Specs have been revealed for RX 500 series for the reference AMD RX 580 and the other partners. If the rumors are true and RX 580 is AMD answer to GTX 1070 and 1060 that means VEGA (mostly) on the right track to be AMD answer for GTX 1080/ti or even Titan XP.

I'm eager to see the official benchmarks the couple days coming.
