Graphics Core Next (GCN) is the codename for a family of graphics processing unit microarchitectures as well as the implemented instruction set developed by AMD and launched in 2011〔 〕 as the successor to TeraScale, which was introduced with the Radeon HD 2000 Series. GCN is used in 28 nm graphics chips in the HD 7700-7900, HD 8000, Rx 240-290, and Rx 300 series of AMD graphics cards. GCN is also used in the AMD Accelerated Processing Units code-named "Temash", "Kabini", "Kaveri", "Carrizo", "Beema" and "Mullins", as well as in Liverpool (PlayStation 4) and Durango (Xbox One). GCN is a RISC SIMD architecture contrasting the VLIW SIMD architecture of TeraScale. GCN requires considerably more transistors than TeraScale, but offers advantages for GPGPU computation. It makes the compiler simpler and should also lead to better utilization . GCN implements HyperZ.〔 (【引用サイトリンク】title=Feature matrix of the free and open-source "Radeon" graphics device driver )〕 An LLVM code generator (i.e. a compiler back-end) is available for Graphics Core Next. It is used e.g. by Mesa 3D. == Overall == As of September 2015 the family of microarchitectures implementing the identically called instruction set "Graphics Core Next" has seen three iterations. The differences in the instruction set are rather minimal, and microarchitectures also do not differentiate too much from one another. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Graphics Core Next」の詳細全文を読む スポンサード リンク
