For years, the standard Universal Serial Bus ( USB, as it is better known), is the main way to connect devices to each other through cables, especially in portable devices with computers. However, there has always been a lack of standardization between entries, but the new format, the USB4, is changing this reality, as well as making data transfer faster. 6e1b50

What are the benefits of USB4? 5h5e4x
Announced in 2019 by USB Promoter Group, the organization responsible for regulating how the standard is used, the USB4 is also compatible with the Thunderbolt, technology popularly used in Apple devices.
The main novelty of USB4, in addition to the data presented above, is doubled bandwidth — able to utilize a maximum transfer rate of 40 Gbps. If you're not familiar with the , bandwidth is equal to the number of lanes on a highway — its potential capacity — while throughput is how many cars can actually travel (or are actually traveling) at once.
A transfer tax (actual speeds) will always be equal to or less than the bandwidth (theoretical speeds) depending on all sorts of factors including the devices you are using. If you are using ports, cables and devices USB4, it can reach a maximum of 40 Gbps of transfer rate that the bandwidth allows.
That speed should be enough to transfer a movie or other large file between storages in a matter of a few seconds. In addition, the technology will also increase the efficiency of external SSDs, for example, keep your operating system somewhere outside and load it without major difficulties.
Not to mention that soon, the market will also have the standard USB4 2.0, which should arrive during the next year, this new update will allow the to transfer their data with up to 80 Gbps of speed.

During the disclosure of the new USB4 standard, the USB Promoter Group also reported that the previous generation would undergo a name change. In this way, the USB 3.0 became known as USB 3.2 Gen 1, While USB 3.1 had the official nomenclature USB 3.2 Gen 2.
The most recently USB 3.2 is technically the USB 3.2 Gen 2 × 2 – that “2×2” refers to the ability to use two high-speed channels on the same cable, for a maximum transfer rate of 20Gbps. USB 3.1 (USB 3.2 Gen 2) hits 10Gbps , while the USB 3.0 (USB 3.2 Gen 1) comes to 5 Gbps.
The format of names can seem a little confusing, because when it appeared, in 2008, the USB 3.0 it was unique on the market, but as the years ed, new updates were released to suit the advances in technology. However, the previous versions did not fall into disuse and remained on the market.
So when the USB 3.2 (now known as 3.2 Gen 2×2) arrived in 2017, there was the idea to rename the first models and also call them 3.2, so everything would be standardized. However, as not everyone adopted this change, the standards became complicated. Easily, a without much knowledge could get lost.
Thus, the arrival of USB4 technology is a great leap in the quality and speed of transferring products, after all, more than 10 years have ed between generations. See a comparison of the most powerful version of third generation with two news from the fourth:
| USB 3.2 Gen 2 × 2 | USB4 | USB4 2.0 | |
| Transfer Speed | up to 20 Gbps | up to 40 Gbps | up to 80 Gbps |
| Interface Options | USB-C only | USB-C only | USB-C only |

Now that you understand the differences between the third and fourth generation of the standard, let's move on to the second important point. Despite USB-C having a similar name, it is referring to a completely different technology.
The name USB-C refers to the cable and its connector pattern, the most modern available on the market today. Through its reversible entry, you can connect it from either side without any problems, unlike the old format, known as Micro USB. Cell phones, especially the newer ones, are the best example of this change in format.
USB4, on the other hand, represents the technological advance of the standard, with greater speed and greater quality for those who use them. Although cables and standards are developed in sets, it may occur that not all plugs USB-C have the same USB technology inside them – manufacturers can make choices about the speed and costs they are willing to pay.
To a specific USB standard, you need a device (a computer or cell phone, for example), a USB connector port and a cable that s it, otherwise the speed will be slower.

Furthermore, Intel is casting its pattern Thunderbolt 3 as part of the protocol USB4, which will bring the potential to connect monitors 4K and other devices together without the aid of a hub – something USB couldn't do.
O Thunderbolt 3 will be incorporated directly into the USB4, leading to more versatility in of data transfer rates when using multiple devices together. Although the Macs da Apple have combined the Thunderbolt 3 and USB together, to some extent, the technology is still relatively rare em Desktops and other devices.
Furthermore, there is also the Thunderbolt 4 available on the market and to have this seal of certification from Intel on a computer or peripheral, the manufacturer needs to prove to the company that its product can also all the resources and connectivity available on the USB4🇧🇷 This includes the ability to provide for the Thunderbolt 3.
However, if you're confused by these upgrades and aren't considering purchasing these new technologies any time soon, you can rest assured that the good news is that everything will be compatible with USB 2, USB 3 e Thunderbolt 3 – your existing devices will still be able to communicate with the USB4, but will occur at a slower speed. Thus, if your cable transfers files up to 20 Gbps and communicate with a newer port, it will remain with the original values and will not take advantage of new generation advancements.
In addition to speed, the Thunderbolt 4 port will also make life easier for computers because of its flexibility, as only through it will it be possible to transfer device data, video signals and even energy to compatible devices. Which offers great benefit to the USB4.
What products can be purchased with USB4? 166q64
Since it hit the market in 2021, many products have started to USB4 technology, and we will mention the main ones below. However, before buying, you need to pay attention to the specifications to see if it really s this standard.
- USB4 SSDs: are the fastest storage drives introduced, if you need speed and high performance, aligning SSDs with this technology is the best option.
- USB4 cables: in addition to providing better video quality, USB4 makes unused bandwidth accessible for power, data transfer and a host of other uses, all with just one connection.
- Apple: Currently, modern Apple desktops and laptops such as Macbook Pros, MacBooks Airs, iMacs released from 2020 onwards rely on USB4 technology. Third- and fifth-generation iPad Pros, too.
- Laptops and Processors: Some models of Intel-based motherboards and notebooks are also compatible with the standard, AMD has also released updates for its Ryzen 6000 and 7000 to it. ing that some devices do not mention the USB4, but to Thunderbolt 4.
O USB Promoter Group is made up of representatives of the Apple , HP, Intel, Microsoft, Renesas Electronics, ST Microelectronics e Texas Instruments. The group is ed by the non-profit organization USB Implementers Forum (USB-IF), which handles certification.
