Products include the Radeon 7970 GHz Edition, Radeon HD 7970 and Radeon HD 7950.

Radeon HD 7900 Ĭodenamed Tahiti, the Radeon HD 7900 series was announced on December 22, 2011. While each bigger die has two additional memory controllers widening its bus by 128 bits, Pitcairn however has the same front-end dual tesselator units as Tahiti giving it similar performance to its larger brethren in DX11 tessellation benchmarks. Tahiti has a maximum ¼ double precision throughput relative to its single precision throughput, while the other two smaller consumer dies can only achieve a 1/16 ratio. While this gives roughly a doubling of single-precision floating point, there is however a significant departure in double-precision compute power. The 28 nm product line is divided in three dies ( Tahiti, Pitcairn, and Cape Verde), each one roughly doubling in shader units (32, 20 and 10 respectively). The die and package of a Radeon HD 7870 graphics card. Vulkan 1.2 is available for GCN 2nd Gen or higher with Windows Adrenalin 20.1(and newer) and Linux Mesa 20.0(and newer). Vulkan 1.1 is supported for all with GCN Architecture with recent drivers on Linux and Windows. or 1.2 and higher) For OpenCL 2.1 and 2.2 only Driver Updates are necessary with OpenCL 2.0 conformant Cards. OpenCL 2.0 is supported with GCN 2nd Gen. Open CL 1.0 to 1.2 are supported for all Chips with Terascale and GCN Architecture. OpenCL accelerates many scientific Software Packages against CPU up to factor 10 or 100 and more. Video acceleration īoth Unified Video Decoder (UVD) and Video Coding Engine (VCE) are present on the dies of all products and supported by AMD Catalyst and by the free and open-source graphics device driver#ATI/AMD. The AMD Eyefinity-branded on- die display controllers were introduced in September 2009 in the Radeon HD 5000 Series and have been present in all products since. On newer drivers Vulkan 1.1 on Windows and Linux is supported on all GCN-architecture based GPUs. These are implemented by emulation on some TeraScale (microarchitecture) GPUs. OpenGL 4.x compliance requires supporting FP64 shaders.A GPU implementing TeraScale (microarchitecture) version ' Northern Islands (VLIW4)' is found on APUs whose GPUs are branded with the Radeon HD 7000 series.A GPU implementing TeraScale (microarchitecture) version ' Evergreen (VLIW5)' is found on Radeon HD 7670 and below branded discrete GPUs.A GPU implementing Graphics Core Next is found on the Radeon HD 7730 and above branded discrete GPUs.Graphics Core Next was introduced with the Radeon HD 7000 Series. 5.2 Free and open-source graphics device driver 'Radeon'.5.1 AMD's proprietary graphics device driver 'Catalyst'.
