Not sure whose fault it is but the ports on the AMD-based framework laptops are a mess. The framework 16 has four different specs across its six USB-C port and the framework 13 has three different specs across four ports. Meanwhile their intel-based laptops have four identical ports with USB4, USB-PD and Display Port.
I must be living under a rock because this is the first I've heard of USB 4. Is it just a speed bump or does it affect the type of data that can be transferred? In my experience I've had issues using a usb 2.0 flash drive to use a live image of a Linux iso in a 3.1 port
It bumps the speed and officially supports Displayport and PCIe protocols being tunneled through.
Also, as a tiny nit for seemingly no other reason than to piss us all off, they have decided the "correct" way to write it is "USB4" (no space). This is in contrast to every previous version of USB such as "USB 3" (space).
I would have been better off not knowing about the spaces
It's basically ThunderBolt 3 without the licensing.
