Intel has officially abandoned Windows 7 support for your latest processors and actually sounds like AMD is taking identical route as AMD Raven Ridge doesn't support Windows 7.

Consistent with Reddit user, roflmaono, AMD Raven Ridge doesn't support Windows 7 probably "due to ACPI issues while in the BIOS".

Furthermore, this problem can't be bypassed upon an external GPU. As reported by the Redditor, this can't be resolved until BIOS update in the required ACPI permissions for Windows 7 is introduced.

This rrs not going to change until incase BIOS updates supporting the ACPI permissions for Win7 are meant. I have tested this with ASRock and Gigabyte ITX motherboards. Concerning spoken briefly with ASRock support and so they blame AMD despite it to become BIOS issue.
