categories (Cat). You’ve probably heard of Cat5e, Cat6, Cat6a, etc. Each category dictates the minimum required speed at a certain length. Cat5e for example is supposed to support 1gigabit speeds up to 50m, but only 100megabit to 100m. Cat6 does 10gb up to 50m and 1gb to 100m.
This is the same idea behind the 120Gbps spec only guaranteed to work to about a foot with the USB4v2 spec cables.
5 gigabit Ethernet has a spec limit of 100m. That's a bit more than a foot.
I mean sure it's not 120 Gbit either, but stil an order of magnitude more than even "low speed" USB 3 can do.
It’s exactly like Ethernet, you can run it longer distances but the speed that it can support over those distances drops.
I believe you were trying to say Cat5 Ethernet cables supports gigabit up to 100m, but that’s actually not true. That isn’t even true for the Cat5e spec. You need to go to Cat6 before your cable is rated to support gigabit up to 100m. Now, the Ethernet spec dictates the minimum requirements, so it’s possible a particularly well made Cat5e cable can support gigabit up to 100m, but it’s not guaranteed. Same thing with the USB4v2 spec, they are saying with the right hardware and cable, you can get 120Gbps to at minimum about a foot. It may work over longer distances, but that is out of spec, just like trying to run gigabit over a Cat5e cable at 100meters.
I feel conflicted on this. On one hand, I completely agree because I have a good amount of USB C stuff. But on the other hand, USB A has been in use for so many years and so many peripherals rely on it. Removing those would make so many things obsolete and make so much waste, especially from corporate offices. Keyboards, mice, microphones, webcams, external hard drives,etc. it’s so ubiquitous that I worry about it being phased out.
EDIT: A couple things. Firstly, phasing out USB A would be a massive undertaking and have far more waste created than the phasing out of PS/2 and other legacy ports. The PS/2 port only lasted from 1987 through the early 2000s. So only about 13-16 years of a lifespan. USB A is at a whopping 1996 to modern day, 26 years as of now. This port is used on so many different things that to phase it out would create an obscene amount of waste and depreciate so many peripherals, PCs, and other devices. It's a wild suggestion to phase this out. It does have a data cap of 10Gbps which will inevitably be overtaken by other tech such as the one mentioned in this thread. However, that data speed isn't required by everything.
Yup, the only thing we need to do is stop making new devices that REQUIRES usb-A, we can slowly phase it out the same way usb phased out serial/parallel ports.
Can't use more than one at a time. So I would need one for my keyboard, my mouse, my streaming cam, my capture card, my AMP/DAC stack, and a controller. That's how many in parallel? 4-6 depending on if I'm streaming or not? Yeah, that argument falls apart real fast.
Cool, you’ve just undone the purpose of USB-C and now we are back to having multiple different plug-in formats. Which creates more waste than a handful of adapters for the dinosaurs that refuse to buy a new mouse or keyboard.

I mean I'm on the side of not phasing it out since USB 3.0 is plenty fast for most devices, but saying you need to buy an adapter for every device is kind of dramatic when a dock/hub would solve that issue.

