Am i? Who cares what the card power limit is design for, what matters is the real power consumption no?
Can you try run 580 vs 480 at similar clock speed and voltage?
In the end RX-580(Polaris 20) is the same RX-480(Polaris 10) but with improved manufacturing process so it could reach higher clock speed.
Yes it really improved on clock speed but at the cost of power draw. Can you try run 580 vs 480 at similar clock speed and voltage?

I already have RX 580 and have been using it for a week, I confirm the power draw is higher than the RX 480 (reference) that I used.
I look at my benchmarks, it is as what AMD mentioned - maximum 12% gain. That's just maximum, average is 5% - 10% gain which is very little for that added power draw.
Put it simple, RX 580 (only custom available) at around 180W power draw vs RX 480 (reference) that performs almost like the RX 580 but at less than 150W.
BUT realistically speaking, in the end not many people really care about power draw. Add 30W only even though on % looks big.
So if you look at what you gained vs what you lose, the improvement isn't exactly impressive. If the there's performance gained without additional power draw, that'll be great.
