Intel HD Graphics (Haswell) is an integrated, GT1 graphics controller in the Pentium and Celeron series of processors from Intel’s Haswell generation. It was announced in early Q4 of 2012.
HD Graphics (Haswell) has 10 shader cores, known as ‘unified units’, 2 texture cores and 2 raster cores. They support DirectX 11.1, Pixel Shader 5.0, OpenCL 1.2, OpenGL 4.0, a Quick Sync encoder and a similar 4K video decoder (the latter being disabled in some low-end processors). In addition to having access to system memory, the controller has access to the processor’s third level cache, which dramatically increases its performance.
Base frequency of the HD Graphics (Haswell) is the same for all unified cores, varying with the power of the CPU in which it is integrated. Starting off at 200MHz in low-voltage processors, it can go up to 400MHz. When the need arises, the clock speed can be increased up to 1000MHz (depending on the CPU), resulting in better graphics performance.
HD Graphics (Haswell) supports up to three individual displays with a max resolution of 4096×4086. Power consumption is lower when compared to NVIDIA and AMD’s discreet solutions. There is also significantly less heat, since the controller is part of the CPU package. For this reason, integrated GT1 controllers are a must-have for the netbook class of portables.
