AMD USB4/TBT Notes

Introduction

For whatever reason it seems that AMD is not making enough buzz, compared to Intel, over their support for USB4 and Thunderbolt when it comes to their:

• Processors
• Chipsets

• Motherboards, Desktops and Laptops made by other vendors (ASUS, GIGBYTE, Framework, etc) using their chips

Let alone that the info out there might be either not clear or even confusing at times specially when it comes to whether the support is implemented via:

• Integrated controllers
• Discrete controllers

This is an effort to collect all the info I come across for later reference either for myself or others, and I hope I succeed in putting it in a way that is less confusing.
