The HD 8000 series is a family of computer GPUs developed by AMD. AMD was initially rumored to release the family in the second quarter of 2013, with the cards manufactured on a 28 nm process and making use of the improved Graphics Core Next architecture. However the 8000 series turned out to be an OEM rebadge of the 7000 series (although, Oland is of newer development).

Architecture
The Radeon HD 8000 series marked AMD's shift from VLIW (TeraScale) to RISC/SIMD architecture (Graphics Core Next). The newer, more powerful cards were equipped with GCN cores, the less powerful ones with older TeraScale2/3 cores, see table below. GCN desktop cards were code-named Southern Islands, while mobile ones were code-named Solar System.
OpenGL 4.x compliance requires supporting FP64 shaders. These are implemented by emulation on some TeraScale (microarchitecture) GPUs.
Multi-monitor support
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.
Video acceleration
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 (API)
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 (API)
API Vulkan 1.0 is supported for all with GCN Architecture. Vulkan 1.1 (GCN 2nd Gen. or 1.2 and higher) will be supported with actual drivers in 2018.
