GDC 2016 - AMD is beginning to show its hand when it comes to its GPU roadmap, with the company unveiling its GPU architecture roadmap at its Capsaicin event at GDC 2016.
We now know that AMD will be pushing out its next-gen Polaris architecture later this year, but now we know that Vega and Navi will be coming out in 2017 and 2018, respectively. The only details we know on Vega is that it will feature HBM2, while Navi notes "scalability" and "nexgen memory" - I hope AMD meant "next-gen memory", there.
In an interview with Ryan Shrout from PC Perspective, RTG boss Raja Koduri hinted that Polaris might be using HBM1 instead of HBM2, and this new GPU roadmap makes that seem like an actual possibility. Considering AMD make a specific mention that Vega uses HBM2, it makes sense that Polaris could be more of a mid-range part, versus an enthusiast part. But I personally sat down with AMD's Roy Taylor, and asked him just that - will we see an enthusiast Polaris part, to which he said we should wait until later in the year.
