Intel has been working on it for a while Thunderbolt 5, a version that gives a new twist to Thunderbolt 3 from a few years ago, because Thunderbolt 4 was more of a slight improvement to iron out rough edges in the standard. After showing it in operation last year, it has now officially announced it, which opens the doors to improvements on all fronts of communication with peripherals.
From the outset, communication is now 80 Gb/s instead of 40 Gb/s, twice as much, which opens the doors, for example, to a PCIe 4.0 ×4 communication interface for external solid state drives (SSD) of this type. . But it could also be configured as una PCIe 3.0 ×8 (about PCIe 4.0 ×4) to be able to use external graphics cards without problems, because the current Thunderbolt 4 only allows PCIe 3.0 ×4, which limits almost any eGPU above an RTX 4060.
Those 80 Gb/s are bidirectional, two 40 Gb/s channels in one direction and two 40 Gb/s channels in the other. Can be configured to three and one for 120 Gb/s bandwidth in one direction and 40 Gb/s in the other. For example, it will be useful for high resolution, high refresh rate external monitors. In theory you could configure a PCIe 3.0 ×15 or PCIe 4.0 ×7 connection in one direction for an eGPU, but the eGPU connection will be configured by Intel, NVIDIA and AMD drivers and is obviously not a particularly round number.
As for Thunderbolt 5 supported alternate modes, you can use the one from 240W power deliverythat of DisplayPort 2.1and compatibility with USB 3 and USB 4, the latter based on Thunderbolt 3 courtesy of Intel.
The first PCs and accessories with Thunderbolt 5 will arrive sometime in 2024.
