History
PredecessorRage

Radeon (/ˈreɪdiɒn/) is a brand of computer products, including graphics processing units, random-access memory, RAM disk software, and solid-state drives, produced by Radeon Technologies Group, a division of AMD.[1] The brand was launched in 2000 by ATI Technologies, which was acquired by AMD in 2006 for US$5.4 billion.

Radeon Graphics

[edit]

Radeon Graphics is the successor to the Rage line. Four different families of microarchitectures can be roughly distinguished, the fixed-pipeline family, the unified shader model-families of TeraScale, Graphics Core Next, and RDNA. ATI/AMD have developed different technologies, such as TruForm, HyperMemory, HyperZ, XGP, Eyefinity for multi-monitor setups, PowerPlay for power-saving, CrossFire (for multi-GPU) or Hybrid Graphics. A range of SIP blocks is also to be found on certain models in the Radeon products line: Unified Video Decoder, Video Coding Engine and TrueAudio.

The brand was previously only known as "ATI Radeon" until August 2010, when it was renamed to increase AMD's brand awareness on a global scale.[2] Products up to and including the HD 5000 series are branded as ATI Radeon, while the HD 6000 series and beyond use the new AMD Radeon branding.[3]

On 11 September 2015, AMD's GPU business was split into a separate unit known as Radeon Technologies Group, with Raja Koduri as Senior Vice President and chief architect.[1][4]

Radeon graphics card brands

[edit]

AMD does not distribute Radeon cards directly to consumers (though some exceptions can be found).[5] Instead, it sells Radeon GPUs to third-party manufacturers, who build and sell the Radeon-based video cards to the OEM and retail channels. Manufacturers of the Radeon cards—some of whom also make motherboards—include ASRock, Asus, Biostar, Club 3D, Diamond, Force3D, Gainward, Gigabyte, HIS, PowerColor, Sapphire, VisionTek, and XFX.

Early generations were identified with a number and major/minor alphabetic prefix. Later generations were assigned code names. New or heavily redesigned architectures have a prefix of R (e.g., R300 or R600) while slight modifications are indicated by the RV prefix (e.g., RV370 or RV635).

The first derivative architecture, RV200, did not follow the scheme used by later parts.

Fixed-pipeline family

[edit]

R100/RV200

[edit]
Main article: Radeon R100 series

The Radeon, first introduced in 2000, was ATI's first graphics processor to be fully DirectX 7 compliant. R100 brought with it large gains in bandwidth and fill-rate efficiency through the new HyperZ technology.

The RV200 was a die-shrink of the former R100 with some core logic tweaks for clockspeed, introduced in 2002. The only release in this generation was the Radeon 7500, which introduced little in the way of new features but offered substantial performance improvements over its predecessors.

R200

[edit]
Main article: Radeon R200 series

ATI's second generation Radeon included a sophisticated pixel shader architecture. This chipset implemented Microsoft's pixel shader 1.4 specification for the first time.

Its performance relative to competitors was widely perceived as weak, and subsequent revisions of this generation were cancelled to focus on development of the next generation.

R300/R350

[edit]
Main article: Radeon R300 series

The R300 was the first GPU to fully support Microsoft's DirectX 9.0 technology upon its release in 2001. It incorporated fully programmable pixel and vertex shaders.

About a year later, the architecture was revised to allow for higher frequencies, more efficient memory access, and several other improvements in the R350 family. A budget line of RV350 products was based on this refreshed design with some elements disabled or removed.

Models using the new PCI Express interface were introduced in 2004. Using 110-nm and 130-nm manufacturing technologies under the X300 and X600 names, respectively, the RV370 and RV380 graphics processors were used extensively by consumer PC manufacturers.

R420

[edit]

While heavily based upon the previous generation, this line included extensions to the Shader Model 2 feature-set. Shader Model 2b, the specification ATI and Microsoft defined with this generation, offered somewhat more shader program flexibility.

R520

[edit]

ATI's DirectX 9.0c series of graphics cards, with complete shader Model 3.0 support. Launched in October 2005, this series brought a number of enhancements including the floating point render target technology necessary for HDR rendering with anti-aliasing.

TeraScale-family

[edit]
Main article: TeraScale (microarchitecture)

R600

[edit]
Main articles: Radeon HD 2000 series and Radeon HD 3000 series

ATI's first series of GPUs to replace the old fixed-pipeline and implement unified shader model. Subsequent revisions tuned the design for higher performance and energy efficiency, resulting in the ATI Mobility Radeon HD series for mobile computers.

R700

[edit]
Main article: Radeon HD 4000 series

Based on the R600 architecture. Mostly a bolstered with many more stream processors, with improvements to power consumption and GDDR5 support for the high-end RV770 and RV740(HD4770) chips. It arrived in late June 2008. The HD 4850 and HD 4870 have 800 stream processors and GDDR3 and GDDR5 memory, respectively. The 4890 was a refresh of 4870 with the same amount of stream processors yet higher clock rates due to refinements. The 4870x2 has 1600 stream processors and GDDR5 memory on an effective 512-bit memory bus with 230.4 Gbit/s video memory bandwidth available.

Evergreen

[edit]
Main article: Radeon HD 5000 series

The series was launched on 23 September 2009. It featured a 40 nm fabrication process for the entire product line (only the HD4770 (RV740) was built on this process previously), with more stream cores and compatibility with the next major version of the DirectX API, DirectX 11, which launched on 22 October 2009 along with Microsoft Windows 7. The Rxxx/RVxxx codename scheme was scrapped entirely. The initial launch consisted of only the 5870 and 5850 models. ATI released beta drivers that introduced full OpenGL 4.0 support on all variants of this series in March 2010.[6]

Northern Islands

[edit]
Main article: Radeon HD 6000 series
Radeon logo from 2011 to 2013

This is the first series to be marketed solely under the "AMD" brand. It features a 3rd generation 40 nm design, rebalancing the existing architecture with redesigned shaders to give it better performance. It was released first on 22 October 2010, in the form of the 6850 and 6870. 3D output is enabled with HDMI 1.4a and DisplayPort 1.2 outputs.

Graphics Core Next-family

[edit]
Main article: Graphics Core Next
AMD Radeon logo from 26 May 2016[7] – 27 October 2020

Southern Islands

[edit]
Main article: Radeon HD 7000 series

"Southern Islands" was the first series to feature the new compute microarchitecture known as "Graphics Core Next"(GCN). GCN was used among the higher end cards, while the VLIW5 architecture utilized in the previous generation was used in the lower end, OEM products. However, the Radeon HD 7790 uses GCN 2, and was the first product in the series to be released by AMD on 9 January 2012.

Sea Islands

[edit]
Main article: Radeon HD 8000 series

The "Sea Islands" were OEM rebadges of the 7000 series, with only three products, code named Oland, available for general retail. The series, just like the "Southern Islands", used a mixture of VLIW5 models and GCN models for its desktop products.

Volcanic Islands

[edit]
Main article: Radeon 200 series

"Volcanic Islands" GPUs were introduced with the AMD Radeon RX 200 series, and were first released in late 2013.[8] The Radeon RX 200 line is mainly based on AMD's GCN architecture, with the lower end, OEM cards still using VLIW5. The majority of desktop products use GCN 1, while the R9 290x/290 & R7 260X/260 use GCN 2, and with only the R9 285 using the new GCN 3.[9]

Caribbean Islands

[edit]
Main article: Radeon 300 series

GPUs codenamed "Caribbean Islands"[10] were introduced with the AMD Radeon RX 300 series, released in 2015. This series was the first to solely use GCN based models, ranging from GCN 1st to GCN 3rd Gen, including the GCN 3-based Fiji-architecture models named Fury X, Fury, Nano and the Radeon Pro Duo.

Arctic Islands

[edit]
Main articles: Radeon 400 series and Radeon 500 series

GPUs codenamed "Arctic Islands" were first introduced with the Radeon RX 400 series in June 2016 with the announcement of the RX 480.[11] These cards were the first to use the new Polaris chips which implements GCN 4th Gen on the 14 nm fab process. The RX 500 series released in April 2017 also uses Polaris chips.[12]

Vega

[edit]
Main article: RDNA (microarchitecture)

RDNA 1

[edit]
Main article: Radeon RX 5000 series

On 27 May 2019, at COMPUTEX 2019, AMD announced the new 'RDNA' graphics micro-architecture,[13] which succeeded the Graphics Core Next micro-architecture. This is the basis for the Radeon RX 5700-series graphics cards, the first to be built under the codename 'Navi'. These cards feature GDDR6 SGRAM and support for PCI Express 4.0.

RDNA 2

[edit]
Main article: Radeon RX 6000 series

On 5 March 2020, AMD publicly announced its plan to release a "refresh" of the RDNA micro-architecture.[14] Dubbed as the RDNA 2 architecture, it was stated to succeed the first-gen RDNA micro-architecture and was initially scheduled for a release in Q4 2020. RDNA 2 was confirmed as the graphics microarchitecture featured in the Xbox Series X and Series S consoles[15] from Microsoft, and PlayStation 5[16] from Sony, with proprietary tweaks and different GPU configurations in each systems' implementation.

AMD unveiled the Radeon RX 6000 series, its next-gen RDNA 2 graphics cards at an online event on 28 October 2020.[17][18] The lineup consists of the RX 6800, RX 6800 XT and RX 6900 XT.[19][20] The RX 6800 and 6800 XT launched on 18 November 2020, with the RX 6900 XT being released on 8 December 2020.[21] Further variants including a Radeon RX 6700 (XT) series based on Navi 22, launched on 18 March 2021, a Radeon RX 6600(XT) series based on Navi 23, launched on 11 August 2021 (that is the 6600XT release date, the RX 6600 launched on 13 October 2021), and a Radeon RX 6500(XT), launched on 19 January 2022.[22][23][24][25][26]

RDNA 3

[edit]
Main article: Radeon RX 7000 series

On 3 November 2022, AMD announced the full details for the RDNA 3 micro-architecture along with the RX 7900 XT and RX 7900 XTX at an event in Las Vegas.[27]

RDNA 4

[edit]
Main article: Radeon RX 9000 series

On 28 February 2025, AMD announced the RDNA 4 micro-architecture along with the RX 9070 and the RX 9070 XT at an online event.[28] On 21 May 2025, AMD announced the RX 9060 XT during its Computex keynote.[29]

Graphics device drivers

[edit]

AMD's proprietary graphics "Radeon Software" (Formerly Catalyst)

[edit]
Main article: AMD Radeon Software

On 24 November 2015, AMD released a new version of their graphics driver following the formation of the Radeon Technologies Group (RTG) to provide extensive software support for their graphics cards. This driver, labelled Radeon Software Crimson Edition, overhauls the UI with Qt, resulting in better responsiveness from a design and system perspective. It includes a new interface featuring a game manager, clocking tools, and sections for different technologies.[55]

Unofficial modifications such as Omega drivers and DNA drivers were available. These drivers typically consist of mixtures of various driver file versions with some registry variables altered and are advertised as offering superior performance or image quality. They are, of course, unsupported, and as such, are not guaranteed to function correctly. Some of them also provide modified system files for hardware enthusiasts to run specific graphics cards outside of their specifications.[citation needed]

On operating systems

[edit]
AMD Catalyst was based on a proprietary binary blob.
The unified kernel-mode driver (DRM/KMS) is utilized by Catalyst and by Mesa 3D.[56] amdkfd was mainlined into Linux kernel 3.19.[57]

Radeon Software is being developed for Microsoft Windows and Linux. As of January 2019, other operating systems are not officially supported. This may be different for the Radeon Pro brand, which is based on identical hardware but features OpenGL-certified graphics device drivers.

ATI previously offered driver updates for their retail and integrated Macintosh video cards and chipsets. ATI stopped support for Mac OS 9 after the Radeon R200 cards, making the last officially supported card the Radeon 9250. The Radeon R100 cards up to the Radeon 7200 can still be used with even older classic Mac OS versions such as System 7, although not all features are taken advantage of by the older operating system.[58]

Ever since ATI's acquisition by AMD, ATI no longer supplies or supports drivers for classic Mac OS nor macOS. macOS drivers can be downloaded from Apple's support website, while classic Mac OS drivers can be obtained from 3rd party websites that host the older drivers for users to download. ATI used to provide a preference panel for use in macOS called ATI Displays which can be used both with retail and OEM versions of its cards. Though it gives more control over advanced features of the graphics chipset, ATI Displays has limited functionality compared to Catalyst for Windows or Linux.

So GCN 3rd Gen. or higher is here full usable for OpenCL 1.2 software.

Supported features

[edit]

The free and open-source driver supports many of the features available in Radeon-branded cards and APUs, such as multi-monitor or hybrid graphics.

Linux

[edit]

The free and open-source drivers are primarily developed on Linux and for Linux.

Other operating systems

[edit]

Being entirely free and open-source software, the free and open-source drivers can be ported to any existing operating system. Whether they have been, and to what extent depends entirely on the man-power available. Available support shall be referenced here.

FreeBSD adopted DRI, and since Mesa 3D is not programmed for Linux, it should have identical support.[citation needed]

MorphOS supports 2D and 3D acceleration for Radeon R100, R200 and R300 chipsets.[61]

AmigaOS 4 supports Radeon R100, R200, R300,[62] R520 (X1000 series), R700 (HD 4000 series), HD 5000 (Evergreen) series, HD 6000 (Northern Islands) series and HD 7000 (Southern Islands) series.[63] The RadeonHD AmigaOS 4 driver has been developed by Hans de Ruiter[64] funded and owned by A-EON Technology Ltd. The older R100 and R200 "ATIRadeon" driver for AmigaOS, originally developed Forefront Technologies has been acquired by A-EON Technology Ltd in 2015.[citation needed]

In the past ATI provided hardware and technical documentation to the Haiku Project to produce drivers with full 2D and video in/out support on older Radeon chipsets (up to R500) for Haiku. A new Radeon HD driver was developed with the unofficial and indirect guidance of AMD open source engineers and currently exists in recent Haiku versions. The new Radeon HD driver supports native mode setting on R600 through Southern Islands GPU's.[65]

GPU Architectures and Generations

Pre-TeraScale architectures (R100 to R500)

The Pre-TeraScale architectures, spanning the to R500 series, represented ' foundational GPU designs, emphasizing fixed-function rendering with distinct vertex and pixel processing stages rather than unified shaders. These generations evolved from basic 3D acceleration to advanced 9 compliance, incorporating programmable elements while retaining a rigid pipeline structure that separated transformation, rasterization, and fragment processing. Fabricated on progressively smaller process nodes from 180 nm to 90 nm, they prioritized fill rate improvements, enhancements, and capabilities, though later models like the R500 faced notable power consumption challenges due to high transistor counts and clock speeds. The R100/RV100/RV200 series, introduced between 2000 and 2002, debuted the Radeon lineup with models such as the Radeon 7200, 7500, and 8500, built on 180 nm and 150 nm processes. These GPUs featured a fixed-function pixel pipeline with up to 4 parallel rendering units, a single programmable vertex engine supporting 7.0 vertex shaders (up to 128 instructions), and 6 units for multi-texturing effects. The architecture included hardware support for bilinear filtering and basic , enabling competitive performance in era-specific titles like , where the Radeon 8500 matched or exceeded NVIDIA's GeForce2 in fill rate tests at resolutions up to 1024x768. Key innovations included integrated 2D/3D acceleration and early up to 2x, though limited floating-point precision in shaders constrained advanced effects. The R200/RV250/RV280 series (2001-2003) enhanced fill rates and with models like the Radeon 9000, 9100, 9200, and 8500 LE, using 150 nm processes. The core featured 4 pixel pipelines, introduced Pixel 1.4 support with 12 arithmetic logic units and 16 texture units, and improved vertex processing for 8.1 compliance, allowing up to 12 texture stages per pass. advanced to 4x ordered grid , boosting image quality in games like without severe performance penalties. Memory bandwidth increased via support up to 128-bit buses, yielding theoretical fill rates up to 1 Gpixel/s in high-end variants like the Radeon 8500, positioning it as a mid-range leader. However, the fixed-function nature limited flexibility compared to emerging programmable paradigms. The R300/R350/RV370 series (2003-2005) marked a leap to full 9.0 support with the Radeon 9500, 9600, and 9800 models on 150 nm and 130 nm nodes, featuring 8 parallel pipelines and 4 vertex shader units compliant with Shader Model 2.0 (up to 256 instructions with flow control). processing advanced to floating-point (s23e8 format) operations across 16 texture and 8 arithmetic units per quad, enabling and complex effects like per- lighting in titles such as Doom 3. The architecture's hierarchical Z-buffer and lossless compression improved efficiency, delivering up to double the frame rates of the R200 series in shader-intensive benchmarks at 1600x1200 resolution. Smoothvision anti-aliasing combined multisampling with for superior edge quality, while TruForm 2.0 enhanced geometry detail adaptively. The R420/R481/R480 series (2004-2005), powering the Radeon X800 lineup on a , refined the R300 design with 16 pixel pipelines, 6-8 vertex units, and 256-bit GDDR-3 memory interfaces for bandwidth exceeding 50 GB/s. These high-end variants supported Shader Model 2.0b with enhanced branching and 512MB frame buffers, improving to 12x modes and to 16x. The architecture emphasized memory efficiency through ring-bus controllers, reducing latency in texture-heavy scenes, and achieved peak fill rates of 8 Gpixels/s in the X800 XT, outperforming NVIDIA's 6800 in 9 workloads by 20-30% in representative tests like 3DMark05. Power draw rose to 100W+, highlighting thermal limitations of the fixed pipeline. The R520 series (2005-2006), the final Pre-TeraScale iteration with models like the Radeon X1800 and X1900 on 90 nm, integrated 16 pipelines, 16 texture units, and 16 ROPs with an "Ultra Threaded Dispatch Processor" managing up to 512 concurrent shader threads for better utilization. It retained separate Shader Model 3.0 vertex (1024 instructions) and pixel units (FP32 precision, dynamic branching) but added Avivo for hardware H.264 decoding and dual 10-bit display outputs, enhancing HD video playback. The 256-bit ring bus and 3-level Z-compression boosted effective bandwidth to 512 GB/s peak, while 3Dc+ normal mapping compressed textures 4:1 for improved performance in games like Half-Life 2 at 2560x1600. Despite these advances, the design's 321 million transistors and 150W+ TDP exacerbated power and heat issues, paving the way for more efficient unified architectures.

TeraScale architectures (R600 to RV790)

The TeraScale architectures (R600 to RV790) marked AMD's transition to unified designs, enabling a single programmable core to handle vertex, , and compute workloads for greater flexibility and efficiency compared to prior fixed-function approaches. Introduced in 2007, this family emphasized innovations like unified processors grouped into SIMD arrays with VLIW execution, dedicated hardware for subdividing polygons to boost geometric detail, and integrated units. Performance evolved significantly across sub-generations, with single-precision floating-point throughput scaling from approximately 0.48 TFLOPS in initial models to over 2.7 TFLOPS in later ones, reflecting process shrinks and architectural tweaks while addressing early power and heat concerns. The R600 and RV670 series, launched in , pioneered TeraScale 1 with 80 unified processors organized into 16 groups, each employing VLIW5 units for parallel execution of up to five operations per cycle. The Radeon HD 2900 XT flagship delivered 475.5 GFLOPS through its 320 stream processors at 743 MHz, alongside a dedicated tessellator capable of up to 15 times more vertices than software-based alternatives. However, the 80 nm process contributed to substantial power demands, with a 215 W TDP that strained cooling solutions and system PSUs, often requiring 550 W or higher supplies. Building on this in 2008, the R700 series refined TeraScale 2 with a 55 nm process, denser integration (up to 956 million in RV770), and the debut of the (UVD) for full hardware decoding of H.264 and formats, offloading CPU resources for smoother HD playback. The Radeon HD 4870, featuring 800 unified shaders across 10 SIMD engines, achieved 1.2 TFLOPS at 750 MHz core clock while reducing power to 160 W TDP, enabling quieter operation and broader compatibility in mid-range builds. The Evergreen lineup (2009-2010) further optimized TeraScale 2 on a 40 nm , incorporating partial 11 compatibility via feature level 10.1 support for enhanced shaders and , alongside Eyefinity for multi-monitor setups. Refinements included wider memory buses (up to 256-bit GDDR5) and improved branch execution in shaders for better IPC. The Radeon HD 5870, powered by the 1600-shader GPU, reached 2.72 TFLOPS with UVD 2.0 enhancements for and advanced profiles, at a 188 W TDP that balanced performance gains with moderate efficiency. Northern Islands (2010-2011) brought TeraScale 3, shifting from VLIW5 to VLIW4 execution units to reduce scheduling complexity and improve utilization for irregular compute workloads, yielding about 10% better density per area without sacrificing peak throughput. This iteration powered select Radeon HD 6000 and 7000 series models on 40 nm, with dual raster engines and advanced texture caching. The Radeon HD 6970, using the 1536-shader Cayman GPU at 880 MHz, delivered 2.7 TFLOPS and 176 GB/s bandwidth via 2 GB GDDR5, at 250 W TDP, positioning it as a high-end contender before the shift to GCN.

Graphics Core Next (GCN) architectures

The (GCN) architecture marked a significant evolution in AMD's GPU design, introduced with the Radeon HD 7000 series to transition from TeraScale architectures and unify graphics rendering and general-purpose computing workloads through a scalable array of compute units (CUs). Introduced to support emerging standards like 12 and 1.2, GCN shifted from the VLIW-based TeraScale approach to a more flexible SIMD/SIMT model, enabling better efficiency in environments. This unification allowed GPUs to handle both pixel and compute shaders seamlessly, paving the way for advanced features like asynchronous compute queues in later iterations. The Southern Islands family, launched in 2011-2012 on a 28 nm process, represented GCN 1.0 and debuted the CU as the core processing element, with each CU containing four SIMD units capable of executing 16 work-items in parallel. Models in the , such as the flagship HD 7970 based on the GPU, featured 32 CUs, a 365 mm² die size, 4.3 billion transistors, and 3 GB GDDR5 , delivering up to 3.79 TFLOPS of single-precision performance at a 925 MHz core clock. This generation emphasized compute unification, supporting 3.0 and providing foundational hardware for and DirectCompute. Building on this, the family (2013-2014) introduced GCN 1.1 and 1.2 variants with enhancements in power efficiency and compute capabilities, including better support for and pointer-based atomics to align with (HSA) initiatives. The Radeon R9 200 and 300 series utilized these, with examples like the R9 290X ( GPU, GCN 1.1) boasting 28 CUs, a 438 mm² die, 6.2 billion transistors, and 4 GB GDDR5, achieving improved thermal performance over GCN 1.0 at similar clock speeds around 1 GHz. These iterations refined resource scheduling for mixed workloads, reducing latency in compute tasks while maintaining compatibility with 11.1.

These cores deliver up to 1.5x the ray-tracing throughput of software-based implementations in RDNA 1, facilitating realistic lighting and shadows in games like at playable frame rates. Building on this, and later architectures enhance ray-tracing efficiency with second- and third-generation cores, achieving over 2x performance per core in RDNA 4. For AI workloads, introduces matrix cores—adapted from CDNA architectures—optimized for wavefront matrix multiply-accumulate (WMMA) operations in low-precision formats like FP16, accelerating inference and upscaling tasks by up to 8x compared to general-purpose shaders. Power management features like ZeroCore Power, first implemented in the , dynamically shut down idle GPUs in multi-GPU configurations, eliminating unnecessary power draw, heat, and noise during low-load states. Across architectures, adjustable voltage and via PowerTune technology allows fine-grained control, balancing performance and efficiency by dynamically adjusting clock speeds based on workload demands—resulting in up to 50% better in compared to RDNA 2. These mechanisms ensure Radeon GPUs maintain competitive efficiency in both discrete and integrated setups. In terms of aggregate performance trends, Radeon rasterization capabilities have scaled dramatically, with theoretical FP32 TFLOPS evolving from around 1-3 TFLOPS in early GCN-era cards (e.g., Radeon HD 7970 at 3.8 TFLOPS) to over 50 TFLOPS in modern flagships like the RX 7900 XTX at 61 TFLOPS. This progression reflects architectural refinements in compute unit density and clock speeds, delivering real-world rasterization uplifts of 50-100% per generation in 4K gaming benchmarks, while maintaining .
