As early as the beginning of this year’s CES 2020 conference, Intel announced a new generation of lightning 4 interface, and recently announced a detailed specification, said to have an interface to go the world, and last year, we also ushered in a new USB 4 interface, the bottom specification based on Lightning 3. So, what’s the difference between Thunder 4 and USB 4? Which is better? Intel officials conducted a detailed science poll today.
Note: Intel cannot use the name “Thunderbolt” in the country for trademark reasons, so the official name is Thunderbolt, and lightning is still used for the convenience of this article.
Thunder 4, Thunder 3 what is the difference?
Thunder3 should be no stranger to a maximum rate of 40Gbps and can support two 4K 60Hz displays for simultaneous use.
While Thunder 4 vs. Thunder 3, although the highest rate remains at 40Gbps, there are five important evolutions:
1, in the connected monitor and other scenes, the minimum PC video specifications doubled, support for two 4K display or an 8K display is the basic requirements, while the previous generation may support only one 4K display.
2, in the connection of external graphics card, hard disk and other scenes, the minimum PC data specificationrequirements doubled, PCIe minimum transmission speed from 16Gbps to 32Gbps, and when connecting storage devices, the speed of up to 3GB/s, closer to the performance when plugged directly into the motherboard.
3, the first support 4 docking station, up to 2 meters of data line, a wire can be extended out 3 lightning 4 interface, can connect more devices at once.
4, with lightning 4 PC, at least one interface can charge the device.
5, after connecting the lightning docking station, you can wake the computer from sleep by touching the keyboard or mouse.
Simply put, Thunderbolt 4 is the “more stringent version” of the Lightning 3, the lower performance limit is further improved, and extended functionality, in line with the requirements of the USB4 specification.
What is the relationship between Thunder 4 and USB4?
Both Thunder 4 and USB4 are built on the underlying protocol of Thunderbolt 3, complement each other and are compatible, with a Type-C interface with a maximum rate of 40Gbps.
However, USB4 is more versatile and less demanding, and The Thunder 4’s “lower limit” is significantly increased, it defines strict product features, validation testing, certification requirements, so the lightning-powered 4-enabled device experience is better, and of course the price will be more expensive.
In short, Thunderbolt 4 is the most comprehensive interface protocol to date, and not all USB 4s are on par with Thunder4.
Of course, they will also coexist for a long time, and because the physical interfaces are Type-C, they do not affect the notebook “one-mouthed” process.
What’s the difference between a laptop that supports Thunderbolt 4?
According to Intel’s official specifications, the computer that supports Thunderbolt 4, at least one interface to support charging, that is, the future Thunder 4 notebook, can no longer set the charging port alone, through the Lightning 4 connected monitor or docking station, can be transmitted, charge a bite to do.
Of course, there are also a lot of notebook lightning interface to support charging, but not mandatory requirements, users must carefully distinguish when shopping, the future as long as you see lightning 4 can rest assured.
In the future, you’ll never have to carry a heavy, dedicated charger with a laptop.
In addition, with the Thunder 4 notebook, when connected to the external graphics dock, you can also get better performance, because the Lightning 3 connected to the PCIe external graphics card bandwidth is limited to 16Gbps, Thunderbolt 4 doubled to 32Gbps, to meet the needs of higher-end graphics card.
The same is true when connecting an external storage device, because now that many SSDs have reached or even exceeded 3GB/s, Thunder4 can be fully released, making it no different from the straight-connected motherboard.
What is the impact of Thunder 4 on the future development of PC?
Thunder 4 fast, strong performance, the use of universal Type-C interface, can be compatible with USB4, the future of the computer only need a Type-C interface, can eliminate the previous USB Type-A, HDMI, DisplayPort, RJ-45 network port, audio port, charging port and so on, to achieve a real “one-port”, users no longer need to be disturbed by different interfaces, devices, data lines.
Type-C interface is small in size, can be inserted, can make the notebook body more simple, thin, but also let manufacturers in the product design has more room to play.
Thunderbolt 4 must support the features of interface charging, may also end the “notebook standard power adapter” era, different computers can be monitored, docking or unified charger charging, to avoid a variety of power adapters become “electronic garbage”, thereby reducing the burden on the earth.
The Intel Tiger Lake processor will debut the Power Low Power Version of The 11th Core Processor, which will be available for use with the Thunder4 interface as early as the second half of this year.
