Three different families of microarchitectures can be roughly distinguished, the fixed-pipeline family, the unified shader model-families of TeraScale and Graphics Core Next. Radeon Graphics is the successor to the Rage line.
It also features an improved decoder for 4K videos and the fast Quick Sync encoder. The GPU now supports DirectX 11.1, OpenCL 1.2 and OpenGL 4.0. In comparison to the HD 4000, the HD 4400 graphics core has been modified extensively. Depending on the processor model, the turbo clock rates may differ, resulting in varying graphics performance between models. The Intel HD Graphics 4400 (GT2) is a processor graphics card included in some of the ULV Haswell processors of 2013. The relatively low base clock can be automatically overclocked using Turbo Boost technology. Intel HD Graphics 4400 ► remove from comparison
