AMD Radeon Rx 300 is a brand for a series of graphics cards. All used GPUs have been developed by AMD, produced in 28 nm and belong to the same microarchitecture family: Graphics Core Next (GCN).
Devices based on the Fiji architecture, which include the flagship AMD Radeon R9 Fury X along with the Radeon R9 Fury and Radeon R9 Nano, are the first GPUs to feature High Bandwidth Memory (HBM) technology which is faster and more power efficient than current GDDR5 memory. However, the Rx 300-numbered GPUs in the series are based on previous generation GPUs with revised power management and therefore only feature GDDR5 memory. The Radeon 300 series cards including the R9 390X were released on June 18, 2015. The flagship device, Fury X, was released on June 24, 2015, with the dual-GPU variant, the Radeon Pro Duo, being released the following year on April, 26th, 2016.
There are chips implementing all three iterations of Graphics Core Next. 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 1.1 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.
