You obviously need an AV1 hardware decoder to do hardware decoding of AV1. The GPUs you listed are the only ones with a builtin AV1 hardware decoder on the PC, though that list is also out of date. There are also multiple smartphone SoCs from Mediatek and Qualcomm that have an integrated AV1 hardware decoder. This is also not in any way an indicator for the level of hardware needed to do software decoding of AV1.
