At the CES show earlier this year, Intel announced a new generation of Thunderbolt 4 interfaces, the first of its type of Tiger Lake processor for the 10nm plus process. Intel has now officially released the Thunderbolt 4 standard at the same rate as the Thunderbolt 3 with 40Gbps, but the specifications are fully enhanced to support dual 4K output and four Thunderbolt 4 docking stations.
Although the Thunderbolt 3 to Thunderbolt 2 upgrade does not double the performance, Thunderbolt 4 still maintains a 40Gbps speed, but this speed is high enough, is the normal USB 3.0/3, 1 interface 4-8 times, 4-5GB/s speed even PCIe 4.0 mobile hard drive is enough.
The Thunderbolt 4 interface improves compatibility, reliability and security, enhances linking capabilities, is compatible with USB4, DisplayPort and PCI Express via USB-C physical interfaces, and is fully compatible with previous Thunderbolt and USB products.
Double the requirements for the minimum PC video specification and the minimum PC data specification compared to Thunderbolt 3, as follows:
Video: Supports two 4K displays or an 8K display.
Data: PCIe transmits up to 32Gb/s and storage transfer speeds of up to 3,000MB/s.
Supports docking stations with up to 4 Thunderbolt 4 ports.
The PC can be charged on at least one computer port.
When you connect to the Thunderbolt docking station, wake the computer from sleep by touching the keyboard or mouse.
Intel VT-d-based direct memory access (DMA) protection is required to prevent physical DMA attacks.
The Thunderbolt 4 will be launched in the soon-to-be-launched Tiger Lake processor, and Intel will also offer the new Thunderbolt 4 Controller 8000 series later this year, including jHL8540 and JHL8340 console controllers for computer manufacturers and JHL8440 device controllers for accessories manufacturers, including a laptop based on the Intela program in Athens.
