It's funny how everything is optional on the usb 4 features graph.
Can you do 5 W and 1.1 Mbps and call it usb 4?
Can you do 5 W and 1.1 Mbps and call it usb 4?
USB4 40 Gbps: Referred to as USB4 Gen 3x2
USB4 80 Gbps: Known as USB4 Gen 4
USB4 Version 2.0 120Gbps
I guess if you're required to support 120Gbps on even cheap small electronics then USB 4 support doesn't make sense
And btw the list above includes only the data speed, not the charging capacity.
