amd pretty much said mantle is probably going to phase out. it does the same thing as dx12. mantle pretty much paved the way and pushed out dx12.

Although AMD has had unexpected success with developers adopting Mantle, it was unlikely to become a standard without the support of its chief competitor Nvidia. When Microsoft announced DirectX 12, which adopted features of Mantle, AMD's API looked to be a technological dead end

The future of AMD's Mantle API is not clear, but to be frank it may have already served it's purpose. The development of DirectX 12 and Vulcan have undoubtedly been heavily influenced by Mantle, both have focused on the main inefficiencies of OpenGL and DirectX 11 which Mantle had addressed, so now is maybe the time for AMD to back away from the API game.
