Intel HD Graphics 3000 is an integrated, GT1 graphics controller in the Core i-series of processors from Intel’s Sandy Bridge generation. It was announced in mid Q1 of 2011 and successfully stands against NVIDIA and AMD’s low-end dedicated memory graphics.
HD Graphics 3000 has 12 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 3000 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 1350MHz (depending on the CPU), resulting in better graphics performance.
HD 3000 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 must-have for the Ultrabook class of portables.
