Chipzilla has revealed more about Thunderbolt 4 - its cable connectivity product - and is telling anyone who will listen that it can docks with up to four Thunderbolt ports and universal cables up to two meters in length.

Intel’s upcoming mobile PC processors, code-named “Tiger Lake,” will be the first to integrate Thunderbolt 4. Intel also announced the Thunderbolt 4 controller 8000 series, compatible with the hundreds of millions of Thunderbolt 3 PCs and accessories already available. Thunderbolt 4 developer kits and certification testing are now available.

Thunderbolt 4 builds on  Thunderbolt 3 and always delivers 40 Gbps speeds and data, video and power over a single connection. It is the most comprehensive Thunderbolt specification yet, Intel claims, with compliance across the broadest set of industry-standard specifications – including USB4, DisplayPort and PCI Express (PCIe) – and is fully compatible with prior generations of Thunderbolt and USB products. Thunderbolt 4 certification requirements include:

Double the minimum video and data requirements of Thunderbolt 3.
Video: Support for two 4K displays or one 8K display.
Data: PCIe at 32 Gbps for storage speeds up to 3,000 MBps.
Support for docks with up to four Thunderbolt 4 ports.
PC charging on at least one computer port2.
Wake your computer from sleep by touching the keyboard or mouse when connected to a Thunderbolt dock.
Required Intel VT-d-based direct memory access (DMA) protection that helps prevent physical DMA attacks. (Read more in the

The arrival of Thunderbolt 4 underscores how Intel is advancing the PC ecosystem toward truly universal connectivity solutions.”

Kensington vice president and general manager Ben Thacker said: “We expect Thunderbolt 4 products to be an inflection point for accessory makers who depend on PCs and Macs to offer an industry-leading set of product capabilities for a consistent user experience. The advancements in Thunderbolt 4 will help Kensington redefine the modern workspace of the future."

Lenovo plans to expand its support of Thunderbolt with the introduction of Thunderbolt 4 PCs and the expanding portfolio of Thunderbolt accessories
