The USB-IF introduces a simplified labeling system that shows data transfer speeds and power delivery capabilities directly on devices and cables. It replaces complex technical terms like "USB4 v2" with clear indicators like "USB 80Gbps".https://www.notebookcheck.net/USB-gets-simpler-with-new-speed-focused-labeling-system-replacing-technical-jargon.945600.0.html
USB-C >> 4 v2 >> 80 Gbps
USB-C >> 4 >> 40Gbps
USB-C >> 3.2 Gen 2x2 >> 20 Gbps
USB-C >> 3.2 Gen 2 >> 3.1 Gen 2 >> 10 Gbps
USB-C >> 3.2 Gen 1 >> 3.1 Gen 1 >> 3.0 >> 5 Gbps
USB-A >> 3.2 Gen 2 >> 3.1 Gen 2 (SuperSpeed 10) >> 10 Gbps
USB-A >> 3.2 Gen 1 >> 3.1 Gen 1 (SuperSpeed 5) >> 3.0 (SuperSpeed) >> 5 Gbps
USB-A >> 2.0 >> 480 Mbps
USB-C
80 Gbps = 4 v2
40 Gbps = 4
20 Gbps = 3.2 Gen 2x2
10 Gbps = 3.2 Gen 2 = 3.1 Gen 2
5 Gbps = 3.2 Gen 1 = 3.1 Gen 1 = 3.0
USB-A
10 Gbps = 3.2 Gen 2 = 3.1 Gen 2 (SuperSpeed 10)
5 Gbps = 3.2 Gen 1 = 3.1 Gen 1 (SuperSpeed 5) = 3.0 (SuperSpeed)
480 Mbps = 2.0
Seems like this should have been from the start or soon after various versions convoluted the technology.
Now only if other tech companies could follow suit (hint hint: Intel, AMD).
