On July 9, 2021, Intel officially announced the new thunderbolt 4 standard. Thunderbolt 4 is an iterative version of thunderbolt 3, and the transmission speed should be improved. But in fact, this is not the case. The transmission speed of thunderbolt 4 and thunderbolt 3 is the same, and the full speed is 40gb/s. thunderbolt 4 mainly increases the requirements for video transmission, data transmission and safety characteristics.
Some improvements of thunderbolt 4
1、Support wire length up to 2 meters. Longer effective transmission distance.
2、The minimum PC video specification is improved, and it supports two 4K monitors or one 8K monitor. This is a very useful upgrade for design workers who work with notebooks.
3、At least one port provides charging power up to 100W.
4、Support Wake From Sleep. After connecting the thunderbolt 4 docking station, the computer can be awakened from sleep by touching the keyboard or mouse.Provide DMA protection against attacks. Intel vt-d based direct memory access (DMA) protection to prevent physical DMA attacks.
5、In addition, the PCIe link bandwidth of thunderbolt 4 has also been improved. Thunderbolt 3 only supports 16gb/s for each PCIe link bandwidth. When connecting to external SSDs, the maximum bandwidth speed of the SSD itself cannot be achieved, while thunderbolt 4 can reach the maximum 32gb/s, twice the previous generation. Thus, the storage and transmission speed of 3000mb/s is realized, which can basically meet the external connection requirements of some medium and high-end graphics cards.
6、One cord can be extended to 3 thunderbolt 4 interfaces, which can connect more devices at a time. Weallans is the pinier of docking stations technology and solution manufacturing. By now it has lunched both both thunderbolt 3 and 4 docking station. And many agents are expanding there marketing by these new products. And MST transmission technology products are also get very good feedback from customers. With Weallans business grows ahead of your competitors.
