It also added up to 100 watts of power via USB Power Delivery (USB PD), so you could use your PC to charge your phone and other USB devices-or even charge a laptop over the port. Another big change: Thunderbolt 3 no longer used the mini DisplayPort connector as its physical interface, dropping it in favor of the USB Type-C port, with the technology piggybacking on that connector, in the same way that Thunderbolt 1 and 2 piggybacked on mini DisplayPort. Thunderbolt 3 doubled the data rate-again-to 40Gbps. It combined DisplayPort and PCI Express technologies in a single cable to drive high-resolution displays and high-speed data transfers with a top speed of 10Gbps. Using the same physical port, Thunderbolt 2 doubled the bandwidth to 20Gbps and added DisplayPort 1.2 support, giving the interface the ability to drive a video signal to a 4K display. The physical form of the port was a mini DisplayPort connector with a little lightning-strike icon next to it.

Introduced by Intel and Apple, Thunderbolt first showed up on a MacBook Pro in 2011. To help you sort out how Thunderbolt 4 differs from Thunderbolt 3, as well as from USB4, we've prepared a little primer on the state of play.īefore we get into the specifics of the new Thunderbolt 4 protocol, let’s first back up and explain what Thunderbolt is and does, and how we got here. Thunderbolt 4 isn't a speed play it is more about minimum requirements than maximum speeds. These Tiger Lake-based computers are also ushering in USB4 connectivity, so there is bound to be some confusion with Thunderbolt 4 and USB4 both arriving at the same time.and sometimes, on the same actual ports.Īlso muddling up the picture is Thunderbolt 4’s lack of a single headline-grabbing feature-such as a faster top-end speed than its predecessor. Intel has kept moving Thunderbolt down the tracks and announced Thunderbolt 4 a year ago at CES 2020, and new Thunderbolt 4-equipped PCs based on Intel’s 11th Generation (“Tiger Lake”) Core processors are just now starting to roll out. This move toward open source didn’t mean, however, that Intel stopped developing its traditionally proprietary Thunderbolt specification. (And yes, the USB team dropped the space in "USB4." That's not a typo.) Indeed, the fates and directions of the two new "4" specs are intertwined. Intel opened up the Thunderbolt 3 protocol to USB's controlling consortium (the USB-IF (Opens in a new window)) for royalty-free use in the development of next-generation USB4, delivering faster speeds and interoperability to USB4 devices. The story of the latest flavor of the Thunderbolt interface-Thunderbolt 4-starts with a change in direction, however. This port looks like one of the new-style, oval USB Type-C connectors, but it does a bunch more: It can carry a video signal using the DisplayPort protocol, charge connected devices, and allow for data transfers at speeds beyond what simple USB can manage.
