Sandy Bridge Posted October 19, 2022 Share Posted October 19, 2022 The USB Promoter Group has announced the next version of USB, which will be backwards-compatible with USB 4.0. Rather than the names you might expect, such as USB 4.1 or USB 5.0, it will be known as USB 4 Version 2.0. You can read the official announcement at https://usb.org/sites/default/files/2022-10/USB-IF USB 80Gbps Announcement_FINAL_v2.pdf The marquee feature appears to be 80 Gbps operation, including over existing 40 Gbps passive cables. It will also be possible to configure a 120 Gbps/40 Gbps asymmetric mode. Anyone chomping at the bit to upgrade? Or perhaps to lobby the USB Promoter Group to adopt a better naming scheme? I don't think it's quite as bad as the Generation I/Generation II confusion with USB 3.1/3.2, but I'm sure there will people mistakenly buying USB 4.0 instead of USB 4.0 Version 2.0 in a few years...

Yeah, this new USB version reminded me of USB 3.1 Gen 1/USB 3.2 Gen 1 which much worse. I'm going to guess that the new version is not called 5.0 because it is backwards compatible, but I would have preferred 4.1. I'm sure we will be waiting for 1 or 2 years to see USB 4.0 2.0 devices and ports released, right? Link to comment Share on other sites More sharing options...

Yes, and thankfully this will likely fit into that quite nicely. I for one welcome this new speed-based branding. And yes, 40 Gbps is quite fast. Full speed external PCIe SSDs, it's a crazy world we live in. I think I have a 10 Gbps port as the fastest on my desktop, but it might be 20 Gbps, I'd have to find the box to look it up. I don't have an external device that's fast enough to figure it out by testing. I have no idea what my laptop maxes out at, other than it's at least 5 Gbps. If they'd introduced the speed-based labeling a decade ago, I'd know for sure how fast my ports are. 21 hours ago, IamTechknow said: I'm going to guess that the new version is not called 5.0 because it is backwards compatible, but I would have preferred 4.1. But hasn't USB always been at least mostly of backwards-compatible, as long as the connector shape is the same? Plug a USB 2.0 device into a USB 3.0 port, or vice versa, and most of the time it works just fine. I think there was some backwards-compatibility with 1.1 as well, though I'm less sure about that.
