The take-away is that nVidia only has hardware support for AV1 on the RTX 3000 Ampere series cards.
Intel supported AV-1 decoding in its Xe-LP GPUs in 2020.
Intel also reached v1.0.0 of its open-source codec 2 weeks ago, here: https://github.com/AOMediaCodec/SVT-AV1
I am not aware of any other CPU or GPU that has an AV-1 codec built in.
