According to Fudzilla, AMD's upcoming 7nm Navi GPU will not be a gaming part and only provide performance equivalent to a GeForce GTX 1080. A high-end successor is not expected until 2020, at earliest. Navi 7nm won’t have two different SKUs, one that miraculously goes after the Geforce Turing edition planned for later this year. So, the long story short, AMD won’t have anything in the high-end space faster than Vega between now and end of 2019. In GPU world, this is eternity.
