While it's not a gaming chip it's good news that 7 nm is not to far away. Hopefully see Navi in early 2019 and not late 2019. Still it would be good to see something before then as i think Nvidia will take an even bigger lead performance wise within the next 3 months.
Samples of Vega20 are going to partners this year, which means Vega20 sales will begin early 2019. Navi won't come so fast after Vega20, earliest 3 Months. If they launch V20 in 2018, then Navi might come early 2019, but AMDs own projections are all saying something else. So i'm sure we won't see Navi before mid 2019 around Computex.
