Enjoy the View. - The AMD Radeon™ R9 Fury X GPU takes gaming to the next level, boasting 4096-bit high-bandwidth memory interface that not only meets but exceeds the extreme performance requirements for the most demanding 4K games for stunning performance in 4K resolutions and beyond8 with image quality settings turned up, smooth gaming with AMD FreeSync™ technology10, and is ready for the future with support for next-generation multi-threaded APIs including DirectX® 12, OpenGL® 4.5, Vulkan™ and AMD's Mantle.4,5,6
  Enabling new PC form factors. Small Size. Giant Impact. - The incredibly compact design of AMD Radeon™ R9 Fury X GPU opens the door for new and exciting PC form factors, with more design flexibility for modders, DIYers and System Integrators than ever before. The AMD Innovation Lab's recently unveiled Project Quantum prototype PC illustrates the point, making use of Radeon™ R9 Fury X GPUs to reinvent desktop computing for the VR era, enabling form factors never imagined before.
• A new family of the world's first HBM-powered GPUs - The AMD Radeon™ R9 Fury X, which is the world's first HBM-powered graphics card (previously codenamed "Fiji"), is scheduled for availability starting June 24th. The AMD Radeon R9 Fury, with both liquid- and air-cooled options, is slated for availability starting July 14th. The deceptively small (6" in length), category-creating AMD Radeon R9 Nano is scheduled to follow in Q3 2015. AMD also plans to bring to market this fall a flagship Radeon Fury product for very smooth 4K gaming and VR that is based on two "Fiji" GPUs.
