New Thunderbolt version will be up to 4x faster: 120 instead of 40 Gbit/s

New Thunderbolt version will be up to 4x faster: 120 instead of 40 Gbit/s

[14:30 Fri,21.October 2022   by ]    

Intel has introduced the new USB 4 version 2.0 as well as the next generation of Thunderbolt, which will at least show a big improvement. Intel has not yet decided what the new Thunderbolt will be called, but it is clear that the version provisionally called "Nex Gen" will have many of the capabilities that are only optional for USB 4 V2 as standard.

So - as before - Thunderbolt will guarantee a very well defined set of capabilities including a very high maximum speed amidst the whole confusion of possible speeds and features of the different USB versions (what&s the difference between USB Gen 3.2 and USB Gen 3.2 2x2?).

The most important innovation is probably the speed - after the speed increase failed during the last version jump from Thunderbolt 3 to version 4 (both were 40 Gbit/s fast), this is now made up for: the new Thunderbolt can now support 80 Gbit/s (10 GB/s) via four channels bi-directionally (i.e. via 2 channels at a time). In an asymmetrical new mode, in which more data is transferred in one direction than in the other via 3 channels, it can even transfer 120 Gbit/s (only 40 Gbit/s in the other direction via one channel at the same time). This particularly fast one-way mode has been specially developed for transfers to 8K monitors, for example, which do not require a fast return connection (i.e. data transfer from the monitor to the computer), but also archive/backup systems connected via Thunderbolt or external GPUs will benefit from the increased speed. The new USB 4 2.0 can optionally transfer at 120 Gbit/s - but only 20 Gbit/s are guaranteed.

The new Thunderbolt version - which continues to rely on USB-C ports - is supposed to automatically detect when the increased bandwidth is needed. PCIe bandwidth has also been increased (and doubled). As always, the new Thunderbolt version is supposed to be backwards compatible with older Thunderbolt, but also USB and DisplayPort versions. The new DisplayPort 2.1 standard is also supported, which enables connections to two 120 Hz 8K monitors.
