[[File:AMD Radeon HD7870 Die and Package.jpg|thumb|The die and package of a Radeon HD 7870 graphics card.]]

The 28&nbsp;nm product line is divided in three dies (''Tahiti'', ''Pitcairn'', and ''Cape Verde''), each one roughly double in shader units compared to its small brethren (32, 20, and respectively 10 GCN compute units). While this gives roughly a doubling of 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.<ref name="be">{{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 |accessdate= August 22, 2013}}</ref> 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|tessellation]] benchmarks.<ref name="be"/>

===Radeon HD 7900===
Codenamed ''Tahiti'', the Radeon HD 7900 series was announced on December 22, 2011.

== Graphics device drivers ==
=== AMD's proprietary graphics device driver "Catalyst" ===
AMD Catalyst is being developed for [[Software:Microsoft Windows|Microsoft Windows]] and [[Software:Linux|Linux]]. As of July 2014, other operating systems are not officially supported. This may be different for the [[Engineering:AMD FirePro|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.

=== Free and open-source graphics device driver "Radeon" ===

The free and open-source drivers are primarily developed on [[Software:Linux|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 [[Software:Direct Rendering Manager|DRM]]
# Linux kernel component [[Software:KMS driver|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 [[Software:X.Org Server|X.Org Server]], which if finally about to be replaced by [[Software:X.Org Server#Glamor|Glamor]]

The free and open-source "Radeon" graphics driver supports most of the features implemented into the Radeon line of GPUs.<ref name="radeonfeature"/>

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