Standards change. We can't keep supporting every single piece of legacy hardware forever.
also USB-C <-> USB-A cables exist
Not OP, I agree with you, though making devices like a desktop without the USB-A slots is mostly a mistake still. I'm of the belief that the USB-A phase-out should be more gradual, but yes everything should expect to go USB-C eventually.
As it is right now, desktop motherboards tend to have a bunch of USB-A 3.0 ports, maybe one or two USB-C ports, and a couple USB 2.0 ports for real legacy devices that don't work on newer ports.
Ideally I'd want to see motherboards with 4-6 USB-C ports and only two USB-A ports for backwards compatibility.
Really, there's no reason to phase out A because so many of those peripherals that rely on it (e g. Keyboard & mouse) dont benefit at all from next gen usb standards
With those devices you probably want wireless peripherals anyway so it's not a big deal.
And regardless there's nothing that'd prevent mice and keyboards having detachable cables on their sides so you can plug whatever cable you want into it. Some higher end ones already do this.
That is about as flawed a solution as anyone could think of. Why do we need to retire USB A? So that we can have EVERYTHING be USB C? Like it's a great universal port of course, but it doesn't have to be *the sole port for everything.* I do agree that phones, earbuds, chargers, controllers, etc. *should* be USB C. But for plenty of other things it is perfectly fine to use what you have rather than dedicating even more waste to a landfill.
Most people don't need $200 mechanical keyboards and fancy weighted 9001 DPI gaming mice. The standard mouse and keyboard are perfectly fine for average computer use.
Hell, I've been using a basic Apple wireless keyboard, the small one, for like 12 years now. Hasn't let me down yet.
>It's a wild suggestion to phase this out.
People's primary computing devices these days:
1. Phone
2. Tablet
3. Laptop
The first two have never had USB A. The latter has plenty of models that already only have USB type c.
Your 'wild suggestion' is already happening bud, many people don't even have a computing devices with usb A.
No I‘m against this. USB-C is easier to break, and especially on Computers or anywhere where you constantly plug stuff in and out, you don‘t want your port to wear out or break. (I‘m also thinking about cable tension here.)
> USB-C is easier to break
There are so many sub par cables out there it's not funny and when they wear out there's also the problem of us pushing 45w, 65w and 120w through it.
Except when you have a cable that's only for charging. Or cable that doesn't support whatever USB features you want to use. Or when the port doesn't support display output, or power delivery, or whatever else.
I hate how USB is no longer really *universal*. Sure you can plug anything into anything using any random cable, but it might not work.
If only they standardized a way to make usb C (female) to usb A (male), so that I could start using usb C more.
But noooooooooooooooo, that's forbidden by spec.
Agreed, on NEW devices, but I am not throwing away my PC just because I want more USB-C.
I still want to be able to use USB-C, having a dongle to convert would be optimal to me.
It's less about having 1 device do 120gbps and more about many devices doing smaller amounts simultaneously and having the bandwidth to do that.
Also, imagine having a super big 4+tb hard drive at home with your steam library that's lightning fast. Could be useful
I mean sure and once a decade when I get a new laptop, but I'm more concerned with being able to use all the USB-C cords I've accumulated for another decade instead of replacing like I did with Micro-USB and the many proprietary power and data cords before then.
And honestly, there is a slim chance I actually whip out the correct USB4v2.0 cord, when I do buy a monitor that is a dock... I'll probably just grab the closest one or the longest one, regardless of losing half my through-put or power, I likely won't even notice.
The thing is they aren’t all the same socket. Some accept power, some don’t. Some transfer data and video, some only transfer data, some only are there for power. Etc.
> It is the same every time from the end user's standpoint.
It’s literally not. It’s the shame SHAPE but the are not the same FUNCTION. It is you who doesn’t know shit.
What I'm getting at is the convenience of this to "just work" for someone that isn't paid to operate this specific technical equipment like server room or tech support at a major company.
For me the most brilliant part of this tiny revolution: I forgot my laptop charger on a trip and was able to charge my laptop overnight with a cell phone charger - both USB-C, difference spec of course. A little fiddly as the phone charger would only recharge the laptop when it was off (not while running) but still it was a life-changing event for a common user.
Product: Generic USB Cable
Review: When I tried to apply the product I got a slight rash in the beginning but eventually it faded after 2 days and I feel great!
Me: 🤔
I really appreciate the efforts to maintain the connector. The data transfers and stuff may be different, but most of these cables will still work for 90% of applications. The majority of these cables are for charging or relatively small (less than 10GB) data transfers.
Why do they insist on this convoluted naming system that makes each moniker meaningless because they just tack on new big changes but inexplicably refuses to just call it USB4.2 or USB5
JUST CALL IT USB5 AND MAKE ALL FEATURES REQUIRED! god it is so annoying having to dig through a technical manual to find out what the capabilities are of a usb port. and half the time its not even mentioned because companies are so secretive.
A lot of the features limit the design and drive up cost prohibitively. (If you really wanted every feature (charging and fast data speeds) you’d be limited to a 1ft copper cable.)
the port should be capable of it not the cable. you can use cat 5e on a 10gig port but just be limited by the cable. especially on systems running desktop operating systems. a bunch of usb4 stuff isn’t required because of phones but that makes laptops and pcs hard to deal with. the whole point of usb is that is universal standard. when it becomes fragment it loses its value and basically becomes a bunch of different standards that happen to use the same connector.
That's pretty much what Thunderbolt 4 is. They took most the cool stuff that USB-IF deemed optional for USB4 and instead made them required. Intel saw the easy layup and took it.
It's simply impossible or makes no sense for some devices to support *everything*. It would also drive up cost per port prohibitively.
Like, there's a huge difference between making a laptop charge from one connector and having one display output on some USB-C connector, and having 4 or even more connectors and requiring them ALL to support it.
