Yesterday AMD released its Q3 2018 earnings. Sales and profits increased again despite losses in the GPU market.
AMD allegedly plans a new version of Polaris as Polaris 30 with 12nm structure width. A leaked RX 590 with benchmark confirms this.
The Polaris series from AMD will have a refresh. The successors of the RX 570 and RX 580 will be made in 12nm and will start in October and November.
