Intel HD Graphics 2000
The Intel HD Graphics 2000 (or Intel Graphics Media Accelerator HD 2000 or GMA HD 2000) is an integrated graphics card in the Sandy Bridge codenamed processors. It is included in slower mobile processors (Pentium brand e.g. but called only Intel HD Graphics) and in most desktop processors. The HD Graphics 2000 has no dedicated memory but shares the fast Level 3 Cache with the CPU cores and also part of the main memory. Due to Turbo Boost, the GPU can be overclocked depending on the current CPU load and power consumption. The GMA HD 2000 offers only half of the 12 Execution Units (EUs) of the Intel GMA HD 3000.
Because of the halfed amount of shaders, the gaming performance is only compareable to the old Intel GMA HD (in the Arrandale CPUs). Our tests with a desktop i5-2400 showed a performance level of a Geforce G 105M e.g. which is slightly faster. Therefore, only low demanding games like Sims 3 or World of Warcraft can be played in low detail settings fluently.
Altought 2x Antialiasing (AA) is supported, the chip is as fast as when rendering 4x AA. In the Unigine Valley benchmark a similar HD 3000 i7-2637M for example reached the same score with 2x AA and 4x AA.
In addition to the GPU, the chip also houses some dedicated units for decoding and encoding HD videos. On the IDF Intel demonstrated the encoding of a 3 minute long 1080p video to an iPhone compatible format in 640x360 in only 14s. Another novelty of the Sandy Bridge GPU is the embedded DisplayPort eDP to connect internal Displays.
Due to the integration in the 32nm built CPU and the halfed amount of shaders, the power consumption of the GPU should be quite low and also suited for small and light laptops.
