The Southern Islands series is a family of GPUs developed by Advanced Micro Devices.[1] Products are expected to be released in the second half of 2011. Products in the Southern Islands series will be based on the 28 nm manufacturing process. AMD will build 28 nm graphics chips at TSMC.[2]
Early details
In 2010, the Northern and Southern Islands cards adopted the AMD Radeon brand name. The Southern Islands will most likely be named the Radeon HD 7000 Series.
Technical details
Early rumors said this this series would only be a die-shrink of the Radeon HD 6900 (Cayman) architecture.[3] However, later news revealed that the Southern Islands architecture is called Graphics Core Next Gen. [4]
- Support for x86 addressing with unified address space for CPU and GPU.
- Usages of MIMD instructions instead of VLIW (Which was used in previous AMD GPU-architectures).
- Support for Partially Resonant Textures, which enabled virtual memory support through DirectX and OpenGL extensions.
- PowerTune support, which dynamically adjusts performance to stay within a specific TDP.
These changes could lead to better utilization of the GPU for compute along with traditional graphics.
This architecture is supposed to be integrated into the next line of AMD Fusion processors.
Release date
The Southern Island family is to enter mass production in May 2011,[6] with the first samples shown at the AMD Fusion Development Summit (June 13-16, 2011).[7]
