Intel’s Thunderbolt 4.2 promises three times more power | Digital Trends Spanish


Intel has shared details about its next generation of Thunderboltwhich could be another step towards a more universal port that works with several different products.

The brand recently previewed Thunderbolt 4.2, as it’s called, detailing its specs and confirming that the port can “deliver up to three times the capacity of Thunderbolt 4,” according to the company. TheVerge.

The new Thunderbolt standard offers speeds of up to 80 gigabits per second in both directions and compatibility with existing Thunderbolt 4 cables up to one meter long, with the addition of a special mode that allows speeds of 120 Gbps up and 40 Gbps down when Multiple high-end monitors are supported on a single cable.

These specifications are very similar to the recently announced USB 4 version 2.0 standard that was introduced by the USB Promoter Group last month, The Verge noted.

However, the new Thunderbolt standard has additional features, not only USB 4 version 2.0 specifications, but also support for DisplayPort 2.1 and two times faster PCIe performance. Intel is doing its best to essentially future-proof the standard.

“Many parts of the USB4 v2 specification are optional, leading to variability in implementation, Thunderbolt sets a higher bar and offers the most comprehensive solution,” said Jason Ziller, General Manager of Intel’s Client Computing Group. , to The Verge in an email.

Similarly, the Video Electronics Standards Association (VESA) announced its latest DisplayPort 2.1 specification earlier this week, but announced its DisplayPort UHBR (Ultra-high Bit Rate) support in March as an effort to standardize video port capabilities. . With Ultra-High Bit Rate (UHBR) certification, the cables will be labeled according to their transfer speeds of “DP40” for 10 gigabits per second per lane or “DP80” for 20 gigabits per second per lane. The 40 and 80 represent the maximum bandwidth of cables using all four DisplayPort lanes. In particular, many DisplayPort dongles use USB-style ports for their connectors.

Intel plans to share more details about the official marking of its new Thunderbolt standard in 2023.
