Intel HD Graphics (Sandy Bridge) is an integrated, GT1 graphics controller in the Pentium and Celeron series of processors from Intel’s Sandy Bridge generation. It was announced in mid Q2 of 2011.
HD Graphics (Sandy Bridge) has 6 shader cores, known as ‘unified units’. They support DirectX 10.1, Pixel Shader 4.1 and DirectCompute 4.1. In addition to having access to system memory, the controller can also use the processor’s third level cache, which dramatically increases its performance.
Base frequency of the HD Graphics (Sandy Bridge) is the same for all unified cores, varying with the power of the CPU in which it is integrated. Starting off at 350MHz in low-voltage processors, it can go up to 650MHz. When the need arises, TurboBoost can increase the clock speed can up to 1100MHz (depending on the CPU), resulting in better graphics performance.
HD Graphics (Sandy Bridge) supports displays with a max resolution of 2560×1600. 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 G1 controllers are a musthave for the netbook class of portables.
