Intel today an**unced that it plans to drive large-scale mainstream Adoption of Thunderbolt by releasing the protocol's specification to the industry next year under a **nexclusive, royalty-free license.
The move should help expand the Thunderbolt ecosystem by making the protocol more affordable for tech**logy companies and accessory makers alike. Intel expects third-party Thunderbolt-compatible chip development to accelerate a wide range of new devices and user experiences.
Intel also revealed plans to integrate Thunderbolt 3 Into its Future CPUs, but it didn't provide a timeline as to when. The all-in-one design will take up less space on a Mac or PC's logic board, and reduce power consumption by eliminating the need for a standalone Thunderbolt controller.
?Apple and Intel have collaborated on Thunderbolt from the beginning, and as the industry leader in its adoption, we applaud Intel?s efforts to integrate Thunderbolt tech**logy Into its CPUs and open it up to the rest of the industry,? said Dan Riccio, Apple?s senior vice president of Hardware Engineering.
Intel said Thunderbolt 3 built Into the processor could pave the way for thinner and lighter devices, although the current Thunderbolt 3 controller used in Apple's latest MacBook Pro has a package size of 10.7mm×10.7mm, so any logic board space saved would likely be negligible.
The greater benefit will likely come from Thunderbolt 3's increased power efficiency, paving the way for longer battery life.
Thunderbolt 3 carries power, USB, DisplayPort, HDMI, and VGA over a single port that shares the USB-C connector design, creating one standard for connecting most accessories and peripherals. Apple's latest MacBook Pro has two or four Thunderbolt 3 ports depending on the model.
Thunderbolt 3 can transfer data at speeds up to 40Gbps, allowing for a full 4K movie to be transferred in less than 30 seconds. The interface is suitable for 4K virtual reality experiences on PCs, high-end gaming, and single-cable peripherals such as external displays, docks, and storage drives.
