Here is their conclusion:
As for the competitive landscape then, AMD’s situation has improved, though I fear by not enough. Across the full spread of games in our benchmark suite, the RX 580 and GTX 1060 6GB change lead a few different times, so the RX 580 is able to best NVIDIA’s best in absolute performance in the right games. The problem for AMD is that those games appear to be too few; as a result the RX 580 trails the GTX 1060 by an average of 7% at both 1080p and 1440p. AMD has narrowed the gap somewhat – this was an 11% deficit with the RX 480 – but not by enough. And coupled with AMD’s worse power efficiency, this puts AMD in a tough spot. The biggest challenge right now is that GTX 1060 prices have come down to the same $229 spot just in time for the RX 500 series launch, so AMD doesn’t have a consistent price advantage.
