The best news about this probably is the fact that the rumors of these cards being GCN are false, this is a new architecture known as RDNA, or Radeon DNA.
Why that is good, the redesign means a noticeably higher performance per-clock and a significant reduction in power consumption per-clock. In addition, this has more cache and will come with industry-proven GDDR6 memory rather than HBM.
The card shown in the presentation is designed to go up against the GTX 2070, with AMD claiming a 10 percent performance advantage.
I have to say, the confirmed information means Navi is better than I feared it could’ve been, they could have a winner if only we see an equivalent bump in their driver quality. At the least, there’s a chance this could drive GPU prices down to more reasonable levels
