Thunderbolt 4 is based on the USB 4 standard, and Thunderbolt 5 is based on the USB 4 v2 standard. The difference is that the USB standards allow lots of features to be optional, while Thunderbolt makes some of the features mandatory. In real life, this means that a USB 4/5 device will always...

Anything that needs 20-40 Gbps speeds would be able to saturate USB4. Say, a USB4 NVMe enclosure with a Gen4/Gen5 SSD. And of course, video as in just your DisplayPort 2.0+ signal: 8K/60Hz/10-bit uncompressed is 80 Gbps (works because 40 Gbps is bidirectional bandwidth).

This. You only see USB4 (and TB3, before that) on premium boards that have to use a separate chip - generally ASMedia for USB4 - which in turn connects to the CPU/SB via PCIe. I expect we'll see native USB4 on the Zen6 IOD, and perhaps on the higher-end Zen5 chipsets.