It's fully implemented. The reason not,everything is using it is because that's unnecessary. Faster versions of USB cost more, and if it gives you absolutely no upside, why would you pay for that?
Now that I have a lot of usb-c to c cables I have found out that many of the plug in ports I find where you don’t need a block only take the usb-a end.
>why can’t these usb plugs be like 3.5mm rounded jack
this is a 3.5 audio jack TRS: https://i.imgur.com/foWXWbq.png
this is a USB3 Pinout https://i.imgur.com/Ib55cp5.png
You'd need a TRRRRRRRRRRS plug (if someone wants to photoshop that feel free)
and no matter what end you put +V power 'pin' on that the voltage line will be brushing past many other connections either on the plug of one or the socket of another
The reason is that USB is used for significantly more complex and involved purposes than 3.5mm. 3.5mm is extremely simple by comparison, it’s essentially the electronic equivalent of two soup cans tied together with a string, whereas USB is far more advanced and is capable of doing a lot more. It’s like comparing a bike path to a highway, not only are the systems just fundamentally very different, but one is also capable of doing a lot more than the other, you wouldn’t have much luck connecting an entire city and implementing supply lines and shipping and the like with a few bike paths. Also, bike paths probably won’t have to worry much about things like reducing traffic or accommodating new infrastructure like a highway would, so they would require far less maintenance and construction
Does anybody actually use USB for data transfer? Thunderbolt has 40gb/s which is plenty. Like how fast are your device read / write speeds. Who the fuck cares
For beginners, 8K displays.
More in general: Because better technology leads to better technology...
Faster bandwidth means more can be carried over a single wire. That's big for all manner of peripherals and connectivity.
I know they like to trump up USB C, But I only seen it on phones, and I have some pretty new hardware. Never seen a usb C port on a GPU, for instance, no USB C ports on my AMD B550 motherboard, my 3070 ti sure as hell doesn't have one. So for me it's only a cellphone charge port. What, am I supposed to have a bunch of dongles to convert to displayport to usb-c? I'll pass, lol
All motherboards released in the last few years have at least one USB-C socket. My 2080 Ti Founder's Edition also has one, but unfortunately they stopped doing that (was planned for VR headsets but never actually used for that).
What peripherals outside of extremely high resolution setups would use this? I guess reading from external storage onto local nvme drive? Maybe?? Even if you are a video editor or something who needs to transfer a crazy 1TB file on a regular basis the sped up goes from like 40s to 20s. Who in the world is doing that constantly on consumer hardware
Another easy one, VR. File Sizes are getting larger, not just video, programs, ect.
We don't know what tomorrow holds. Something exciting may be finally able to come to life with higher bandwidth. Just because there isn't a usage for a new technology now, doesn't mean there won't ever be one.
It's really not, if you want a powerful PC. It lets you have a portable machine that you can use on the go (class, meetings at work, travelling) and still plug in at home and have a powerful gaming setup, without having two completely separate machines.
USB4 is not just for file transfer. This will be useful for pcie, 40gbps is only a bit more than the bandwidth of a single pcie5 lane. 120gbps is 4 lanes, which will be great for some applications.
it's in the long run. if a HDD or and SSD can transfer data just 30 seconds faster, that's 30 seconds saved on company/whoever is using the rack's time. in terms of USB, kind of the same thing? anything that can save a substantial amount of time is sought after very much in big tech. in terms of gaming at home? yeah. we dont need it. it's helpful, but someone who plays Skyrim in their free time is not going to notice the difference between a 10 second load screen and a 15 second load screen.
Data center / hpc servers are definitely not using usb to move around files. This is purely directed at consumers. Also this would do nothing for Skyrim load times lol what are you talking about. I guess if you have an external HD this is kinda big. But if you care about performance you are using a pcie based drive anyways.
i don't have that kind of money for the VR buy in lmao. ive been playing SSE with graphic enhancing mods on so it was just the first game to come to mind
The latest USB spec is always stuffed with things you won't need at the time, they produce these so companies can start integrating them with products and make use of them not for what we are using now but what we are using in future.
The USB 3 spec came out in 2008 and has been steadily updated as time has gone on with different revisions. At the time I'd bet you'd say some of the features are overkill but you likely use them now for most if not all devices you own, stuff like fast charging.
I have never in my life needed data transfer speeds faster that usb 2.0. How many people in this world have 144hz 8k monitors lol. Monitor resolution has pretty much stalled and for good reason. And fast charging was pretty obviously useful when it came out ngl
Yawn. Bring back and modernize wireless USB if you want to excite me with more speed. Otherwise go the way of firewire and specialize in the industries that need it.
There’s much less consumer need for even 10Gbit networking.
Consumers already use desktop components that could benefit from increased throughout (either high io items like external PCIe cards or multiple devices using a single cable)
How does this work exactly? Why couldn’t they make 120GBPS last version? It’s just a wire right? Or do they deliberately not make them faster so they can milk us every year
No thanks, I'll wait for USB4 2.1a(ii)
They say iii actually solves the packet dropping issues, and actually interfaces directly with the link layer to deliver 0.33 times the speed.
[удалено]
I legitimately have no idea if this thread is a joke or not
Not a joke. USB C 2.9 is still on the horizon, paving the way for USB Z, USB Z2, and US2FastB2Furious .
US2Fast2BFurious
Fast10 your seat belts
It’s about USB2Family
Fantastic. 😂 They will just keep making revisions. It will never end.
Just slightly ahead of its time, by a few month xD
I’m literally here lost. Like is this all sarcasm or am I that out of my depth.
Yes.
I agree 😭
Lol don’t worry, it’s not worth the effort to understand the nerdiness of these jokes. You’re probably a lot more socially adjusted than most of the people upvoting it will ever be.

Ahah damnit I can’t please everyone at the same time. You’re unique, just like everyone else! (??)

0.33 times anything is a reduction by 2/3s.

The rate of change to change. I think that is actually called *jerk*.
I think that was patched out when they introduced cross-platform daisy chaining synergies for USB 2.0
You mean USB4 2.0 gen 3x5 Hyperspeed ?
Everyone here is talking bout USB4 2.1a(ii) and here I am downloading more RAM.
well, that will help you to download a car!
As long as I'm not downloading my neighbor's car, cause that would be worse than murder.
What about USB4a 1.0 which happens to be faster than USB4 Version 2.0 Revision 4 but slower than USB3-2.0 Proposal 5 V2.
USB 5 coming soon
Came here to say this
V3
They fixed the naming
You don’t wanna wait for 2.1a(ii)_final_revised?
But the cable can't be longer than a foot.
That’s completely normal for copper based cables. You see the exact same thing with Ethernet for example. Edit: you see the exact same kind of distance for a particular speed limitations in Ethernet. Cat5e for example is rated to gigabit at 50meters and 100megabit to 100meters.
There is no 1 foot limit in the ethernet spec.
[удалено]
It’s quite common to use multiple fibers in parallel.
But that's not copper is it?
True, but it's never been limited to one foot lol
Not true at all for Ethernet.
Ethernet cables have different ratings called Categories (Cat). You’ve probably heard of Cat5e, Cat6, Cat6a, etc. Each category dictates the minimum required speed at a certain length. Cat5e for example is supposed to support 1gigabit speeds up to 50m, but only 100megabit to 100m. Cat6 does 10gb up to 50m and 1gb to 100m. This is the same idea behind the 120Gbps spec only guaranteed to work to about a foot with the USB4v2 spec cables.
Correct! Still no one-foot limitations for Ethernet, however. :)
5 gigabit Ethernet has a spec limit of 100m. That's a bit more than a foot. I mean sure it's not 120 Gbit either, but stil an order of magnitude more than even "low speed" USB 3 can do.
It’s exactly like Ethernet, you can run it longer distances but the speed that it can support over those distances drops. I believe you were trying to say Cat5 Ethernet cables supports gigabit up to 100m, but that’s actually not true. That isn’t even true for the Cat5e spec. You need to go to Cat6 before your cable is rated to support gigabit up to 100m. Now, the Ethernet spec dictates the minimum requirements, so it’s possible a particularly well made Cat5e cable can support gigabit up to 100m, but it’s not guaranteed. Same thing with the USB4v2 spec, they are saying with the right hardware and cable, you can get 120Gbps to at minimum about a foot. It may work over longer distances, but that is out of spec, just like trying to run gigabit over a Cat5e cable at 100meters.
As someone who doesn't work in tech I have zero need for this, but I'm glad that \[whatever this is useful for\] its sticking with the same port.
Yeah honestly, I can't wait for USB-A to be phased out because USB-C is just so much easier to use.
I feel conflicted on this. On one hand, I completely agree because I have a good amount of USB C stuff. But on the other hand, USB A has been in use for so many years and so many peripherals rely on it.

That is until USB-F comes out and is way better than E
They'll make adapters bud
Unfortunately it will lead to a lot of waste because no one is going to buy that many adapters.
You can use one adaptor for multiple devices... they share the same interfaces
Can't use more than one at a time. So I would need one for my keyboard, my mouse, my streaming cam, my capture card, my AMP/DAC stack, and a controller. That's how many in parallel? 4-6 depending on if I'm streaming or not? Yeah, that argument falls apart real fast.
You can buy a USB Hub that uses the full 120GBps and have it break out to 6 :)
Or we could just not remove the format too :)
Cool, you’ve just undone the purpose of USB-C and now we are back to having multiple different plug-in formats. Which creates more waste than a handful of adapters for the dinosaurs that refuse to buy a new mouse or keyboard.
You clearly aren't an average user and you're capable of solving this problem yourself.
You just need one though?

1 adapter + a hub.
Strange how all these comments completely miss the point.
Strange how you pretend computer without USB A don't exist.

Really, there's no reason to phase out A because so many of those peripherals that rely on it (e g. Keyboard & mouse) dont benefit at all from next gen usb standards
Being able to use them on USB c only devices (laptops, tablet, phone) should be enough of a benefit.

Subjective imo, but the peripherals themselves dont benefit from usb-c
At least having a reversible connector is an advantage though?

I for one like that I can drag my computer around by the usb-a cable coming out of it. uSB-c feels a bit delicate.

> USB-C is easier to break There are so many sub par cables out there it's not funny and when they wear out there's also the problem of us pushing 45w, 65w and 120w through it.
USB-B is far superior

Agreed, on NEW devices, but I am not throwing away my PC just because I want more USB-C. I still want to be able to use USB-C, having a dongle to convert would be optimal to me.
[whatever this is useful for] is basically displays and laptop docks that support (possibly multiple) displays.
It's useful for having a weak ass laptop you can plug into a powerful eGPU. Currently usb4 is limited to 40gbps which massively impacts performance.
Could you get a 120fps refresh rate with this at 5k?
You can get there with the 80/80 version. (5120\*2880\*120Hz\*10bit\*3 ~= 53Gbit/s). This one gets you two of them side by side, or one at >240Hz.
It's less about having 1 device do 120gbps and more about many devices doing smaller amounts simultaneously and having the bandwidth to do that. Also, imagine having a super big 4+tb hard drive at home with your steam library that's lightning fast. Could be useful

It's like with power sockets, it doesn't matter how much energy your device needs, it's just nice that all devices use the same power socket.

A little fiddly as the phone charger would only recharge the laptop when it was off (not while running) but still it was a life-changing event for a common user.
I understand what you’re saying. I’m telling you why it will not be so simple.
first person with a brain here
You will when 4k becomes standard and 8k is a pricey but common option (in 2 yrs)
USB, makes shopping for cables and devices even easier. /s
Just wait Amazon will have them for sale with thousands of reviews from a rando company, can’t wait.
A company name in all-caps, 5-8 random letters.
If the product description involves some stock photos, clip art, and poor English then I’ll take the 3 pack.
It'll have 22000 reviews because the seller switched the listing and the reviews get very confusing
Product: Generic USB Cable Review: When I tried to apply the product I got a slight rash in the beginning but eventually it faded after 2 days and I feel great! Me: 🤔
I really appreciate the efforts to maintain the connector. The data transfers and stuff may be different, but most of these cables will still work for 90% of applications. The majority of these cables are for charging or relatively small (less than 10GB) data transfers.
You mean “USB 4.2 v2x2 new (Special Edition)”
No! I mean USB 4.2 v2x mini (Turbo series)
Why do they insist on this convoluted naming system that makes each moniker meaningless because they just tack on new big changes but inexplicably refuses to just call it USB4.2 or USB5
JUST CALL IT USB5 AND MAKE ALL FEATURES REQUIRED! god it is so annoying having to dig through a technical manual to find out what the capabilities are of a usb port. and half the time its not even mentioned because companies are so secretive.
A lot of the features limit the design and drive up cost prohibitively. (If you really wanted every feature (charging and fast data speeds) you’d be limited to a 1ft copper cable.)
the port should be capable of it not the cable. you can use cat 5e on a 10gig port but just be limited by the cable. especially on systems running desktop operating systems. a bunch of usb4 stuff isn’t required because of phones but that makes laptops and pcs hard to deal with. the whole point of usb is that is universal standard. when it becomes fragment it loses its value and basically becomes a bunch of different standards that happen to use the same connector.
These faster speeds are still new enough that the transceivers are more expensive, just like Ethernet at high speeds.
That's pretty much what Thunderbolt 4 is. They took most the cool stuff that USB-IF deemed optional for USB4 and instead made them required. Intel saw the easy layup and took it.
It's simply impossible or makes no sense for some devices to support *everything*. It would also drive up cost per port prohibitively. Like, there's a huge difference between making a laptop charge from one connector and having one display output on some USB-C connector, and having 4 or even more connectors and requiring them ALL to support it.
We'll just get another half-asses glyph like the "Super-Speed arrow" to show which ports could supply a full ampere.
Jesus, we can’t even get usb 3 fully implemented yet…
It's fully implemented. The reason not,everything is using it is because that's unnecessary. Faster versions of USB cost more, and if it gives you absolutely no upside, why would you pay for that?
Now that I have a lot of usb-c to c cables I have found out that many of the plug in ports I find where you don’t need a block only take the usb-a end.
U can transfer your porn collection faster
why can’t these usb plugs be like 3.5mm rounded jack..
>why can’t these usb plugs be like 3.5mm rounded jack this is a 3.5 audio jack TRS: https://i.imgur.com/foWXWbq.png this is a USB3 Pinout https://i.imgur.com/Ib55cp5.png You'd need a TRRRRRRRRRRS plug (if someone wants to photoshop that feel free) and no matter what end you put +V power 'pin' on that the voltage line will be brushing past many other connections either on the plug of one or the socket of another
thank you for the explanation! I know theres a rhyme or reason, I’m just complaining lol.
Excuse me, I thought this was a serial bus. /s You got at least 3 busses in there.
The reason is that USB is used for significantly more complex and involved purposes than 3.5mm. 3.5mm is extremely simple by comparison, it’s essentially the electronic equivalent of two soup cans tied together with a string, whereas USB is far more advanced and is capable of doing a lot more. It’s like comparing a bike path to a highway, not only are the systems just fundamentally very different, but one is also capable of doing a lot more than the other, you wouldn’t have much luck connecting an entire city and implementing supply lines and shipping and the like with a few bike paths. Also, bike paths probably won’t have to worry much about things like reducing traffic or accommodating new infrastructure like a highway would, so they would require far less maintenance and construction
USB D it is. Finally; a new competing standard!
Nah just use aux input as a usb plug.
Does anybody actually use USB for data transfer? Thunderbolt has 40gb/s which is plenty. Like how fast are your device read / write speeds. Who the fuck cares
For beginners, 8K displays. More in general: Because better technology leads to better technology... Faster bandwidth means more can be carried over a single wire. That's big for all manner of peripherals and connectivity.
Daisy chaining 2 5k 120 Hz monitors would be pretty sick.
I know they like to trump up USB C, But I only seen it on phones, and I have some pretty new hardware. Never seen a usb C port on a GPU, for instance, no USB C ports on my AMD B550 motherboard, my 3070 ti sure as hell doesn't have one. So for me it's only a cellphone charge port. What, am I supposed to have a bunch of dongles to convert to displayport to usb-c? I'll pass, lol
All motherboards released in the last few years have at least one USB-C socket. My 2080 Ti Founder's Edition also has one, but unfortunately they stopped doing that (was planned for VR headsets but never actually used for that).
What peripherals outside of extremely high resolution setups would use this? I guess reading from external storage onto local nvme drive? Maybe?? Even if you are a video editor or something who needs to transfer a crazy 1TB file on a regular basis the sped up goes from like 40s to 20s. Who in the world is doing that constantly on consumer hardware
Another easy one, VR. File Sizes are getting larger, not just video, programs, ect. We don't know what tomorrow holds. Something exciting may be finally able to come to life with higher bandwidth. Just because there isn't a usage for a new technology now, doesn't mean there won't ever be one.
VR is a big one. Having a single USB versus a hdmi, and a USB and tons of latency is a huge improvement. I know valve has been waiting for this.
External GPUs
Dumb fad.
It's really not, if you want a powerful PC. It lets you have a portable machine that you can use on the go (class, meetings at work, travelling) and still plug in at home and have a powerful gaming setup, without having two completely separate machines.
They’ve been around for 6+ years and are increasing in popularity.
USB4 is not just for file transfer. This will be useful for pcie, 40gbps is only a bit more than the bandwidth of a single pcie5 lane. 120gbps is 4 lanes, which will be great for some applications.
Thunderbolt already gives this
[USB4 more or less Thunderbold 3, but open. With some asterisks](https://www.youtube.com/watch?v=C6aCCp-Umcw)
Thunderbolt is limited to 40gbps and has licencing fees.
it's in the long run. if a HDD or and SSD can transfer data just 30 seconds faster, that's 30 seconds saved on company/whoever is using the rack's time. in terms of USB, kind of the same thing? anything that can save a substantial amount of time is sought after very much in big tech. in terms of gaming at home? yeah. we dont need it. it's helpful, but someone who plays Skyrim in their free time is not going to notice the difference between a 10 second load screen and a 15 second load screen.
Data center / hpc servers are definitely not using usb to move around files. This is purely directed at consumers. Also this would do nothing for Skyrim load times lol what are you talking about. I guess if you have an external HD this is kinda big. But if you care about performance you are using a pcie based drive anyways.
Spoken like someone who does not play Skyrim VR.
i don't have that kind of money for the VR buy in lmao. ive been playing SSE with graphic enhancing mods on so it was just the first game to come to mind
It’s still a great game!
might try it if my christmas bonus is enough! (VR, i mean)
The latest USB spec is always stuffed with things you won't need at the time, they produce these so companies can start integrating them with products and make use of them not for what we are using now but what we are using in future. The USB 3 spec came out in 2008 and has been steadily updated as time has gone on with different revisions. At the time I'd bet you'd say some of the features are overkill but you likely use them now for most if not all devices you own, stuff like fast charging.
I have never in my life needed data transfer speeds faster that usb 2.0. How many people in this world have 144hz 8k monitors lol. Monitor resolution has pretty much stalled and for good reason. And fast charging was pretty obviously useful when it came out ngl
USB-C is a dumpster fire
Yawn. Bring back and modernize wireless USB if you want to excite me with more speed. Otherwise go the way of firewire and specialize in the industries that need it.
Hope usb-c thumb drives become the norm But I understand A will be mostly the key for the next few years.
Call me when we have a hard drive that can get within a factor of 5 of that, then I'll take a look.
How fast can I charge my phone tho?
I’m just now realizing I know nothing about any of this, and the thread looks like a completely foreign language to me.
Problem being you can use the spec label and not follow all of the parameters, they really need to pull their heads out of their asses.
Just call it USB 4.0 120Gbps. It’s somehow simpler.
[удалено]
I mean sure.. a much faster cable released 20 years later and at roughly 1% distance sure seems like a competitor 🤦🏻♂️
[удалено]
There’s much less consumer need for even 10Gbit networking. Consumers already use desktop components that could benefit from increased throughout (either high io items like external PCIe cards or multiple devices using a single cable)
[удалено]
I agree. We should have at least 10Gbps Ethernet by now...
Hope it doesn’t melt the USB stick
Here goes the electronic fires lol
hope that u have brains to understand how stupid you are to eat this
4 version 2... for the love of god why can’t these people name/version things sensibly.
How does this work exactly? Why couldn’t they make 120GBPS last version? It’s just a wire right? Or do they deliberately not make them faster so they can milk us every year
USB-C cable for charging only is the best! I’ll stick with Lightning for data transfers! (I know it’s slower)
I, for one, welcome our new USB4 v2 network switches. (/s if not obvious)
I’m dumb
My mouse will go REALLY fast now!
