HIGH-speed connection protocol Thunderbolt is getting an
update to a new standard, with Intel announcing the arrival of Thunderbolt 4
The current Thunderbolt 3 standard uses USB-C connections,
which is set to continue with the new standard.
According to the official announcement from Intel,
Thunderbolt 4 will deliver speeds of 40GB/s as well as being able to support
docks with up to four Thunderbolt ports and universal cables up to 2m long. Intel
have also confirmed the new interface will be fully backwards compatibly with
Thunderbolt 3 and USB-C accessories, cables and the like too.
The upcoming Intel Tiger Lake laptop processors, due later

Required Intel VT-d-based direct memory access
(DMA) protection that helps prevent physical DMA attacks.”
Intel client connectivity division general manager Jason
Ziller said Thunderbolt provided 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,” he
