Radeon HD 7000 series
The Radeon HD 7000 series, codenamed "Southern Islands", is a family of GPUs developed by AMD, and manufactured on TSMC's 28 nm process.
The primary competitor of Southern Islands was Nvidia's GeForce 600 series (also manufactured at TSMC), which shipped during Q1 2012, largely due to the immaturity of the 28 nm process.
Graphics Core Next was introduced with the Radeon HD 7000 series.
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.
Both 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.
OpenCL accelerates many scientific Software Packages against CPU up to factor 10 or 100 and more. Open CL 1.0 to 1.2 are supported for all Chips with Terascale and GCN Architecture. OpenCL 2.0 is supported with GCN 2nd Gen. or 1.2 and higher. For OpenCL 2.1 and 2.2 only Driver Updates are necessary with OpenCL 2.0 conformant Cards.
Vulkan 1.1 is supported for all with GCN Architecture using recent drivers on both Linux and Windows. Vulkan 1.2 is available for GCN 2nd Gen or higher with Windows Adrenalin 20.1(and newer). Vulkan 1.3 is available for GCN 1st Gen and higher with Mesa RADV on Linux.
The 28 nm product line is divided in three dies (Tahiti, Pitcairn, and Cape Verde), each one highly increasing shader units (32, 20 and 10 respectively). While this gives a high increase in single-precision floating point, there is however a significant departure in double-precision compute power. 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 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.
