Radeon 300 series

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. == Ancillary ASICs ==

Ancillary ASICs present on the chips are being developed independently of the core architecture and have their own version name schemes. Multi-monitor support 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 AMD TrueAudio was introduced with the AMD Radeon RX 200 series for audio processing. It is only found on the dies of GCN 2nd gen and later products. Video acceleration 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. Frame limiter A new feature to the lineup allows users to reduce power consumption by not rendering unnecessary frames. It is user configurable. LiquidVR support LiquidVR is a technology that improves the smoothness of virtual reality. The aim is to reduce latency between hardware so that the hardware can keep up with the user's head movement, eliminating the motion sickness. A particular focus is on dual GPU setups where each GPU now renders for one eye individually of the display. Virtual super resolution support Originally introduced with the previous generation R9 285 and R9 290 series graphics cards, this feature allows users to run games with higher image quality by rendering frames at above native resolution. Each frame is then downsampled to native resolution. This process is an alternative to supersampling which is not supported by all games. Virtual super resolution is similar to Dynamic Super Resolution, a feature available on competing Nvidia graphics cards, but trades flexibility for increased performance. OpenCL (API) OpenCL accelerates many scientific Software Packages against CPU up to factor 10 or 100 and more. Open CL 1.0 to 1.2 are supported for all chips with Terascale and GCN Architecture. OpenCL 2.0 is supported with GCN 2nd Gen. and higher. For OpenCL 2.1 and 2.2, only driver updates are necessary with OpenCL 2.0 conformant Cards. Vulkan (API) Vulkan 1.0 is supported for all GCN architecture cards. Vulkan 1.2 requires GCN 2nd gen or higher with the Adrenalin 20.1 and Linux Mesa 20.0 drivers and newer. ==Chipset tables==

Proprietary graphics device driver Catalyst AMD Catalyst is being developed for Microsoft Windows and Linux. As of July 2014, other operating systems are not officially supported. This may be different for the AMD FirePro brand, which is based on identical hardware but features OpenGL-certified graphics device drivers. AMD Catalyst supports all features advertised for the Radeon brand. Free and open-source graphics device driver radeon The free and open-source drivers are primarily developed on and for Linux, but have been ported to other operating systems as well. Each driver is composed out of five parts: • Linux kernel component DRM • Linux kernel component KMS driver: basically the device driver for the display controller • user-space component libDRM • user-space component in Mesa 3D • a special and distinct 2D graphics device driver for X.Org Server, which is finally about to be replaced by Glamor The free and open-source radeon kernel driver supports most of the features implemented into the Radeon line of GPUs. This driver still requires proprietary microcode to operate DRM functions and some GPUs may fail to launch the X server if not available. Free and open-source graphics device driver amdgpu This new kernel driver is directly supported and developed by AMD. It is available on various Linux distributions, and has been ported to some other operating systems as well. Only GCN GPUs are supported. The driver has been experimentally ported to ArchLinux and other distributions. AMDGPU-PRO is set to replace the previous AMD Catalyst driver and is based on the free and open source amdgpu kernel driver. Pre-GCN GPUs are not supported. == See also ==
