Radeon HD 8000 series

Family of GPUs by AMD From Wikipedia, the free encyclopedia

Radeon HD 8000 series
Remove ads

The Radeon HD 8000 series is a family of computer GPUs developed by AMD. AMD was initially rumored to release the family in the second quarter of 2013,[9][10][11] with the cards manufactured on a 28 nm process and making use of the improved Graphics Core Next architecture.[12] However the 8000 series turned out to be an OEM rebadge of the 7000 series (although Bonaire is a GCN 2.0 based chip, thus being of newer development).

Architecture

Summarize
Perspective

The Radeon HD 7000 series was launched in 2011 and it marked AMD's shift from VLIW (TeraScale) to RISC/SIMD architecture (Graphics Core Next). The highend-mainstream cards were equipped with GCN-based chips while some of the mid-low end ones were just rebranded TeraScale-based cards. All of the GCN-based chips were made using the 28 nm process, becoming the first chips ever to be based on that technology. The GCN-based chips for desktop cards were codenamed as Southern Islands, while the mobile ones (again, only the GCN-based and not the rebranded ones) were codenamed as Solar System.

Multi-monitor support

The AMD Eyefinity-branded on-die display controllers were introduced in September 2009 alongside the Radeon HD 5000 series and have been present on all chips since then.[13]

Video acceleration

Both Unified Video Decoder (UVD) and Video Coding Engine (VCE) are present on all GCN-based chips (starting with the GCN 1.0 HD 7000 series). Both are fully supported by AMD Catalyst and by the free and open-source graphics device driver#ATI/AMD.

OpenCL (API)

OpenCL accelerates many scientific Software Packages against CPU up to factor 10 or 100 and more. OpenCL 1.0 to 1.2 are supported for all Chips with TeraScale and GCN Architecture. OpenCL 2.0 is supported with GCN 2nd Gen. or 1.2 and higher) [14] For OpenCL 2.1 and 2.2 only Driver Updates are necessary with OpenCL 2.0 conformant Cards.

Vulkan (API)

API Vulkan 1.0 is supported for all with GCN Architecture. Vulkan 1.1 (GCN 2nd Gen. or 1.2 and higher) will be supported with actual drivers in 2018 (here only HD 8770).[14][needs update] On newer drivers Vulkan 1.1 on Windows and Linux is supported on all GCN-architecture based GPUs. Vulkan 1.2 is available with Adrenalin 20.1 and Linux Mesa 20.0 for GCN 2nd Gen. or higher.

  1. Boost values (if available) are stated below the base value in italic.
  2. Texture fillrate is calculated as the number of Texture Mapping Units multiplied by the base (or boost) core clock speed.
  3. Pixel fillrate is calculated as the number of Render Output Units multiplied by the base (or boost) core clock speed.
  4. Precision performance is calculated from the base (or boost) core clock speed based on a FMA operation.
  5. The effective data transfer rate of GDDR5 is quadruple its nominal clock, instead of double as with DDR memory.
  6. Lacks hardware video encoder

The following table shows features of AMD/ATI's GPUs (see also: List of AMD graphics processing units).

  1. 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.
  2. 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.
  3. OpenGL 4+ compliance requires supporting FP64 shaders and these are emulated on some TeraScale chips using 32-bit hardware.
  4. Vulkan support is theoretically possible but has not been implemented in a stable driver.
  5. The UVD and VCE were replaced by the Video Core Next (VCN) ASIC in the Raven Ridge APU implementation of Vega.
  6. 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.
  7. 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.
  8. More displays may be supported with native DisplayPort connections, or splitting the maximum resolution between multiple monitors with active converters.
  9. 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.
