=== Software ===
AMD has made considerable efforts towards opening its software tools above the [[firmware]] level in the past decade.<ref>{{cite web|url=https://lists.freedesktop.org/archives/dri-devel/2015-April/081501.html |title=Initial amdgpu driver release |publisher=Lists.freedesktop.org |access-date=February 20, 2022}}</ref><ref>{{Cite web|url=https://www.phoronix.com/scan.php?page=news_item&px=Radeon-Rays-4.0-Going-Open|title=AMD Rethinks Decision And Will Open-Source Most Of Radeon Rays 4.0|website=phoronix.com}}</ref><ref>{{cite web |url=https://www.computer.org/publications/tech-news/heterogeneous-system-architecture/everything-you-need-to-know-about-why-amd-open-sourced-the-opencl-driver-stack-for-rocm |title=Everything You Need to Know About Why AMD Open Sourced the OpenCL Driver Stack for ROCm &#124; IEEE Computer Society |publisher=Computer.org |access-date=February 20, 2022 |archive-date=January 23, 2022 |archive-url=https://web.archive.org/web/20220123163432/https://www.computer.org/publications/tech-news/heterogeneous-system-architecture/everything-you-need-to-know-about-why-amd-open-sourced-the-opencl-driver-stack-for-rocm/ |url-status=dead }}</ref>

For the following mentions, software not expressely stated as being [[free software|free]] can be assumed to be [[proprietary software|proprietary]].

==== Distribution ====
[[AMD Radeon Software]] is the default channel for official software distribution from AMD. It includes both free and proprietary software components, and supports both [[Microsoft Windows]] and [[Linux]].

==== Software by type ====
==== CPU ====
* [[AMD Optimizing C/C++ Compiler|AOCC]] is AMD's optimizing proprietary C/C++ compiler based on LLVM and available for Linux.<ref>{{cite web|url=https://developer.amd.com/amd-aocc/ |title=AMD Optimizing C/C++ and Fortran Compilers (AOCC) – AMD |publisher=Developer.amd.com |access-date=February 20, 2022}}</ref>
* AMDuProf is AMD's CPU performance and Power profiling tool suite, available for Linux and Windows.<ref>{{cite web |title=NEW, AMD uProf 4.2 is now available|url=https://www.amd.com/en/developer/uprof.html|publisher=amd.com |access-date=June 19, 2024 |date=January 31, 2024}}</ref>
* AMD has also taken an active part in developing [[coreboot]], an open-source project aimed at replacing the proprietary BIOS firmware. This cooperation ceased in 2013, but AMD has indicated recently{{When|date=March 2021}} that it is considering releasing source code so that Ryzen can be compatible with coreboot in the future.<ref>{{Cite web|url=https://www.golem.de/news/freie-firmware-amd-prueft-coreboot-support-fuer-ryzen-1703-126524.html|title=AMD prüft Coreboot-Support für Ryzen|website=golem.de}}</ref>

==== GPU ====
{{See also|AMD Radeon Software}}
Most notable public AMD software is on the GPU side.

AMD has opened both its [[computer graphics|graphic]] and [[General-purpose computing on graphics processing units|compute]] stacks:
* [[GPUOpen]] is AMD's graphics stack, which includes for example FidelityFX Super Resolution.
* [[ROCm]] (Radeon Open Compute platform) is AMD's compute stack for [[machine learning]] and [[Supercomputer|high-performance computing]], based on the [[LLVM|LLVM compiler]] technologies. Under the ROCm project, [[AMDgpu (Linux kernel module)|AMDgpu]] is AMD's [[free and open-source graphics device driver|open-source]] [[device driver]] supporting the [[Graphics Core Next|GCN]] and following architectures, available for Linux. This latter driver component is used both by the graphics and compute stacks.

* AMD conducts open research on [[heterogeneous computing]].<ref>{{cite web|url=https://www.amd.com/en/corporate/research-opensource|title=AMD research Open-Source Projects|website=Amd.com|access-date=February 21, 2022}}</ref>
* Other AMD software includes the [[AMD Core Math Library]], and open-source software including the [[AMD Performance Library]].
* AMD contributes to [[Open-source software|open-source]] projects, including working with [[Sun Microsystems]] to enhance [[OpenSolaris]] and [[Sun xVM]] on the AMD platform.<ref>{{Cite press release |title=AMD Expands Charter for the OpenSolaris OS and Sun xVM at the AMD Operating System Research Center |date=May 5, 2008 |publisher=AMD |url=https://www.amd.com/gb-uk/Corporate/VirtualPressRoom/0,,51_104_543~125446,00.html |archive-url=https://web.archive.org/web/20090116054951/http://www.amd.com/gb-uk/Corporate/VirtualPressRoom/0%2C%2C51_104_543~125446%2C00.html |archive-date=January 16, 2009 |url-status=dead }}</ref> AMD also maintains its own [[Open64]] compiler distribution and contributes its changes back to the community.<ref>{{cite web |date=July 28, 2015 |title=x86 Open64 Compiler Suite |url=http://developer.amd.com/tools-and-sdks/cpu-development/x86-open64-compiler-suite/ |url-status=dead |archive-url=https://web.archive.org/web/20131113100944/http://developer.amd.com/tools-and-sdks/cpu-development/x86-open64-compiler-suite/ |archive-date=November 13, 2013 |publisher=AMD }}</ref>
* In 2008, AMD released the low-level programming specifications for its [[GPU]]s, and works with the [[X.Org Foundation]] to develop drivers for AMD graphics cards.<ref>{{Cite press release |title=AMD Details Strategic Open Source Graphics Driver Development Initiative |date=September 7, 2007 |publisher=AMD |url=https://www.amd.com/us-en/Corporate/VirtualPressRoom/0,,51_104_543~119372,00.html}}</ref><ref>{{cite web |title=Index of /docs/AMD |url=http://www.x.org/docs/AMD/ |publisher=[[X.Org Foundation|x.org]]}}</ref>
* Extensions for software parallelism (xSP), aimed at speeding up programs to enable multi-threaded and multi-core processing, announced in Technology Analyst Day 2007. One of the initiatives being discussed since August 2007 is the Light Weight [[Profiling (computer programming)|Profiling]] (LWP), providing internal hardware monitor with runtimes, to observe information about executing process and help the re-design of software to be optimized with multi-core and even multi-threaded programs. Another one is the extension of Streaming SIMD Extension (SSE) instruction set, the [[SSE5]].
* Codenamed ''SIMFIRE'' – interoperability testing tool for the Desktop and mobile Architecture for System Hardware (DASH) [[open architecture]].
