Intel has outlined what to anticipate from the brand new Thunderbolt four customary, which is predicted to begin showing in client units later this 12 months.
Whereas it will not supply a rise over the 40GB/s that Thunderbolt three does, Thunderbolt four has steeper minimal necessities than Thunderbolt three for units to assert certification—and that makes some new options and perks customary.
These are the specs for Thunderbolt four, in accordance with Intel:
- Double the minimal video and knowledge necessities of Thunderbolt three
- Video: Assist for 2 4K shows or one 8K show.
- Knowledge: PCIe at 32 Gbps for storage speeds as much as three,000 MBps.
- Equipment with 4 Thunderbolt four ports
- Common 40GB/s cables as much as 2 meters in size
- Required PC charging on a minimum of one laptop port.
- Required PC wake from sleep when laptop is related to a Thunderbolt dock
- Required Intel VT-d-based direct reminiscence entry (DMA) safety
- USB4 specification compliant
Thunderbolt four will probably be suitable with all USB and Thunderbolt three connections, together with USB4—and it’ll use the USB-C cable customary. It is going to debut in laptops outfitted with Tiger Lake CPUs launching later in 2020, and Intel will supply 8000-series controller chips (Maple Ridge JHL8340 and JHL8540) for laptop makers, plus the Goshen Ridge JHL8440 controller for peripherals.
We also needs to word that Thunderbolt three and four units will share the identical, numberless branding (merely “Thunderbolt”), so telling the distinction between the 2 at a look will not be simple.
Mac customers are going to stroll away from this information with some unanswered questions, sadly. We’ve not seen something to point whether or not or how Apple Silicon Macs—that are anticipated to begin launching later this 12 months as nicely—may have Thunderbolt four ports.
The specification and rollout as described appear to preclude Thunderbolt four certification for computer systems that do not have Intel CPUs, however we will have to attend and see how this all shakes out.
