I've been tinkering with my Vega 10 XTX (Ref AIO) for quite some time now. I have some things to share.
Here are some Superposition 4k Opt. scores to set a base line (All scores except Balanced use 1180 MHz HBM @ 950 mV and +50% PL )
Vega 64 LC "Balanced Mode" - ~6330
(P6- 1667 MHz @ 1050 mV / P7- 1712 MHz @ 1100 mV) My Vega 64 Undervolt - ~ 7100
My Vega 64 (ALL OUT) - ~ 7170-7210 (This was tested pre- Adrenalin , so I will discount this one).
That's about a 12% increase from Balanced Mode.
I've noticed that there are basically two ways of going about getting more clocks.
1) Find a desirable voltage range and find your stable clocks ( for me 1710 MHz p7 was the best I could get around 1050 mV).
2) EITHER increase voltage from that point (resulting in more Sclk) OR Increase both core and voltage to get higher p7 clocks to be stable
3) Increasing HBM eats up some core clock (for me atleast), I lost about 30-40 Mhz on the core going from 1000 to 1180 MHz
4) While you might be stable at 1800 MHz p7 @ 1000 mV, from my card and experience, the frequencies will be much lower than if you set p7 1800 Mhz @ 1.15V , that's a balancing act, what can you bear more? Better clocks? or Lower thermals/powerdraw i.e a better experience.
5) From what I remember, Turbo Mode was 2% better scores than Balanced mode for about a 70W more power draw.
Currently I'm stable and happy around My Undervolt ^ which gives me about 1680 MHz in-game like Assassin's Creed Origins and takes up about 210W ( That would be 260-270W in other titles). For some reason either AC:O is SCARY efficient or Vega runs this game way too efficiently.
A TLDR Conclusion I've come to personally like many other users - Going from my undervolt to my 'ALL OUT' mode will barely give me 1 fps (if not less) while consuming about 70-90W more (Because I'd need to push Voltage from 1.08-1.1V to 1.2V to go from 1710 to 1752 MHz @ p7).
I will update as I find more things.
