These scores are on xfx black stock core (1328) and 2050mhz ram speeds with newest drivers. I undervolted every state in wattman by 25 - 793 stage 1, 806 stage 2, 931 stage 3, 993 stage 4, 1037 stage 5, 1085 stage 6, and 1125 stage 7. I also upped the power limit to 10% and the fan limits to 2500/3600 which honestly weren't that bad. Temps never exceeded 69c.
I boosted it up to 1350, but no real change. If I go any higher the drivers crash as soon as the gpu goes under load.
I'll set up a spreadsheet tomorrow or some time this weekend showing the differences between power levels/voltages/temps etc.
I'm averaging a gpu score of 13700 which would put me between a fury, and a furyX.
As The Mac said, it is pretty good. A 290 at 1200 gets about 13600 but not many can game at those speeds. If this 480 can maintain it for games, then it is really a good upgrade path for those who are still using Tahitis or Tongas.
The AIBs should be able to clock higher. At 1500 core it may way outperform even the 390X. Then comes DX12.
