Yes, it is called the Equivalence Table and can be found encoded at the top of the AMD microcode containers that Linux distros usually include. I’m only aware of these relations, but maybe there are more:

{
    "100F20": [
        "100F20",
        "100F2A"
    ],
    "100F41": [
        "100F41",
        "100F52"
    ],
    "100F43": [
        "100F43",
        "100F53"
    ],
    "100F81": [
        "100F81",
        "100F91"
    ]
}

127 is completely left out of the Intel instability story (125 → 129 → 12B).

Probably some test version for OEMs to validate before the “proper” (? ) fixes of 129 and 12B.
