TypeDevice driver and management

AMD Radeon Software is a device driver and utility software package for AMD's Radeon graphics cards and APUs. Its graphical user interface is built with Electron and is compatible with 64-bit Windows and Linux distributions.

Software bundle[edit]


Radeon Software includes the following feature set:

  • Game profile management
  • Overclocking and undervolting
  • Performance monitoring
  • Recording and streaming
  • Captured video and screenshot management
  • Software update notifications
  • Upgrade advisor

Radeon Anti-Lag reduces input latency. It helps when the GPU is bottlenecking the CPU[6] and is supported in DirectX 9, 11, and 12.[7] Radeon Super Resolution is image upscaling technology similar to FidelityFX Super Resolution (FSR), but it does not have to be customized for specific games. It works on thousands of games, but AMD recommends using FSR when available.[8] Radeon Boost also uses image upscaling to increase performance, but unlike AMD's other technologies, it does this only at certain times, such as when rapidly moving the mouse. This is interpreted as an action-heavy scene where image quality can temporarily be decreased without much noticeable effect.[9] This only works in supported games.[6] HYPR-RX is a planned feature that will enable Radeon Anti-Lag, Boost, and Super Resolution with a single keystroke. As of July 2023, it has not yet been implemented.[10]

Radeon Chill lowers performance when the AMD drivers detect idle moments in games and can set frame rate caps.[6] Smart Access Memory enables potential performance boosts on systems that use both AMD Ryzen CPUs and Radeon video cards.[6] Radeon Enhanced Sync reduces screen tearing like vsync, but it avoids capping frame rates at the monitor's refresh rate. This can reduce the input lag associated with vsync. This is limited to DirectX 9, 10, and 12.[11] AMD Link allows users to stream content to mobile devices, compatible Smart TVs,[b] and other PCs with Radeon video cards. The client requires a free app, which is available via Google Play, Apple App Store, and Amazon Appstore.[13]


The software was previously known as AMD Radeon Settings, AMD Catalyst, and ATI Catalyst. AMD ceased providing 32-bit versions in October 2018.

Supported hardware[edit]

AMD Radeon Software is targeted to support all function blocks present on a GPU's or an APU's die. Besides instruction code targeted at rendering, this includes display controllers as well as their SIP blocks for video decoding (Unified Video Decoder (UVD)) and video encoding (Video Coding Engine (VCE)).

The device driver also supports AMD TrueAudio, a SIP block to perform sound-related calculations.

Supported products[edit]

AMD Radeon Software supports the following AMD (and ATI-tradition) product lines targeted at rendering:

The following product lines are probably[original research?] not supported by the AMD Radeon Software, but instead by some other software, which (for example) is OpenGL-certified:

  • AMD FireStream product line for GPGPU in supercomputers and such
  • AMD FireMV product line for multi-monitor setups (deprecated by AMD Eyefinity being available on all consumer products)[citation needed]
  • AMD FirePro product line for professionals who require certified OpenGL support

Multi-monitor support[edit]

Starting in Catalyst 14.6 AMD has enabled mixed-resolution support, allowing for a single Eyefinity display group to be created where each monitor runs at a different resolution. The current version may, however, disable any additional display mode and change to a resolution in the one mode available. This feature is made possible through the addition of two new Eyefinity display modes, Fit and Expand, which join the traditional Fill mode. In both Fit and Expand modes, AMD is compensating for the mismatched resolutions by creating a virtual desktop that is of a different resolution from those of the monitors, and then either padding it out or cropping it as necessary.[14]

Before Eyefinity, there was the Windows-only software "HydraVision"[15] (originally acquired from Appian Graphics complete with its development team), a desktop/screen management software mostly providing multi-monitor and virtual-screen management. It has extensive hot-key support.[16]

Video acceleration[edit]

Both of AMD's SIP cores for video acceleration, Video Coding Engine as well as Unified Video Decoder, are supported by AMD Radeon Software.

Audio acceleration[edit]

Some AMD products contain SIP cores for audio acceleration branded AMD TrueAudio. Support for this audio acceleration DSP co-processor is part of AMD Radeon Software.

