AMD planned well in advance for the future when they introduced GCN as the replacement to TeraScale (their previous VLIW architecture). Not only is it a potent platform for GPU compute—making it very popular for cryptocurrency hashing—but graphics cards as far back as the Radeon HD 7000 series, released in 2012, have support for DX12, Mantle and Vulkan and see significant performance gains when using them. Unlike Nvidia's most recent cards which, despite having support for these APIs, see very little improvement when using them.
