The Next Generation Of Usb Promises To Be Twice As Fast Using Cables You May Already Have

The actual technical specifications from the USB Application Forum, which is responsible for the standard itself, have yet to be released, but the details announced today are a bit impressive. The Promoter Group writes in a press release that USB 4 version 2 cables will use the USB-C connector, which is to be expected, but the real bombshell is this: “Key features of the updated USB4 solution include: Up to 80 Gbps operation, based on a new physical layer architecture, using existing 40 Gbps passive USB Type-C cables and recent 80 Gbps active USB Type-C cables” (emphasis theirs). Technical details for USB 4 version 2 are currently very sparse Joe Balich, a spokesman for USB-IF, confirmed that if I went out and bought a USB 4 cable right now that was rated at 40 Gbps, it could have twice that speed in the future. This is, frankly, extremely impressive. USB has always been good when it comes to backwards compatibility (and USB 4 version 2 is no exception), but being able to use the same cable and get the ultimate benefit of the new specification is another level. Balich did not explain how this was technically possible, but said that “this advantage was made a requirement when the new specification was developed, and the details of how 80 Gbps signaling is achieved will be revealed once the final specification is released.” This will apparently be done before the USB DevDays developer events scheduled for November 1st and 2nd in Seattle and November 15th and 16th in Seoul. According to the USB Promoter Group, which consists of companies including Intel, Apple, Microsoft, HP and Texas Instruments, the USB-C and power delivery specifications will be updated to “enable this higher level of data throughput” . The USB 4 version 2 specification will apparently also include updates that provide better speeds when using USB 3.2 — the promoter group promises over 20 Gbps — as well as improved support for DisplayPort and PCIe, as it will use the latest version of those standards ( the first USB 4 allows you to use only DisplayPort 1.4a when “tunneling” or transferring DisplayPort and USB signals at the same time). USB 4 v2 is very similar to a USB 5 Finally, though, we have to talk about the name. It’s a strange move to label it as just a “version 2” of USB 4 when the jump in speed certainly seems like it should be called USB 5. The standard has been confusing for a few years, though — USB 3.2 is actually a few different standards: USB 3.2 Gen 1 (also known as original USB 3.0), USB 3.2 Gen 2, USB 3.2 Gen 1×2 and USB 3.2 Gen 2×2 (which is the full 20 Gbps specification). USB 4 simplified this by having basically the same specs and capabilities as Thunderbolt 3, but now it seems we’re back to a slightly more confusing naming scheme — cable compatibility could certainly help, but I can definitely see the device spec sheets are a bit of a minefield for a while. Not that we’ll likely have to deal with that anytime soon. The press release says the update is “specifically aimed at developers right now,” while final branding and marketing guides (including things like logos) will come later. Still, it’s exciting to see what’s out there and imagine being able to transfer a 4K Blu-ray worth of data in about five seconds.
