The Radeon 400 series is a series of graphics processors developed by AMD. These cards were the first to feature the Polaris GPUs, using the new 14 nm[8] FinFET manufacturing process, developed by Samsung Electronics and licensed to GlobalFoundries. The Polaris family initially included two new chips in the Graphics Core Next (GCN) family (Polaris 11 and Polaris 12). Polaris implements the 4th generation of the Graphics Core Next instruction set, and shares commonalities with the previous GCN microarchitectures.
