<p>With a PC equipped with Thunderbolt 4, it becomes possible to connect two 4K displays, which was one for Thunderbolt 3, and it also supports 8K output. The PCIe data transfer rate has also been increased to 32Gbps, which is twice the speed of Thunderbolt 3, and the data transfer to storage is also improved to 3000Mbps.</p>

Thunderbolt 4 will be compatible with USB 4 and will provide higher level functionality. In terms of security, use DMA in PCIe transferThunderspyIntel Directed I/O (VT-d) is a mandatory specification to prevent attacks.

So what about PCs equipped with AMD or Arm CPUs other than Intel CPUs, Intel says that these CPUs can also be used because they have a memory management unit (IOMMU) to use DMA. .. However, it is necessary for the OS to support this.

Intel will implement the CPU (Tiger Lake) Thunderbolt 4 that will appear in 2020, and will also ship a Thunderbolt 4 controller to manufacturers. In addition, a PC that is compliant with the modern PC specifications "Project Athena" promoted by Intel will be announced later this year.
