If what AMD said is true, the Nano will be slower than a 290X.

The Nano uses 175W and Fiji offers "50% higher performance per Watt" compared to 290X. Given that the 290X uses 290W, the maths say that

Nano uses 60% of the 290X total power (175/290 = 0.6) plus 50% more performance per Watt = 0.6 x 1.5 = 0.90

So Nano gives about 90% of the performance of a 290X.

But the slide says "up to 2X higher performance per watt". Shouldnt it be more powerful than the 290x

Now I see where my mistake was. Fury X is 1.5x Perf/Watt while Nano is 2x Perf/Watt

With that, Nano should theoretically be between 20 and 27% faster than an R9 290X.
