Good comparison of TB4 vs USB 4.0
https://satechi.net/blogs/usb-4-0-vs-thunderbolt-4-0-differences-and-similarities

Some people say that USB 4.0 with full features will be compatible with TB3/TB4, even though not certified to be called TB4.

From what I read, some AMD laptops can have TB3/TB4 compatible USB 4.0 ports, even though they are not certified.
I think AMD laptop don't have TB4. TB4 is copy right product of Intel/Apple. I am not sure if Apple current product still support TB4 as they have move away from Intel chips.

Add:

Seem Apple still use TB4 technology with their M series processor.

Saw one user wrote that in other forum.

Thunderbolt4 is an Intel certification. It’s USB4 with all options enabled, Intel testing and licensing fees paid to Intel.

It’s very rare for AMD boards to have Thunderbolt, and this is not just Framework.

If you require Thunderbolt certification, get the Intel board - the 12th gen already has it and the 13th will. The AMD boards with USB4 and all options enabled will comply with Thunderbolt but won’t have the Thunderbolt certification.

For Mac users, pay attention to the the situation regarding PCIe vs USB ethernet controllers.

To be honest, with USB3.2gen2 10Gbps nowadays, 1GBps ethernet is small fraction of the bandwidth and the superfast Apple Silicon should have no issues whether the ethernet is USB or PCIe connected to the Thunderbolt.

However, if you just want to know which TB4/TB3 docks cheap out on the ethernet:
