Under the push of apple and Intel, lightning 3 heat rise significantly in the past two years, but what about lightning 3 interface, you might be confused. Users can see the apple MacBook, similar to the type a lightning logo near - c interface is lightning 3. Then the lightning interface can do 3, 3 of the thunder and lightning and general type - c, the following case shield to to be a science.

What interface is 3 a, thunder and lightning

Thunder and lightning in short 3 interface is the third generation of the interface of the thunder and lightning version (Thunderbolt3). Lightning is a kind of data transfer standard, the earliest is launched by Intel, combines PCIExpress data transmission technology and DisplayPort display technology, support data and video signal transmission at the same time, the main application on the physical interface mini DP. To thunder after 3 agreement, physical interface type - c because a lot of advantage acknowledged, Intel also will subsequently lightning 3 physical interface of the agreement the mini DP with type - c, with a lightning signs to distinguish, also formed the thunder and lightning we now use 3 interface.

Second, the lightning 3 interface transmission speed

Lightning 3 interface includes PCIE data transmission technology and DP display technology, the transmission speed as the name of the thunder and lightning: lightning 40 GBP 3 interfaces to support high bandwidth,

Support 8 k super clear video transmission. Lightning at the same time carry 3 physical interface for type - also known as USB - c, c support two-way power charging, support the current PD 100 w

Charging power is 20 v / 5 a.

Lightning 3 can be used as an external monitor video output interface, it can connect two 4 k @ the display of 60 hz or a 5 k @ the display of 60 hz, more visual and sound effects

三、Three, three of the thunder and lightning and general type - c

  Due to lightning 3 interfaces and type - c interface is the same, a lot of friends are confused about three interfaces of the thunder and lightning and general type - c?

The answer is lightning can be compatible with the type 3 - c. But take three interfaces of the thunder and lightning and contrast type - c interface is not too serious, because lightning 3 refers to the transfer protocol standard, and the type - c is physical protocol standard, two is not the same latitude. Because we often say the type - c refers to USB3.1 transfer protocol standard, so will the type - c defaults to USB3.1 transfer protocol standard, and lightning 3 compatible USB3.1 transfer protocol, so lightning 3 can be used on the ordinary type - c interface, and can support USB3.1 top 10 GBPS data transmission rate and the PD charge 100 w. But USB3.1 3 standard is not compatible with thunder and lightning, so general type - c equipment cannot instead of lightning 3 devices.

Summary: under the lightning 3 interface compatible type - c (USB3.1), type - 3 c is not compatible with thunder and lightning.

四、Fourth, how to distinguish the lightning 3

We talked about the above three interfaces of the thunder and lightning and the appearance of the ordinary type - c interface is the same, that is how to determine equipment lightning 3?

First look at the computer interface, appearance is c mouth, and having an interface for the thunder lightning signs 3, lightning more than three interfaces in apple MacBook and huawei MateBook X Pro lenovo ThinkPad X1 parts such as Windows high-end notebook, because of its expensive, ordinary mid-range computers don't usually carry the thunder 3 interface.

Followed by accessories device interface, lightning 3 extension equipment mainly, thunder lightning 3 cable is 3 docking station, lightning / 3 hard disk array box, such as lightning 3 equipment of high transmission rate, need on Intel lightning exclusive zhenhua three series of main control chip, its costs and prices a lot higher than the ordinary type - c. When we choose lightning 3 devices, in addition to check the computer to see if there is lightning outside 3 interface, but also pay attention to whether cable dock equipment support lightning 3, true lightning 3 equipment business is usually marked with the Intel certification and the chip, its corresponding price also in hundreds of yuan of above. Thunder and lightning and false 3 products at a low price for stunt, pretend to be the common type - c interface, but no internal lightning 3 main control chip, completely does not support the thunder 3 standards, not to mention about 40 GBPS transmission rate.

Above is lightning 3 introduces transmission speed and the effect of the interface, contains 3 methods, thunder and lightning and type - the difference between c content, such as more lightning 3 related knowledge introduction welcome to see Keith shield website.