Under Microsoft Windows the support for AMD TrueAudio is codenamed "ACP" (for audio co-processor) and implemented via "ACP user service" (amdacpusrsvc.exe), a background service that helps manage audio tasks in games.

Under Linux, AMD TrueAudio is codenamed "acp" as well: some code regarding this can be found in the /drivers/gpu/drm/radeon directory of the Linux kernel sources.

Power saving[edit]

AMD Radeon Software includes support for AMD PowerPlay, AMD PowerTune and AMD ZeroCore Power, AMD's set of technologies to reduce energy consumption in their graphics products.[17]

Supported interfaces[edit]


The AMD Radeon Software device driver supports multiple rendering interfaces, all designed to give the user-space programs, such as video games or CAD software, access to the corresponding SIP blocks.


Direct3D 12 is available for GCN with version 15.7.1 or higher.[18]


Only the Radeon Software targeting Microsoft Windows included support for Mantle. In 2019 starting with version 19.5.1 it was officially discontinued, in favor of DirectX 12 and Vulkan (built upon Mantle) raise in popularity.[19] Windows users who still wish to use Mantle would have to use older version of drivers (prior to 19.5.1).[20]


OpenGL 4.5 is possible for TeraScale 2 and 3 with AMD Radeon Software Crimson Edition Beta (driver version 15.30 or higher like Crimson Beta 16.2.1).[21][22] OpenCL support will be lost, but it can be recovered by copying the relevant files from a previous package like Radeon Software 15.11.1 Beta. Beta drivers do not support HDCP.

OpenGL 4.5 is available for GCN with version 16.3 or higher.[23]

OpenGL 4.x compliance requires supporting FP64 shaders. These are implemented by emulation on some TeraScale GPUs.

OpenGL 4.6 is supported in AMD Adrenalin 18.4.1 Graphics Driver on Windows 7 SP1, 10 version 1803 (April 2018 update) for AMD Radeon HD 7700+, HD 8500+ and newer. Released April 2018.[24][25]


Vulkan 1.0 is available with AMD Radeon Software Crimson Edition 16.3.2 or higher for GCN.[26]

Vulkan 1.1 with AMD Radeon Software Adrenalin Edition 18.3.3 or higher.[27]

Vulkan 1.2 with Adrenalin 20.1.2 or higher.[28]

Vulkan 1.3 with Adrenalin 22.1.2 or higher.[29]

Video acceleration[edit]

The AMD Radeon Software device driver supports multiple interfaces, all designed to give user-space programs, such as GStreamer or HandBrake software, access to the corresponding SIP blocks.




With Catalyst 9.12 support of OpenCL 1.0 was available.[30]

In Catalyst 10.10 OpenCL 1.1 was available.[31]

Catalyst 12.4 Supports OpenCL 1.2.[32]

OpenCL 2.0 driver works since 14.41 for GCN-based Models.[33] This also supports previous OpenCL versions.

TeraScale 2 and 3 chips can use Level 1.2.

Close to Metal[edit]

Close to Metal was a low-level API by AMD which was abandoned in favor of OpenCL.


AMD HD3D stereoscopic 3D API by AMD.

Heterogeneous System Architecture (HSA)[edit]

With Catalyst 14.1 HSA is possible.[34] AMD main Processor graphic Units and Radeon graphic Card Units work combined.

AMD GPU Services (AGS)[edit]

AMD Display Library (ADL) SDK[edit]

Operating systems support[edit]


The main AMD GPU software stacks are fully supported on Linux: GPUOpen for graphics, and ROCm for compute. GPUOpen is most often merely a supplement, for software utilities, to the free Mesa software stack that is widely distributed and available by default on most Linux distributions.

AMD strives at packaging its software for Linux on its own, not relying solely on Linux distributions. They do so by using the amdgpu and amdgpu-pro shell scripts, and provide package archives for e.g. apt and rpm.[35]

Microsoft Windows[edit]

Starting with version 4.9 (released on 4 September 2004) the Catalyst driver package included the ATI Catalyst Control Center,[44] a new software application for manipulating many hardware functions, such as 3D settings, monitor controls and video options. It shows a small 3D preview and allows the user to see how changes to the graphics settings affect the quality of the rendered image. It also shows information about the card itself and the software data. This application requires Microsoft .NET Framework.
