AMD has unleashed a bunch of new products today at their Financial Analyst Day, with a tease of ThreadRipper with 16C/32T, their new Naples platform and the Epyc CPU with 32C/64T, and the exciting new Radeon Vega Frontier Edition graphics card.
AMD also detailed their GPU roadmap through to 2020, with Vega arriving on 14nm - but a 14nm+ respin that I think we'll see in early 2018. The bigger tease is Navi on 7nm for 2018-2019, and a brief glimpse of 'Next Gen' sometime in 2019-2020.
