You have to wait a little more to know USB4 all specifications. As will be coming soon, and after which we all are able, to watch little changes that will surely make our lives easier and simple. If you are looking for the official USB4 specification release date then my friend you have to wait until mid-2019, and there is no problem because we have already known very much about the USB4 specification. Just take a look at USB4 changes and what makes USB4 different from the previous USB 3.0. And what these changes will make a difference.
USB 4.0 – Fast Data Transfer Rate
One of the unique point about the USB 4.0 full specification is “two-lane functioning using present USB Type-C cables and up to 40 Gb per second operation over 40 Gbps certified cables.” We have seen several companies advertising “SuperSpeed USB” fast data transfer rates ever before but at present, they are all bounded to USB3 specifications and the maximum of data transfer, is 20GB per second (Gbps). But now, the data transfer speed will be 40Gbps which is double the present data transfer speed, or you can say double the speed of the current fastest data transfer speed.
But the most important, factor this can only be done if, all the connected chains, both the devices, connection cable and any type of hubs, are supported with USB 4.0. And one thing more, all those cables are to be USB-C cables, so this will also finish the use of old-style USB-A interface.
USB 4 – Secure Way To Transfer Data
USB 4 will also provide you more data and display procedure, so you can easily take advantage of fast data transfer rate.
Depending on this, the data is only data, a stream of ones and zeros that a microprocessor can transform into something that talks with us. But it is completely complex than it is when you think that there are so many different types of data and specifically it is just a stream of ones and zero. You have things like a signal that indicates a screen what to display, or a file is being transferred, or network data too. As long as it is a supported protocol, you can send almost anything to the USB.
As USB 4 supports much more data protocols, and it will open several types of devices of data transfer. The USB Implementers Forum is a non-profit organization and the main activity, perform by USB-IF, is the promotion and marketing of USB, Wireless USB, USB. Now USB-IF has informed that new USB 4.0 will be able to handle various data protocols that can transfer the bandwidth all over the bus. Which is directly indicating that from now onwards, we will able send and share a 4K HDR signal with a USB cable and we can also use the same cable for sharing and transferring a data file or use as a connection to a Wi-Fi interface.
It will definitely, make a huge impact on the utility and performance of USB hubs and heavy devices, such as PC or laptop motherboards where control of activity is manager by USB controller for several user interfaces. Depending on the context, all of us now has to wait and watch to know how exactly, a 40Gbps connection manages the tasks we drive at it.
USB 4.0 – Support Thunderbolt 3
If you ask me about the major, best and important changes, made to the USB specification, then my answer will be the best and biggest specification changes to USB is the inclusion of Thunderbolt 3 support.
Intel had already started to certify the devices which support for Thunderbolt 3 in 2015 and also continued in 2017 it had also, decided to open the standard. This means that any other company that genuinely required to execute Thunderbolt would have to pay very less amount of license fee to be fully compatible.
Users with USB 4, already have in-built Thunderbolt, which directly indicates, that amazing specifications and features are now available at a very less price for device makers to hold, 100 watts of power supply, the fast 40Gbps data transfer rates, and also supports for eight lanes of DisplayPort data which shows that two 4K HDR displays at 60 Hz or one 5K display are completely supported.
You would be happy to know that, Thunderbolt 3’s technology is presently open and royalty-free, any device that will have benefit from it will be little less expensive and there is very big chance to exist in the foremost place. This not only supports limited devices like PC boards, or it will find in a computer or tablet, but it also supports devices such as devices like displays and external GPU boxes. Now, companies have to pay Intel a little amount of license fee rather than giving a particular portion of their profits, so they will show more enthusiasm to develop things that are great.
USB 4 – Odds and Ends
Yes, USB4 is not USB 4.0. A USB-IF is weird when we actually look at USB 3.0 (which is actually USB 3.1 Gen. 1) or USB 3.2 (USB 3.2 Gen. 2×2). At present, we have not a small idea of what the first implementation of the news will be called to the USB4 standards and it will not be published until mid-2019.
The best part about the USB4 is that it will also support all USB specifications and all the previous Thunderbolt 3 version devices. But we also want that, it will support older USB standards, but total compatibility with Thunderbolt 3 devices is a huge deal. It directly indicates that all those costly devices and cables you have already purchased will work with USB4, fine.
Talk to cables, then you will need a compliant cable to get any benefit from any of these. Pay attention I said complaint and not certified, a producer can get a device certified (including cable), but it is completely maintained without payment. That also indicates it is random choice and certification has no genuine value. There is no such thing that certified devices and cables are better than non-certified devices and cable. Non-Certified devices and cables can perform better than certified devices and cables.
USB4 – Releasing Date
USB4 have no interlinking and any impact with anything you buy in this year 2019. The official date is not yet clear but it will definatly become official until the mid-2019 and simply means that the device you want to purchase would not have it included until before 2020. After this, you will preferably buy a desktop, laptop, and even tablets or smartphones which will have the ability to support USB4. But nothing to add to it with the standard supports no genuine advantage.
When USB-C has arrived, it also brought the same framework. We first saw the devices using the new connector, although they were not completely compliant. Those devices had the advantage of the new connector, but the things you plug on the other end of the cable were not easily available until later. In some cases- especially when it comes to power distribution systems, previous devices were not in line with today’s standard and do not offer any actual way of fast charging or bi-directional power distribution.
We are just waiting for the release of USB4, Lower cost of Thunderbolt 3 support and otherwise the royalty-free nature of the specification means that there will be an Option Boom and we will be able to spend money on all the new devices under which the firmware is located. Until then, see this space for any news or updates!
The less pricing of Thunderbolt 3 support or else, the royalty-free nature of the specifications indicate that there will be a boom and we all are able to spend money on all the latest and newly developed devices under which the firmware is located. Till then just wait for the official release date of USB4.
