In that review the 1070 draw less power!! lol.
"It's a creditable enough showing from AMD, but it is put into shade somewhat by the phenomenal result of the GTX 1070 - it's in an altogether different league in terms of performance and yet it offers the same ballpark consumption as the RX 480. This is perhaps not surprising bearing in mind that both cards are based on a 150W TDP."
