USB4 brings better speeds and compatibility – but loses its place in the name – TechCrunch



Organizations behind the widely adopted USB standard have released some new information on the latest iteration of the interface, and this is only good news for consumers. It's faster and offers better compatibility without having to worry about which cable or connector to use. And pedants notice: After "USB" and the number is no longer a space.

USB4, as it is now designed (compared to USB 4), was announced in March with some promises in terms of features, but now with the actual technical specifications released for anyone who wants to inspect them. It is another step on the way to turning an important standard from idea to reality.

There are three major improvements in USB4 over USB 3 (or 3.2 or 3.1

gen2v2 … the naming system is a mess):

[19459005BetterSpeed​​ USB4 achieves peak performance of 40 gigabits per second, twice as fast as the latest version of USB 3 and eight times as fast as the original USB 3 standard, which of course itself was much faster than what it replaced. It also supports the maximum speed of previous cables and interfaces.

Compatibility with Universal Thunderbolt 3. Thunderbolt 3 is the proprietary implementation of Intel's USB 3, which can be found on Intel boards and on all companies that have licensed the technology , However, Intel has realized that it was counterproductive to split off such things. Therefore, they provide the Thunderbolt 3 specification for free. Anyone making a USB4 device or cable can make it compatible with the Intel standard. It is possible, but unlikely, that some people choose not to. There is no reason for that, but who knows?

Improved display / data distribution. USB 3 introduced the ability to send stream, data and a video signal (basically just more, but special data) over a single cable over a single cable. Great! But sometimes, depending on how you set it up, it could only send one or the other, or the speed was greatly reduced. USB4 does that much better. So if you have a monitor that uses 8 Gbps for video bandwidth, the full 32 Gbps will be available for other purposes. It's just one of those behind the scenes changes that make things better and easier for everyone.

The other good news about USB4 is that it does not use a new port. We are still in the transition phase from the large rectangular connector, the small trapezoidal connector, the large trapezoidal connector, etc. to the stylish USB-C connectors, which you can not go wrong even if you try. A renewed change would be catastrophic – the connection is the same.

Two not so good news: It will not be here for a while and it could be a little more expensive. These ports are complicated and the ability to send more data, power, etc. means that it's a bit harder to create. And although the specification will be released today, it will almost certainly take at least a year for products to come onto the market that use them.

That's the name. The computer hardware industry is known to be bad at naming things, and USB 3 was no exception to that rule. It was always annoying to find out which USB version is supported, what that means and so on. From now on, USB4 is the name until USB5 comes out.

Brad Saunders, CEO of the USB Promoter Group, told Tom & # 39; s hardware that they just wanted to simplify things and prevent the proliferation of versioned products that could confuse consumers.

"We do not plan to go in an iterative way of Art 4.0, 4.1, 4.2," he explained. "We want to keep it as simple as possible. When and when it gets faster, we just have the faster version of the certification and the brand. "
