That was compared to their own cards which were notoriously bad in efficiency. The new architecture didn't do much in that regards and the efficiency gain is almost exclusively due to the shrink.

Yeah I know but it still isn't true.

A 290/390 draws 275W and a 480 draws 160W at top speed, and if the 480 is 10% faster, the perf per Watt becomes only x1.9. Although I should use the Fury cards in this comparison, correct? Then it becomes even worse for AMD.

Well okay, it's not that far from what was advertized. But like you say, they had so much catching up to do versus Nvidia.

Still almost a whole generation behind. It's painful to be an AMD fan.

The Vega must beat a 1080 at least, because by then there'll be a 1080 Ti and I want my next PC to be top class.

That's because the Rx 480 isn't running at it's ideal speed, setting the Powertune to -20% lowers the power draw with 30W while only lowering the performance by 5%:

That means that the card is still faster than a 290/390 while only drawing about 120-130W. And it's a new card so performance will improve overtime with new drivers. So 2.5x improved in some cases is possible. Personally i'm curious about the RX 470, if that one overclocks decently it could be a a lot of value for the money.
