Shouldn't "need to" be replaced by "should" ? Or if it was really "need", how come everything has been working fine without those golden registers ? Anyone from AMD would dare to comment on that ? Thanks!
According to this Git commit, golden arrays for AMD Radeon graphics processors come down to arrays of register settings that need to be initialized at the ASIC (GPU) start-up.
The sets of new "golden" registers to initialize at start time were added for the Radeon HD 4000 (R7xx), Radeon HD 5000 (Evergreen), Radeon HD 6000 (Cayman / Northern Islands), and the Radeon HD 7000 (Southern Islands) series.
