The very cheap stuff, even expensive Chinese Phones, still use the outdated USB 2.0 protocol. New GPU must be supported by AMD XConnect™ technology. Other minimum requirements include that Thunderbolt 4 docks must wake the PC from sleep and that notebooks requiring less than 100W of power must include at least one Thunderbolt 4 port for charging. need to meet a minimum set of requirements, Protection from direct memory access (DMA) attacks, will continue to support Thunderbolt technology, https://www.theverge.com/circuitbreaker/2020/7/8/21317980/apple-silicon-intel-thunderbolt-arm-macs-support-usb-c, Google’s Fuchsia OS is an open source project that now accepts community code contributions.

So what we can expect is USB4 is going to be worse than TB3 in the real world. GIGABYTE B550 VISION D AM4 AMD B550 ATX Motherboard with Dual M.2, SATA 6Gb/s, USB 3.2 Type-C with Thunderbolt 3, WIFI 6, Dual Intel GbE LAN, PCIe 4.0 Number of Memory Slots: 4×288pin Thunderbolt 4 laptops with Xe dGPU-level graphics teased with Intel Tiger Lake 10+ nm hardware By Andrei Girbea - @ andreigirbea , last updated on November 25, 2020 Coming out of CES 2020, this year looks like it’s AMD’s time to shine. Kensington has released its first Thunderbolt 4 docking station, and it is a lot better than the OWC Thunderbolt Hub. Thunderbolt 3 is usually found on an Intel-based PC, but not exclusively. AMD xConnect in Windows 10 does work with Thunderbolt 2.0 but there are some limitations on PC as I think it has been implemented with laptop use in mind. TB4 tries to make a few improvements over TB3, and I believe, vendors will stick with USB 4 for the most part. I’m waiting to see some research and maybe a white paper about Wireless interference from the USB4/TB4 data transmissions. The same goes for USB4 cables and docking accessories. Both are capable of data transfer speeds up to 40GB/s. ), “We do not find much demand from OEMs for Thunderbolt support,” an AMD representative said in an email when asked by PCWorld, before Intel’s announcement, why there had been few, if any, Ryzen-based notebooks with Thunderbolt in them to date. On Apple Silicon? We now know it will support 40Gbps throughput, but with tighter minimum specs. AMD’s position has been that its customers don’t want Thunderbolt. Obviously Intel is playing up the benefits of Thunderbolt 4 not being an open standard. Apple likes Thunderbolt. But theoretically there’s nothing stopping USB4 device and accessory makers from incorporating most of the same technologies. However, the minimum requirements are actually lower, and the certification to get USB 4 is actually more lenient than TB3. It has nothing to do with your comment because I didn’t reply to you.

But it appears that the new I/O spec isn’t as fresh as its title would imply. Intel teased the Thunderbolt 4 interface earlier this year at CES 2020 with little detail, though a bit of digging revealed that the new interface isn't faster than the existing Thunderbolt 3. And Intel says the minimum video and data transfer speed requirements for Thunderbolt 4 are double those for Thunderbolt 3. Beyond that, Thunderbolt 4 will require Intel VT-d DMA protection and support for accessories like docks that have four Thunderbolt ports. Save my name, email, and website in this browser for the next time I comment. Running nuclear, Previous yr, Kit Willow designed two important modifications: She relocated all her manufacturing back residence to Australia, and she moved. Thunderbolt is an Apple developed technology. Intel unveiled Thunderbolt 4 on Wednesday, tightening the existing I/O specification for docks, some displays, external storage and GPUs. “There’s no technical reason preventing AMD from supporting Thunderbolt. Still, there’s no guarantee that a USB4 product will support top speeds exceeding 20Gb/s or that it will support multiple high-resolution displays or USB power delivery capable of charging a laptop. Intel may be the driving force behind the technology at this point, but it was initially developed in partnership with Apple. Compared to Thunderbolt 2, it doubles the bandwidth to 40 Gbit/s (5 GB/s), allowing up to 4-lane PCIe 3.0 and 8-lane DisplayPort 1.2. To be clear, DMA is direct memory access, not attack, but what they are trying to prevent are direct memory access attacks (DMA attacks). Intel’s still pitching Thunderbolt as a single standard to rule them all, but the reality up to now has been complicated. Oh, there’s one more interesting thing to note about Thunderbolt 4. Because VT-d based direct memory access (DMA) is strictly an Intel technology, however, this requirement seemingly creates a barrier for AMD. According to Ziller, hundreds of millions of PCs and PC accessories have shipped with Thunderbolt 3 silicon inside. Peripherals will evolve, too. Triple M.2 slots. Thunderbolt 4 will debut later this year as part of Intel’s “Tiger Lake” CPU platform, as Intel originally announced during CES in January. Overlooked No Additional: Brad Lomax, a Bridge Amongst Civil Rights Actions. Just as “next” said, the comment format/display and general reply issues has been happening for the last while due to the ongoing changes to this site. Thunderbolt docks are rising, too: Intel projects 20-percent growth, versus the 10-percent annual growth of cheaper, slower USB-C hubs. “If [at AMD] there was an equivalent technology that supports DMA protection, that supports prevention against physical attacks, then that would be the requirement.” Ziller deferred to AMD as to what that technology could be, and he also declined to say whether Intel would license the VT-d technology to competitors. I’ll see if I can do something about that. Up until now, glancing at a USB-C port wasn’t necessarily enough to tell you if you were looking at a USB 2.0 or USB 3.x device. Well, that was easier than I thought — just had to flip things so that the most recent comments are on top rather than the bottom, which probably makes more sense anyway. Displays have been slower to pick up the technology. But there are also some key differences. TB3 also allowed for the use of … Thunderbolt is a brand name for technology developed by Intel and Apple. Intel says the key feature for these new Thunderbolt 4 docks will be four Thunderbolt ports for connecting multiple devices, in either a tree structure, or by daisy-chaining them. We’re already seeing compact docks like Belkin’s Thunderbolt Dock Core, including some that are strictly bus-powered, in addition to larger, bulkier, more full-featured docksRemove non-product link manufactured by Lenovo and others. Project Athena collaboration with PC vendors to develop premium thin-and-light notebooks. Looks like Apple answered your question: https://www.theverge.com/circuitbreaker/2020/7/8/21317980/apple-silicon-intel-thunderbolt-arm-macs-support-usb-c, “Over a decade ago, Apple partnered with Intel to design and develop Thunderbolt, and today our customers enjoy the speed and flexibility it brings to every Mac.
