The Radeon R700 is the engineering codename for a graphics processing unit series developed by Advanced Micro Devices under the ATI brand name. The foundation chip, codenamed RV770, was announced and demonstrated on June 16, 2008 as part of the FireStream 9250 and Cinema 2.0 initiative launch media event,[5] with official release of the Radeon HD 4800 series on June 25, 2008. Other variants include enthusiast-oriented RV790, mainstream product RV730, RV740 and entry-level RV710.
Its direct competition was nVidia's GeForce 200 series, which launched in the same month.
Architecture
[edit]This article is about all products under the brand "Radeon HD 4000 Series". All products implement TeraScale 1 microarchitecture.
Execution units
[edit]The RV770 extends the R600's unified shader architecture by increasing the stream processing unit count to 800 units (up from 320 units in the R600), which are grouped into 10 SIMD cores composed of 16 shader cores containing 4 FP MADD/DP ALUs and 1 MADD/transcendental ALU. The RV770 retains the R600's 4 Quad ROP cluster count, however, they are faster and now have dedicated hardware-based AA resolve in addition to the shader-based resolve of the R600 architecture. The RV770 also has 10 texture units, each of which can handle 4 addresses, 16 FP32 samples, and 4 FP32 filtering functions per clock cycle.[6]
Memory and internal buses
[edit]RV770 features a 256-bit memory controller and is the first GPU to support GDDR5 memory, which runs at 900 MHz giving an effective transfer rate of 3.6 GHz and memory bandwidth of up to 115 GB/s. The internal ring bus from the R520 and R600 has been replaced by the combination of a crossbar and an internal hub.[7]
Video acceleration
[edit]The SIP block UVD 2.0-2.2 implemented on the dies of all Radeon HD 4000 Series Desktop gpus, 48xx series is using uvd 2.0, 47xx-46xx-45xx-43xx series is using uvd 2.2.
Support is available for Microsoft Windows at release, for Linux with Catalyst 8.10. The free and open-source driver requires Linux kernel 3.10 in combination with Mesa 9.1 (exposed via the widely adopted VDPAU)[8]), offering full hardware MPEG-2, H.264/MPEG-4 AVC and VC-1 decoding and the support for dual video streams, the Advanced Video Processor (AVP) also saw an upgrade with DVD upscaling capability and dynamic contrast feature. The RV770 series GPU also supports xvYCC color space output and 7.1 surround sound output (LPCM, AC3, DTS) over HDMI. The RV770 GPU also supports an Accelerated Video Transcoding (AVT) feature, which has video transcoding functions being assisted by the GPU, through stream processing.
GPU interconnect enhancements
[edit]
This generation of dual-GPU design retains the use of a PCI Express bridge, PLX PEX 8647 with a power dissipation of 3.8 watts inclusive of PCI Express 2.0 support, allowing two GPUs on the same PCI Express slot with doubled bandwidth over the past generation of product (Radeon HD 3870 X2). Subsequent generations of dual-GPU design also feature an interconnect for inter-GPU communications through the implementation of a CrossFire X SidePort on each GPU, giving extra 5 GB/s full-duplex inter-GPU bandwidth. These two features increase total bandwidth for dual-GPU designs to 21.8 GB/s.
OpenCL (API)
[edit]OpenCL accelerates many scientific Software Packages against CPU up to factor 10 or 100 and more. Open CL 1.0 to 1.1 are supported for all Chips with RV7xx.[9]
Desktop products
[edit]Radeon HD 4800
[edit]The Radeon HD 4850 was announced on June 19, 2008 while the Radeon HD 4870 was announced on June 25, 2008. They are both based on the RV770 GPU, packing 956 million transistors and being produced on a 55 nm process. The Radeon HD 4850 currently uses GDDR3 memory, while the Radeon HD 4870 uses GDDR5 memory.
Another variant, the Radeon HD 4830 was updated on October 23, 2008, featuring the RV770 LE GPU with a 256-bit GDDR3 memory interface, and 640 shader processors. Basically the RV770 LE is a RV770 with some functional units disabled.
Dual GPU products using two RV770 GPUs, codenamed R700, were also announced. One product named Radeon HD 4870 X2, featuring 2×1GB GDDR5 memory, was released on August 12, 2008, while another dual-GPU product, the Radeon HD 4850 X2, with GDDR3 memory and lower clock speeds, is also available.
A minor update was introduced on April 2, 2009 with the launch of Radeon HD 4890 graphics cards based on the RV790 GPU. Featuring an improved design with decoupling capacitors to reduce signal noise,[10] altered ASIC power distribution and re-timed the whole GPU chip, which resulted in a slight increase in die size but overall much better stability at high clock rates and a higher default clock. On August 18, 2009, AMD released a stripped down variant of the RV790 GPU called the RV790GT that is used by the Radeon HD 4860 which is now available in all markets.
Radeon HD 4700
[edit]
The Radeon HD 4700 series was announced on April 28, 2009. The Radeon HD 4770, is based on the RV740 GPU, packs 826 million transistors and being produced on the latest 40 nm process. The Radeon HD 4730 was introduced June 8, 2009, unlike the RV740 based Radeon HD 4770, the 4730 is a stripped down 55 nm RV770 GPU, named the RV770CE. The 4730 packs 956 million transistors, and uses GDDR5 memory on a 128-bit bus. On September 9, 2009, the RV740PRO based Radeon HD 4750 was released exclusively to the Chinese market. The Radeon HD 4750 is based on the 40 nm RV740 of the Radeon HD 4770 but features a lower clock speed and the absence of a six-pin auxiliary power input.
Radeon HD 4600
[edit]The Radeon HD 4600 series was announced on September 10, 2008. All variants are based on the RV730 GPU, packing 514 million transistors and being produced on a 55 nm process. The PCIe version 4600 series products do not require external power connectors.[11][12][13][14] More recently, an AGP version of the 4670 has been released. This does require an external power connector. As of March 2018, this elusive AGP card remains among the last cards using the aging bus.
Radeon HD 4300/HD 4500
[edit]
The Radeon HD 4350 and Radeon HD 4550 were announced on September 30, 2008, both based on the RV710 GPU, packing 242 million transistors and being produced on a 55 nm process. Both products use either GDDR3, DDR3 or DDR2 video memory. AMD states these two products have maximum of 20 W and 25 W of power consumption under full load, respectively.[15]

- ^ The Radeon 100 Series has programmable pixel shaders, but do not fully comply with DirectX 8 or Pixel Shader 1.0. See article on R100's pixel shaders.
- ^ R300, R400 and R500 based cards do not fully comply with OpenGL 2+ as the hardware does not support all types of non-power of two (NPOT) textures.
- ^ OpenGL 4+ compliance requires supporting FP64 shaders and these are emulated on some TeraScale chips using 32-bit hardware.
- ^ a b c The UVD and VCE were replaced by the Video Core Next (VCN) ASIC in the Raven Ridge APU implementation of Vega.
- ^ Video processing for video frame rate interpolation technique. In Windows it works as a DirectShow filter in your player. In Linux, there is no support on the part of drivers and / or community.
- ^ a b To play protected video content, it also requires card, operating system, driver, and application support. A compatible HDCP display is also needed for this. HDCP is mandatory for the output of certain audio formats, placing additional constraints on the multimedia setup.
- ^ More displays may be supported with native DisplayPort connections, or splitting the maximum resolution between multiple monitors with active converters.
- ^ a b DRM (Direct Rendering Manager) is a component of the Linux kernel. AMDgpu is the Linux kernel module. Support in this table refers to the most current version.

[edit]Graphics device drivers
[edit]AMD's proprietary graphics device driver "Catalyst"
[edit]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.
The Radeon HD 4000 series has been transitioned to legacy support, where drivers will be updated only to fix bugs instead of being optimized for new applications.[31]
Free and open-source graphics device driver "Radeon"
[edit]The free and open-source drivers are primarily developed on Linux 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" graphics driver supports most of the features implemented into the Radeon line of GPUs.[32]
The free and open-source "Radeon" graphics device drivers are not reverse engineered, but based on documentation released by AMD.[33]
