Intel Thunderbolt 4 universal cable connectivity with support for two 4K displays launched


Intel has announced its Thunderbolt 4 universal cable connectivity solution. Thunderbolt 4 will offer docks with up to four Thunderbolt ports and universal cables up to 2 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 which will work with Thunderbolt 3 PCs and accessories.
Featuring a USB Type-C port, Thunderbolt 4 cables will support double the minimum video and data requirements of Thunderbolt 3. There will be support for two 4K displays or one 8K display. Other specs include 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 port.

Thunderbolt 4 controller 8000 series is expected to arrive later this year with JHL8540 and JHL8340 host controllers for computer makers and JHL8440 device controller for accessory makers. The first PCs, laptops and accessories with Thunderbolt 4 ports will also come by the end of 2020.
“Thunderbolt provides consumers with a leading connectivity standard across a range of devices, helping to advance computing experiences and delivering on the promise of USB-C with simplicity, performance and reliability. The arrival of Thunderbolt 4 underscores how Intel is advancing the PC ecosystem toward truly universal connectivity solutions,” said Jason Ziller, Intel general manager of the Client Connectivity Division.
Thunderbolt 4 delivers 40 Gbps speeds of data, video and power over a single connection. It is compatible with USB4, DisplayPort and PCI Express (PCIe) and older generation Thunderbolt and USB products.
You can wake your computer from sleep by touching the keyboard or mouse when connected to a Thunderbolt dock. Also, Thunderbolt 4 will also provide Intel VT-d-based direct memory access (DMA) protection to prevent physical DMA attacks.
