Thunderbolt (also known as "Thunderbolt", translated as "Thunderbolt" by Apple China) is a connector standard published by Intel. It is intended to be used as a universal bus between computers and other devices. The first and second generation interfaces are integrated with Mini DisplayPort. The newer third generation has been combined with USB Type-C and can provide power.
Building on the innovation of Thunderbolt 3, Thunderbolt 4 provides a truly universal cable connection experience. Thunderbolt 4 always provides 40 Gbps speed as well as data, video and power over a single connection. It is the most comprehensive Thunderbolt specification and complies with the most extensive industry standard specifications including USB4, DisplayPort and PCI Express (PCIe), and is fully compatible with previous generations of Thunderbolt and USB products.
Thunderbolt 4 certification requirements include:
Double the mini-mum video and data requirements of Thunderbolt 3.
▪ Video: Supports two 4K displays or one 8K display.
▪ Data: 32 Gbps PCIe with storage speeds up to 3,000 MBps.
Support docking stations with up to four Thunderbolt 4 ports.
Charge your PC on at least one computer port.
Wake your computer from sleep with the touch of a keyboard or mouse when connected to a Thunderbolt dock.
Required Intel VT-d-based Direct Memory Access (DMA) protection to help prevent physical DMA attacks.
