Radeon 200 series

Series of video cards


The Radeon 200 series is a series of graphics processors developed by AMD. These GPUs are manufactured on a 28 nm Gate-Last process through TSMC or Common Platform Alliance.[8]

Quick Facts Release date, Codename ...

Release

The Rx 200 series was announced on September 25, 2013, at the AMD GPU14 Tech Day event.[9] Non-disclosure agreements were lifted on October 15, except for the R9 290X, and pre-orders opened on October 3.[10]

Architecture

  • Graphics Core Next 3 (Volcanic Islands) is found on the R9 285 (Tonga Pro) branded products.
  • Graphics Core Next 2 (Sea Islands) is found on R7 260 (Bonaire), R7 260X (Bonaire XTX), R9 290 (Hawaii Pro), R9 290X (Hawaii XT), and R9 295X2 (Vesuvius) branded products.
  • Graphics Core Next 1 (Southern Islands) is found on R9 270, 270X, 280, 280X, R7 240, 250, 250X, 265, and R5 240 branded products.
  • TeraScale 2 (VLIW5) (Northern Islands or Evergreen) is found on R5 235X and below branded products.
  • OpenGL 4.x compliance requires supporting FP64 shaders. These are implemented by emulation on some TeraScale (microarchitecture) GPUs.
  • Vulkan 1.0 requires GCN-Architecture. Vulkan 1.1 requires GCN 2 or higher.[11]

Multi-monitor support

The AMD Eyefinity-branded on-die display controllers were introduced in September 2009 in the Radeon HD 5000 series and have been present in all products since.[12]

AMD TrueAudio

AMD TrueAudio was introduced with the AMD Radeon Rx 200 series, but can only be found on the dies of GCN 2/3 products.

Video acceleration

AMD's SIP core for video acceleration, Unified Video Decoder and Video Coding Engine, are found on all GPUs and supported by AMD Catalyst and by the free and open-source graphics device driver.

Use in cryptocurrency mining

During 2014 the Radeon R9 200 series GPUs offered a very competitive price for usage in cryptocurrency mining. This led to limited supply and huge price increases of up to 164% over the MSRP in Q4 of 2013 and Q1 of 2014.[13][14] Since Q2 of 2018 availability of AMD GPUs as well as pricing has, in most cases, returned to normal.

CrossFire Compatibility

Because many of the products in the range are rebadged versions of Radeon HD products, they remain compatible with the original versions when used in CrossFire mode. For example, the Radeon HD 7770 and Radeon R7 250X both use the 'Cape Verde XT' chip so have identical specifications and will work in CrossFire mode. This provides a useful upgrade option for anyone who owns an existing Radeon HD card and has a CrossFire compatible motherboard.

Virtual super resolution support

Starting with the driver release candidate version v14.501-141112a-177751E, officially named as Catalyst Omega, AMD's driver release introduced VSR on the R9 285 and R9 290 series graphics cards. This feature allows users to run games with higher image quality by rendering frames at above native resolution. Each frame is then downsampled to native resolution. This process is an alternative to supersampling which is not supported by all games. Virtual super resolution is similar to Dynamic Super Resolution, a feature available on competing nVidia graphics cards, but trades flexibility for increased performance.[15][16] VSR can run at a resolution upwards of 2048 x 1536 at a 120 Hz refresh rate or 3840 x 2400 at 60 Hz.[17]

OpenCL (API)

OpenCL accelerates many scientific Software Packages against CPU up to factor 10 or 100 and more. Open CL 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.[18] 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 GCN architecture cards. Vulkan 1.2 requires GCN 2nd gen or higher with the Adrenalin 20.1 and Linux Mesa 20.0 drivers and newer.

Desktop models

Radeon R9 295X2

The Radeon R9 295X2 was released on April 21, 2014. It is a dual GPU card. Press samples were shipped in a metal case. It is the first reference card to utilize a closed looped liquid cooler.[19][20] At 11.5 teraflops of computing power, the R9 295X2 was the most powerful dual-gpu consumer-oriented card in the world, until it was succeeded by the Radeon Pro Duo on April 26, 2016, which is essentially a combination of two R9 Fury X (Fiji XT) GPUs on a single card.[19] The R9 295x2 has essentially two R9 290x (Hawaii XT) GPUs each with 4GB GDDR5 VRAM.[19]

  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. The UVD and VCE were replaced by the Video Core Next (VCN) ASIC in the Raven Ridge APU implementation of Vega.
  5. 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.
  6. 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.
  7. More displays may be supported with native DisplayPort connections, or splitting the maximum resolution between multiple monitors with active converters.
  8. 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.

Graphics device drivers

AMD's proprietary graphics device driver "Catalyst"

AMD Catalyst is being developed for Microsoft Windows and Linux. As of July 2014, other operating system 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 of course all features advertised for the Radeon brand.

Free and open-source graphics device driver "Radeon"

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:

  1. Linux kernel component DRM
  2. Linux kernel component KMS driver: basically the device driver for the display controller
  3. user-space component libDRM
  4. user-space component in Mesa 3D;
  5. a special and distinct 2D graphics device driver for X.Org Server, which if 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.[5] Unlike the nouveau project for Nvidia graphics cards, the open-source "Radeon" drivers are not reverse engineered, but based on documentation released by AMD.[63]
