ROCm [3] is an Advanced Micro Devices (AMD) software stack for graphics processing unit (GPU) programming. ROCm spans several domains: general-purpose computing on graphics processing units (GPGPU), high performance computing (HPC), heterogeneous computing.
AMD Software (formerly known as 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 Qt [ 6 ] and is compatible with 64-bit Windows and Linux distributions .
AMD were light on concrete details surrounding the RDNA 4 architecture or the Radeon RX 9000 series during their CES keynote. [5] The Radeon RX 9000 series targets midrange performance and value rather than competing with Nvidia at the high-end like the Radeon RX 7000 series did. [6] This is a similar approach taken by the RX 5000 series in 2019.
AMDgpu is an open source device driver for the Linux operating system developed by AMD to support its Radeon lineup of graphics cards (GPUs). It was announced in 2014 as the successor to the previous radeon device driver as part of AMD's new "unified" driver strategy, [3] and was released on April 20, 2015.
Nicolas Thibieroz, AMD's Senior Manager of Worldwide Gaming Engineering, argues that "it can be difficult for developers to leverage their R&D investment on both consoles and PC because of the disparity between the two platforms" and that "proprietary libraries or tools chains with "black box" APIs prevent developers from accessing the code for maintenance, porting or optimizations purposes".

The basic DMA-BUF PRIME infrastructure was finished in March 2012 [166] and merged into the Linux 3.4 release, [167] [168] [169] as well as into libdrm 2.4.34. [170] Later during the Linux 3.5 release, several DRM drivers implemented PRIME support, including i915 for Intel cards, radeon for AMD cards and nouveau for NVIDIA cards. [171] [172]
The ROM also contained a basic font set [5] to upload to the video adapter font RAM, if the video card did not contain a font ROM with this font set instead. Unlike some other hardware components, the video card usually needs to be active very early during the boot process so that the user can see what is going on.
Unified Video Decoder (UVD, previously called Universal Video Decoder) is the name given to AMD's dedicated video decoding ASIC. There are multiple versions implementing a multitude of video codecs, such as H.264 and VC-1. UVD was introduced with the Radeon HD 2000 Series and is integrated into some of AMD's GPUs and APUs.
