The next version of USB<\/a> could be one of the fastest connectors we\u2019ve seen yet. The USB Promoter Group says that USB 4 version 2.0 will be capable of speeds up to 80 Gbps, double what the original USB 4<\/a>, and even Thunderbolt 4<\/a>, are capable of. <\/p>\n
The actual technical specification from the USB Implementers Forum, which is in charge of the standard itself, hasn\u2019t been released yet, but the details coming out today are a little stunning. The Promoter Group writes in a press release that USB 4 version 2.0 cables will use the USB-C connector, which is to be expected, but the real bombshell is this line: \u201cKey characteristics of the updated USB4 solution include: Up to 80 Gbps operation, based on a new physical layer architecture, using existing<\/em> 40 Gbps USB Type-C passive cables and newly-defined 80 Gbps USB Type-C active cables\u201d (emphasis theirs).<\/p>\n
\nTechnical details on USB 4 version 2.0 are currently very sparse<\/q><\/aside>\n<\/div>\nJoe Balich, a spokesperson for the USB-IF, confirmed that if I were to go out and buy a USB 4 cable right now<\/a> that was rated for 40 Gbps, it would be able to do twice those speeds in the future. That is, frankly, extremely impressive. USB has always been good about backward compatibility (and USB 4 version 2 is no exception), but being able to use the same cable and still reap the flagship benefit of the new spec is another level.<\/p>\n
Balich didn\u2019t explain how that was technically possible but said that \u201cthis benefit was made a requirement when the new specification was developed and the specifics as to how 80Gbps signaling is accomplished will be disclosed once the final specification is released.\u201d That\u2019ll apparently be before the USB DevDays developer events scheduled to happen on November 1st and 2nd in Seattle and November 15th and 16th in Seoul.<\/p>\n
According to the USB Promoter Group, which is made up of companies like Intel, Apple, Microsoft, HP, and Texas Instruments, the USB-C and power delivery specs will be updated to \u201cenable this higher level of data performance.\u201d The USB 4 version 2.0 specification will also apparently include updates that provide better speeds when you\u2019re using USB 3.2 \u2014 the promotors group promises over<\/em> 20 Gbps \u2014 as well as improved support for DisplayPort and PCIe since it\u2019ll be using the latest version of those standards (the first USB 4 only let you use DisplayPort 1.4a when \u201ctunneling,\u201d or carrying DisplayPort and USB signals at the same time).<\/p>\n
\nUSB 4 v2 feels a lot like a USB 5<\/q><\/aside>\n<\/div>\nFinally, though, we have to talk about the name. It\u2019s a strange move to label this as just a \u201cversion 2.0\u201d of USB 4 when the leap in speed definitely feels like it\u2019d warrant being called USB 5. The standard has been confusing for a few years now, though \u2014 USB 3.2 is actually a few different standards<\/a>: USB 3.2 Gen 1 (AKA original USB 3.0), USB 3.2 Gen 2, USB 3.2 Gen 1\u00d72, and USB 3.2 Gen 2\u00d72 (which is the full-fat 20 Gbps spec). USB 4 kind of simplified this since it basically had the same specs and capabilities as Thunderbolt 3, but now it seems that we\u2019re going back to a slightly more confusing naming scheme \u2014 the cable compatibility could certainly help, but I can certainly see device spec sheets being a bit of a minefield for a while.<\/p>\n
Not that we\u2019ll likely have to deal with that anytime soon. The press release says that the update is \u201cspecifically targeted to developers at this time,\u201d with final branding and marketing guides (including things like logos) to come later. Still, it\u2019s exciting to see what\u2019s in the pipeline and to imagine being able to transfer a 4K Blu-ray\u2019s worth of data in around five seconds. <\/p>\n<\/div>\n
