I am trying to decide on a new Catalina compatible graphics card and found this post. The device models shown below in orange are from the Device Hunt website (https://devicehunt.com) where they have "a massive database of USB and PCI devices." If you're looking for some of the other/older devices in the list above where the model info is shown as unknown, you may have luck there. onemanosx used the same source for some/all of the device/vendor-ID-to-model-name mappings in the original list, and I'm guessing that at least some of the Navi 14 and Navi 12 mappings weren't there at the time the original post was put together.
I'm currently using 10.15.7 (19H2) so I thought I'd look into the graphics kexts there to see whether the list had expanded since 10.15.2 (19C57). I thought I knew where to find them, but it's been a while since I looked into this, and I didn't find them. If someone could tell me in which kext I could find the device/vendor IDs listed, I would appreciate it.
Thanks.
