The Southern Islands series is a family of Radeon GPUs developed by AMD.[1] AMD builds Southern Islands series graphics chips based on the 28 nm manufacturing process at TSMC.[2] The Southern Islands design was reportedly taped out in February 2011.[citation needed] AMD gave a preview of the new design at the AMD Fusion Development Summit (June 13–16, 2011).[3] On July 21, 2011, the company confirmed that it has working silicon in-house and it plans to release the first cards before the end of the year,[4] the primary constraint being the stability of the 28 nm process at TSMC.[5] The primary competitor of Southern Islands, Nvidia's GeForce 600 Series (also manufactured at TSMC), also shipped during Q1 2012, largely due to the immaturity of the 28 nm process.[clarification needed][6]

Features [edit]

In 2010, the Northern and Southern Islands cards adopted the AMD Radeon brand name. text-Southern Islands GPUs are branded as the Radeon HD 7000 Series.[citation needed]

Technical details [edit]

Southern Islands architecture had the code name "Graphics Core Next" (GCN).[7][not in citation given]

  • Support for x86 addressing with unified address space for CPU and GPU.
  • Usage of RISC SIMD instructions for GPGPU instead of VLIW MIMD (Which was only one option in previous AMD GPU-architectures).
  • Support for Partially Resident Textures,[9] which enable virtual memory support through DirectX and OpenGL extensions.
  • PowerTune support, which dynamically adjusts performance to stay within a specific TDP.
  • Usage of Liquid-chamber cooling technology over Vapor chamber.[10]

These changes could lead to better utilization of the GPU for compute along with traditional graphics.

It is noteworthy that, as opposed to the Evergreen and Northern Islands GPU Families, the Southern Islands GPU Family has only 4 chips instead of 5, omitting the lowest end one (resp. Cedar and Caicos in previous families). This change is due to this GPU segment now being served by the integration of AMD's APUs.[citation needed]

Products [edit]

The 28 nm product line is divided in three dies (Tahiti, Pitcairn, and Cape Verde), each one roughly double in shader units compared to its small brethren (32, 20, and respectively 10 GCN compute units). While this gives roughly a doubling of 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.[11] 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.[11]

Radeon HD 7900 [edit]

Codenamed Tahiti, the Radeon HD 7900 series was announced on December 22, 2011. Products include the Radeon 7970 GHz Edition, Radeon HD 7970 and Radeon HD 7950. The Radeon HD 7970 features 2048 usable stream cores, whereas the Radeon HD 7950 has 1792 usable stream cores, as 256 out of the 2048 cores are disabled during product binning which detects defective areas of a chip. The cards are the first products to take advantage of AMD's new "Graphics Core Next" compute architecture. Both cards are equipped with 3 GB GDDR5 memory and manufactured on TSMC's 28 nm process. The Tahiti GPU is also used in the Radeon HD 7870 XT, released November 19th, 2012. In this case one quarter of the stream processors are disabled, giving 1536 usable cores. Additionally, the memory interface is downgraded from 384-bit to 256-bit, along with a memory size reduction from 3 GB to 2 GB.

Radeon HD 7800 [edit]

Codenamed Pitcairn, the Radeon HD 7800 series was formally unveiled on March 5, 2012, with retail availability from March 19, 2012. Products include the Radeon HD 7870 and Radeon HD 7850. The Radeon HD 7870 features 1280 usable stream cores, whereas the Radeon HD 7850 has 1024 usable stream cores. Both cards are equipped with 2 GB GDDR5 memory and manufactured on TSMC's 28 nm process.[12]

Radeon HD 7700 [edit]

Codenamed Cape Verde, the Radeon HD 7700 series was released on February 15, 2012. Products include the Radeon HD 7770 GHz Edition and Radeon HD 7750. The Radeon HD 7770 GHz Edition features 640 usable stream cores, whereas the Radeon HD 7750 has 512 stream cores based on the GCN architecture. Both cards are equipped with 1 GB GDDR5 memory and manufactured in 28 nm. The Radeon 7790 series was released on March 22 2013 and led to the removal of the 7850 1GB from AMDs lineup. The 7790 is based on the Bonaire architecture, AMD's GCN 1.1 architecture, as opposed to the Pitcairn and 1.0 of the 7750 and 7770.

Chipset table [edit]

Southern Islands (HD 7xxx) series [edit]

  • All models up to including HD 76xx based on VLIW5 architecture, HD 77xx-79xx are based on GCN (Graphics Core Next) architecture.
  • HD 73xx-76xx models support DirectX 11, OpenGL 4.3 and OpenCL 1.2
  • HD 77xx-79xx models support DirectX 11.1, OpenGL 4.3 and OpenCL 1.2
  • HD 7790 model include DirectX 11.1, OpenGL 4.3 and OpenCL 1.2
  • HD 7790 model is designed more like the 7800/7900 models rather than the 7700 featuring 2x primitive rate instead of 1x which is found in the other 7700 cards.[13]
  • Bonaire is in the Caribbean Sea, Malta is in the Mediterranean Sea these parts are reverse rebranded out of the Sea Island series to appear in the 7000 series this year.
