Radeon HD 7000 series#Radeon HD 7900

Graphics Core Next was introduced with the Radeon HD 7000 series.

• A GPU implementing Graphics Core Next is found on the Radeon HD 7730 and above branded discrete GPUs.
• A GPU implementing TeraScale (microarchitecture) version "Evergreen (VLIW5)" is found on Radeon HD 7670 and below branded discrete GPUs.
• A GPU implementing TeraScale (microarchitecture) version "Northern Islands (VLIW4)" is found on APUs whose GPUs are branded with the Radeon HD 7000 series.
• OpenGL 4.x compliance requires supporting FP64 shaders. These are implemented by emulation on some TeraScale (microarchitecture) GPUs.
• On Windows, Vulkan 1.0 requires GCN-Architecture. Vulkan 1.1 requires actual 2nd Gen. of GCN or higher (here only HD 7790).{{cite web|url=https://www.khronos.org/conformance/adopters/conformant-products#submission_318|title = Conformant Products (submission 318)|publisher = The Khronos Group Inc|author = Advanced Micro Devices, Inc.|date = 22 April 2018}} On newer AMD drivers Vulkan 1.1 on Windows and Linux is supported on all GCN-architecture based GPUs.

{{Main|AMD Eyefinity}}

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.{{cite web |url=http://support.amd.com/en-us/kb-articles/Pages/AMDEyefinityFAQs.aspx |title=AMD Eyefinity: FAQ |work=AMD |date=2011-05-17 |access-date=2014-07-02}}

Both Unified Video Decoder (UVD) and Video Coding Engine (VCE) are present on the dies of all products and supported by AMD Catalyst and by the free and open-source graphics device driver#ATI/AMD.

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.{{cite web | url=https://www.khronos.org/conformance/adopters/conformant-products | title=The Khronos Group | date=15 June 2022 }} For OpenCL 2.1 and 2.2 only Driver Updates are necessary with OpenCL 2.0 conformant Cards.

Vulkan 1.1 is supported for all with GCN Architecture using recent drivers on both Linux and Windows.

Vulkan 1.2 is available for GCN 2nd Gen or higher with Windows Adrenalin 20.1(and newer).

Vulkan 1.3 is available for GCN 1st Gen and higher with Mesa RADV on Linux.

The 28 nm product line is divided in three dies (Tahiti, Pitcairn, and Cape Verde), each one highly increasing shader units (32, 20 and 10 respectively). While this gives a high increase in single-precision floating point, there is however a significant departure in double-precision compute power. Tahiti has a maximum ¼ double precision throughput relative to its single precision throughput, while the other two smaller consumer dies can only achieve a 1/16 ratio.{{cite web |url= http://www.behardware.com/art/imprimer/856/ |title= Review: AMD Radeon HD 7850 & 7870 |language= fr|publisher= BeHardware |date= March 5, 2012 |access-date= August 22, 2013}} While each bigger die has two additional memory controllers widening its bus by 128 bits, Pitcairn however has the same front-end dual tesselator units as Tahiti giving it similar performance to its larger brethren in DX11 tessellation benchmarks.

Codenamed Tahiti, the Radeon HD 7900 series was announced on December 22, 2011. Products include the Radeon 7970 GHz Edition, Radeon HD 7970 and Radeon HD 7950.{{Cite news|url=https://us.hardware.info/reviews/2609/amd-radeon-hd-7000-series-reviewed|title=AMD Radeon HD 7000 series reviewed|work=Hardware.Info|access-date=2017-08-28|language=en-US}} The Radeon HD 7970 features 2048 usable stream cores,{{efn-ua|Corresponding to 32 cores in "the closest reasonable mapping to the equivalent in a CPU".{{cite book |title=Heterogeneous Computing with OpenCL: Revised OpenCL 1.2 Edition |first1=Benedict |last1=Gaster |first2=Lee |last2=Howes |first3=David R. |last3=Kaeli |author-link3=David R.

The cards are the first products to take advantage of AMD's new "Graphics Core Next" compute architecture. Both cards are equipped with 3 GB GDDR5 memory and manufactured on TSMC's 28 nm process. The Tahiti GPU is also used in the Radeon HD 7870 XT, released November 19, 2012. In this case one quarter of the stream processors are disabled, giving 1536 usable cores. Additionally, the memory interface is downgraded from 384-bit to 256-bit, along with a memory size reduction from 3 GB to 2 GB.

Codenamed Pitcairn, the Radeon HD 7800 series was formally unveiled on March 5, 2012, with retail availability from March 19, 2012. Products include the Radeon HD 7870 and Radeon HD 7850. The Radeon HD 7870 features 1280 usable stream cores, whereas the Radeon HD 7850 has 1024 usable stream cores. Both cards are equipped with 2GB GDDR5 memory (some 7850s offer 1GB) and manufactured on TSMC's 28 nm process.{{cite web |url= http://www.anandtech.com/show/5625/amd-radeon-hd-7870-ghz-edition-radeon-hd-7850-review-rounding-out-southern-islands |title= AMD Radeon HD 7870 GHz Edition & Radeon HD 7850 Review: Rounding Out Southern Islands |publisher= AnandTech |access-date= August 22, 2013}}

Codenamed Cape Verde, the Radeon HD 7700 series was released on February 15, 2012. Products include the Radeon HD 7770 GHz Edition and Radeon HD 7750. The Radeon HD 7770 GHz Edition features 640 stream cores based on the GCN architecture, whereas the Radeon HD 7750 has only 512 usable stream cores. Both cards are equipped with 1 GB GDDR5 memory and manufactured in 28 nm. On March 22, 2013, another card, Radeon HD 7790, was introduced in this series. This card is based on the Bonaire architecture, which features 896 stream cores using 2nd Generation GCN technology, an incremental update. In May 2013, AMD launched the Radeon HD 7730, based on the Cape Verde LE graphics processor. It features a 128-bit memory bus, 384 stream cores, 8 ROPs, and a core clock speed of up to 800 MHz. The HD 7730 came with GDDR5 and DDR3 variants, running on memory clock speeds of 1125 MHz and 900 MHz, respectively. Load power usage was lowered by 14.5% (47W) compared to the Radeon HD 7750 (55W).{{cite web|last=Woligroski |first=Don |url=http://www.tomshardware.com/reviews/radeon-hd-7730-cape-verde-review,3575.html |title=AMD Radeon HD 7730 Review: A Harbinger Of The Kaveri APU? | Tom's Hardware |publisher=Tomshardware.com |date= 5 August 2013|accessdate=2022-05-13}}

{{Main|AMD Catalyst}}

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.

{{Main|free and open-source graphics device driver#ATI/AMD|l1=free and open-source "radeon" graphics device driver}}

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.

The free and open-source "Radeon" graphics device drivers are not reverse engineered, but based on documentation released by AMD.{{cite web |url=http://developer.amd.com/resources/documentation-articles/developer-guides-manuals/ |title=AMD Developer Guideds}}
