wait when the h*ck did we get usb 4
Bruh, when we got PC^2^ gotta pay attention lol
In serious tho, it's been out for a few years, but I don't think it gets used much outside of high-performance stuff like this
Laptops have it where they used to have thunderbolt 3. usb4 is basically just standardizing and opening tb3.
You might notice linux using a usb4 module to support older tp3 ports for that reason.
Desktops still barely even have usbC, so thunderbolt or usb4 never really got to them.
I think about 5 years ago. My motherboard has it
