Next-gen Thunderbolt details: 40Gbps, PCIe 3.0, HDMI 2.0, and 100W power delivery for single-cable PCs

For the last few years, Intel and Apple have worked to create an ecosystem around Intel’s Thunderbolt interface, formerly known as Light Peak. The first generation Thunderbolt interface offered four independent lanes at 10Gbps down a single cable, while Thunderbolt 2 allowed those lanes to be combined into two 20Gbps channels. It looks like Thunderbolt 3 (codenamed Alpine Ridge) further doubles up on performance by increasing bandwidth to 40Gbps (around 5.1GB/sec). That’s enough bandwidth for multiple 4K video streams off a single controller or ultra-fast high-end PCI-Express SSDs — or at least, it will be if Intel fixes the backhaul problem.

Check the listed features and you’ll note that the new standard is PCIe 3.0 compatible. That probably means that it supports the PCI Express 3.0 standard for remote graphics cards, but frankly we’ll be more excited if it also supports PCIe 3.0 for the actual motherboard link. Both Thunderbolt and Thunderbolt 2 relied on a single PCIe 2.0 x4 connection, with a peak maximum bandwidth of 1.6GB/s. While that’s sufficient for most modern hard drives, hanging a secondary GPU off a PCIe 2.0 connection and then attempting to drive a high-end monitor off it isn’t going to fly at 4K.

PCI Express 3.0 support for graphics card enclosures is a nice marketing bullet point, but PCIe 3.0 support for an x4 linkage between the TB controller and the motherboard would actually matter as far as high-end graphics performance.

The other two major features of the new Alpine Ridge controller are its support for HDMI 2.0 (allowing for 4K resolutions at 60Hz) and the implementation of a 100W power delivery capability (just like the USB Power Delivery spec). This will allow companies like Apple to build single-cable MacBook products — there won’t be any need for a separate power connector for charging the device. Other PC manufacturers could also follow suit, though high-end laptops with more than 100W of power consumption will continue to rely on separate bricks. Intel is also promising sharply reduced power consumption and two different controller SKUs, presumably to give manufacturers a lower-cost option.
