AMD have finally shown off a public demonstration using the new hitman on DirectX 12 of their upcoming lineup of the radeon Polaris graphics cards. Running at 1440P, Hitman was demoed on Polaris 10 GPU.
AMD have also formally announced the radeon pro duo line up of graphics cards, two fury gpus on the same board, but with many of the features of their firepro lineup.
It would appear that AMD's roadmap shows off the radeon Vega lineup of graphics cards released in 2017 which will debut HBM2, with Navi to see a 2018 release. It's unknown what type of memory Radeon navi will use, only that will be next generation (possibly HBM3 or similar).
