Radeon 300 series
The Radeon 300 series is a series of graphics processors developed by AMD. All of the GPUs of the series are produced in 28 nm format and use the Graphics Core Next (GCN) micro-architecture.The second 8GB Radeon graphics card in the series has been released.
The series includes the Fiji and Tonga GPU dies based on AMD's GCN 3 or "Volcanic Islands" architecture, which had originally been introduced with the Tonga based (though cut-down) R9 285 slightly earlier. Some of the cards in the series include the Fiji based flagship AMD Radeon R9 Fury X, cut-down Radeon R9 Fury and small form factor Radeon R9 Nano, which are the first GPUs to feature High Bandwidth Memory (HBM) technology, which AMD co-developed in partnership with SK Hynix. HBM is faster and more power efficient than GDDR5 memory, though also more expensive. However, the remaining GPUs in the series outside the Tonga based R9 380 and R9 380X are based on previous generation GPUs with revised power management, and therefore only feature GDDR5 memory (something Tonga does as well). The Radeon 300 series cards including the R9 390X were released on June 18, 2015. The flagship device, the Radeon R9 Fury X, was released on June 24, 2015, with the dual-GPU variant, the Radeon Pro Duo, being released on April 26, 2016.
The R9 380/X along with the R9 Fury & Nano series were AMD's first cards (after the earlier R9 285) to use the third iteration of their GCN instruction set and micro-architecture. The other cards in the series feature first and second gen iterations of GCN. The table below details which GCN-generation each chip belongs to.
Any ancillary ASICs present on the chips are being developed independently of the core architecture and have their own version name schemes.
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.
AMD TrueAudio was introduced with the AMD Radeon Rx 200 series, but can only be found on the dies of GCN 2nd gen and later products.
AMD's SIP core for video acceleration, Unified Video Decoder and Video Coding Engine, are found on all GPUs and are supported by AMD Catalyst and by the open-source Radeon graphics driver.
A new feature to the lineup allows users to reduce power consumption by not rendering unnecessary frames. It is user configurable.
