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

The exact quote seems to vary from site to site. So, depends on the exact quote, Nano will be either 10% slower than a 290X or 20% faster.

Edit: Also, the 290X is officially a 275W card. Taking that number, the Fury Nano could be between 5% slower than a 290X or 27% faster.
