USB 4 version 2 promises 80 Gbps speeds over existing cables
> The press release says that the update is “specifically targeted to developers at this time,” with final branding and marketing guides (including things like logos) to come later.<p>I choose to believe that there is still time to fix all this.<p>Here is what they need to do:<p>* Specify a set of power tiers: 15W, 30W, 100W.<p>* Specify a set of bandwidth tiers: 10Gbps, 20Gbps, 40Gbps, 80Gbps<p>* Specify a set of icons representing protocol capabilities (e.g. “DP” for DisplayPort)<p>* Mandate that every port and cable is labelled with those two numbers and any associated icons.<p>* Call it USB 5.<p>* Drop all the “2x2” and “version 2” and “Gen2” and “SuperSpeed+” terminology.<p>Apologies if I forgot some dimension of USB functionality.
