Intel's Thunderbolt Pushes Into Mainstream as Fast Alternative To USB (cnet.com) 193

Thunderbolt, Intel's super-speedy connection technology, isn't widely used. But that may change in the coming year, as more computer makers incorporate the USB competitor into their new models. From a report: Intel has hoped Thunderbolt, which debuted in 2011 on Apple's 2011 MacBook Pro, would become commonplace for computer users. A year later, the chipmaker forecast that "most PCs" would have Thunderbolt by 2015 to 2017. Despite the hype, only premium PCs carry the fast connection. To get a boost in adoption, Intel has built Thunderbolt into its newest Core processors, code-named Tiger Lake, which means laptop makers get Thunderbolt without having to pay extra for separate controller chips. Because Intel chips are so widely used, the company says Thunderbolt will now have its moment to shine.

"I would expect by 2022 Thunderbolt will be in more than 50% of the PCs sold," said Jason Ziller, who runs Intel's connectivity products, adding that more than half of laptops that ship in the next year will "definitely" carry the technology. Ziller has led Thunderbolt work since before it debuted in Apple's 2011 MacBook Pro laptops almost exactly 10 years ago. PC ports don't capture the imagination the way fast processors or smartphone cameras do. But they're a crucial part of most people's computing experience. Thunderbolt ports provide fast and versatile connections to external storage devices, monitors, network adapters and other peripherals. They can replace ports for HDMI, DisplayPort, Ethernet and power. The new Thunderbolt 4 lets multiport docks and hubs offer three Thunderbolt ports instead of just one.

    At least the newest version of Thunderbolt requires VT-d to provide some protection against the DMA-based attacks. That was a problem.

    • Any IOMMU will do the trick, in the mobile/embedded world we've had them for 10+ years. (for example, Tegra SMMU)
      The DMA hole was a problem with early FireWire hosts as well. And even with a simplistic IOMMU there were problems when running in a hypervisor. (Intel and AMD have resolved this for the most part)

      Intel is a little wishy-washy on what DMA protection you actually get with their TB4 sticker... The way the requirement is written allows a little wiggly room for other VT-d technologies and I'm not sure if they require it to protect everything.

      Intel's VT-d itself doesn't protect thunderbolt... it's just a means to protect DMA. Modern OS's have kernels that will use it to protect Thunderbolt connections, but doing it in the kernel still leaves known vulnerabilities. Apple initially only loaded the protection at the kernel level which led to vulnerabilities that they fixed by moving the protection into their UEFI firmware . https://www.slashgear.com/thun...

        Microsoft appears to be at the forefront of pushing these security measures earlier and earlier into the boot process. But keep in mind that your OS has to support preboot IOMMU Or you won't be able to use any of these features. In fact a lot of security features that could be used during the preboot window are often not included in the firmware because it makes life hard on the OS.

          The same dock/hub with USB instead of TB and brand new is likely half the price.
          But anyways I was talking about Thunderbolt monitors, or multi-bay SSD enclosures, external GPU. You know stuff that actually benefit from TB. They are all overpriced.

          For that reason, most people with a TB port will NEVER use any TB device. Just like most people never used Firewire.

          • The same was really true of USB 3.0 at one point. But once everyone's computer actually supported it, you finally saw faster devices to take advantage of it hit a decent price. Before that it was niche and specialty and overpriced.

            • Of course. And I expect the same will happen to USB4.

              Thunderbolt, however, will likely remain a niche. TB 1/2/3 devices never got cheap. Why would it be different for TB 4?

          • Hopefully being widely adopted will push down the price. Plugging in a single connector to get everything from fast charging to external 4k monitors to wired ethernet to real speakers is nice. At least, if it works, I have this old Dell TB16 Dock and it's remarkable how many bugs can exist in an I/O hub.
            • Hopefully being widely adopted will push down the price.

              That's the problem with "premium" connectivity. Firewire, Thunderbolt. They never get widely adopted so the price is always high.

              Plugging in a single connector to get everything from fast charging to external 4k monitors to wired ethernet to real speakers is nice.

              The problem is that USB and display port alt mode is able to do it too, for cheaper. Next generations are going to be even faster and able to drive higher resolution display. There is simply no need for Thunderbolt as well for most people.

        • I got used Thunderbolt dock with HDMI, display port, gigabit, etc. etc for $50

          Try plugging it into your phone.

          Chance are, the 50$ "Thunderbolt dock" you bought, is actually the same as most $20 docks available from no-name asian companies:
          Just a USB3+Displayport over USB-C connector.
          And it works with most modern hardware that has USB-C (though the HDMI part requires supporting Displayport alternate mode on one of the twister pairs).

          Thunderbolt is supposedly *PCIe* over a USB-C connector, not *USB3+DP*. i.e.: a different alternate mode

      I actively use Thunderbolt. I have multiple displays, plus a 10gbe NIC daisy chained from a single TB3 think on my ITX desktop.

      • So the purpose is to remove ports and force upgrades a la Apple?
      • I think that explains why it's always going to remain a niche product. Most people don't care about ITX desktops or 10 Gbps Ethernet. And those who do usually have a built-in Ethernet port, not a dongle.
        USB4 with DP mode is good enough for most uses. Even USB3 is.

          How about laptops? Plugin one cable that connects to your monitor or some sort of multidevice dock. It's worlds better than the old-school PC docks where you'd push down your laptop (e.g. Dell) and hope Windows didn't screw-up the hardware configuration.

          • Oh I see the benefit fully. It has some potential. The problem is

            1. You can do it with USB and display port alt mode too. No need for a TB controller for most people. It will only improve with USB4 and more recent DP standards.
            2. TB monitors with built-in USB, ethernet and DP ports are overpriced. I'd rather connect two cables than use that.

            However, no matter if it's a push-down dock or a USB/TB cable, Windows can still screw-up the hardware configuration, so no improvement on that.

              USB3 can only drive a single 4k monitor. I have two, so I currently have two different USB3 docks plugged into my work laptop

              • Again, good for you. But you are the niche example, not the common one. By the time dual 4k monitors setup become common, USB with DP will likely be fast enough to drive it. It might be with USB4 and DP2, whatever.

                But then you'll complain that we need TB5 to drive 4 8K monitors simultaneously. Most people couldn't care less. And because of that, TB devices will always carry a premium.

      There are not many uses for desktops; however for laptops, it becomes a single plug dock that powers the laptop and connects displays, peripherals, Ethernet, etc. Proprietary docks have existed forever and this becomes more of a universal dock.

        Work while mobile on a 10watt integrated GPU. Then plug into Thunderbolt\USB4 and attach a desktop class 200watt GPU.

    • My take is that we seem really close to a single port standard that could eliminate a bunch of other single purpose ports.

      Why would we not want a single connector that could support 10GbE, 4k displays, storage performance near NVMe and beyond SAS-4?

      Maybe TB isn't the right spec and USB4 is, but whatever, it seems like the technology/bandwidth is there except for a ton of people defending legacy good-enough connectivity.

      You can use it to connect to a dock which drives multiple displays + gigabit ethernet + power. That was the use case for me for the high end Dell I had for work a few years ago. Of course, I would have preferred it if they had kept the dock connector on the bottom as then I wouldn't have to fiddle with a cable, but one cable is the next best option to 0 I guess.

        My experience has been... less than impressive. Granted, I'm using a MBP, and most of my experience revolves around a "dock". The dock provides 2x HDMI, 1x USB 2.0, 1x USB 3.0, 1gbps ethernet, but no passthrough charging. That's fine, but the USB ports spontaneously disconnect, so I use a dedicated USB 3.0 hub. So now that's 3 cables. Bought a new monitor, but need 8k HDMI, which none of the docks supported, so I'm using a thunderbolt to DP 1.4 cable. That's 4 cables on 4 ports, to allow me to charge, get gigabit ethernet (probably going to replace the now useless dock for a 3.0 ethernet adaptor), use my keyboard, and use my ultrawide.

        As an aside, USB-C ports don't seem very robust compared to HDMI and USB type A. I was debugging some networking equipment so dragged my little dock around and I had to be careful how I positioned everything because either the doc would hang, putting it's entire weight on the plug, or try to balance it on the keyboard. Honestly, it doesn't seem much better than microusb.

    Thunderbolt 1 and 2 were both piggybacking off the mini displayport connector, which wasn't very common in anything but macs. NOW they're using the USB-C connector for thunderbolt 3, which has a MUCH higher adoption rate.

    So it comes as no surprise to me that we're going to see more thunderbolt-enabled computers.

    They need to quit biting stingy though on the number of ports on the machines. They're taking a charge port, a video port, and two USB-3 ports off and replacing it with like a pair of USB-C/TB ports, and act like that's okay. Everyone's having to buy mini-docks, not because they lack the port they need, but because they don't have ENOUGH ports. Manufacturers still trying to save a buck!
