I get the sense, just from anacdotes on the web, that power delivery systems with higher-current power phases (but fewer in number) seem more prone to coil whine.
I have a TUF 6800XT that I have used in three rigs with 3 different PSU's. Certain configurations were quiet and others had coil whine.
EVGA GA 750 + Gigabyte X570 MB = coil whine
Switched the power supply in that rig to a Superflower 850 and it was silent.
Sold that rig with my old 3080 in it and used the 6800XT temporarily in an X299 Intel build with the same GA 750 from before and the whine returned.
Decided it was too anoying even with the limited use of that rig, and installed a Corsair RM850 PSU expecting it to get rid of the whine the way the Superflower PSU did. Well, not exactly.
It was quieter, but still there. I thought the Superflower PSU was just better...until I built another X570 rig with a Uinfy board pulling both the Corsair and 6800XT for use in that rig.
With this most recent combo, the coil whine is gone.
So while the 6800XT clearly has "special needs" to avoid coil whine, success is dependent on the PSU *and* motherboard used.
