memory. 3 The TDP is reference design TDP values from AMD. Different non-reference board designs from vendors may lead to slight variations in actual TDP. 4 All models feature UVD2 and PowerPlay. IGP (HD 4000) All Radeon HD 4000 IGP models include Direct3D 10.1 and OpenGL 2.0 1 Unified shaders : Texture mapping units : Render output units 2 The clock frequencies may vary in different usage scenarios, as ATI PowerPlay technology is implemented. The clock frequencies listed here refer to the officially announced clock specifications. 3 The sideport is a dedicated memory bus. It preferably used for frame buffer. Radeon HD 5000 series The HD5000 series is the last series of AMD GPUs which supports two analog CRT-monitors with a single graphics card (i.e. with two RAM-DACs). AMD Eyefinity introduced. Radeon HD 6000 series • The Radeon HD 6000 series has a new tesselation engine which is said to double the performance when working with tesselation compared to the previous HD 5000 series. IGP (HD 6000) All models feature the UNB/MC Bus interface All models do not feature double-precision FP With driver Update OpenGL 4.4 available (Last Catalyst 15.12). OpenGL 4.5 available with Crimson Beta (driver version 15.30 or higher). All models feature Angle independent anisotropic filtering, UVD3, and AMD Eyefinity capabilities, with up to three outputs. All models feature 3D Blu-ray Disc acceleration. Embedded GPU's as part of AMD's Lynx platform APU's. Radeon HD 7000 series IGP (HD 7000) All models feature the UNB/MC Bus interface All models do not support double-precision FP TeraScale 2 (VLIW5) based APUs feature angle independent anisotropic filtering, UVD3, and Eyefinity capabilities, with up to three outputs. TeraScale 3 (VLIW4) based APUs feature angle independent anisotropic filtering, UVD3.2, and Eyefinity capabilities, with up to four outputs.
