Supported on hundreds of systems and peripherals, with dramatically higher performance, and "all of the above" protocol support, Thunderbolt 3 is now on Ultrabooks, motherboards, mobile workstations and desktops, even on a video camera.
I've been using Thunderbolt for almost 5 years and have found it to be a rock-solid interconnect from the very first, even when fully loaded with docks, storage, and monitors. It is the perfect backplane extension for mobile systems that don't even have a backplane.
Thunderbolt 3 uses the same connector as USB-C and, when supported by an Intel Thunderbolt interface chip, offers 40 Gbit/s bandwidth with half the power consumption of Thunderbolt 2. That's enough bandwidth to drive dual 4k displays at 60 Hz, PCIe 3.0, HDMI 2.0, DisplayPort 1.2, as well as 10 Gbit/s USB 3.1. Plus 100 watts of power to charge systems and up to 15W for bus-powered devices.
It's pretty cool. And the 40Gb/s version will be much more popular than v1 and v2.
Thunderbolt has faced serious headwinds since it first shipped in 2011 on Macs. The Mac's high-end market domination made them the logical choice for introducing a high-end/high-cost interconnect, but also slowed Thunderbolt acceptance on Wintel machines.
But the high-end is a small part of PC volumes, and chips need volume to get prices down. So Intel is pushing Thunderbolt 3 to Wintel vendors, who want to compete with high-spec Macs. Dozens of Wintel systems from Lenovo, Dell, HP, Asus, Acer, Razer and other vendors are available today.
But there have been other issues:
But all these issues have either been fixed or improved, which is why Thunderbolt is coming into its own.
There are a number of pro audio, video and SAN interfaces already available on Thunderbolt, and NAB-goers are prime prospects for those. What surprised me was the variety, capacity and performance of Thunderbolt storage options.
The Accusys A12T3-Share is, they say, a shareable desktop storage solution. Two 12 bay units can be linked, offering a total of 8 Thunderbolt 3 interfaces to as much as 200 TB of capacity. I'm hoping to hear more from Accusys on how they manage this feat, since Thunderbolt 3 is without a doubt the fastest and lowest cost cluster interconnect available today.
Symply integrates Quantum's StorNext cluster - the basis for the Mac's Xgrid cluster - with innovative new hardware designs to deliver up to 120TB of shareable desktop storage over Thunderbolt 3. Symply starts shipping next month.
I'm biased: I've been using Thunderbolt for years in some demanding applications and it has worked extremely well. With the move to USB-C connectors and supporting USB 3.1 (10Gb/s), as well as PCIe 3.0 and DisplayPort, Thunderbolt 3 enters the PC mainstream.
While all Thunderbolt products need Thunderbolt controllers, the ability to add Thunderbolt 3 cheaply to Wintel machines means that buyers will have the chance to future-proof their machines with a fast, robust and low-cost interconnect. That slim Ultrabook could support a powerful (and hot!) external graphics card for serious gaming or video production, while also tapping into hundreds of TB of storage.
It's taken 5 years, but Thunderbolt 3 is bringing high performance at low cost to the rest of us.
