Navi 20 GPUs? All I see are Navi 21 and Navi 22

A bit confused on the AMD GPU compatibility list for AMD Hackintosh using Opencore. I see reports of 6600, 6800, 6800 XT and 6900 XT, but those come up as Navi 21. Trying to retire my current GPU.

Specs atm for a working Big Sur Opencore build is:
R5 2600
32GB Corsair Aegis 3200CL16
AMD Ref 480 8GB ASUS
AS ROCK x370 Taichi
Seagate 750W PSU
