The Intel HD Graphics (Bay Trail) is a low-end integrated Bay Trail graphics card found in certain Atom models (Z3770), nettops (J2850) and notebook SoCs (N3510). It supports DirectX 11 and is based on the Ivy Bridge GPU. Clock rates and shader cores, however, are considerably lower.
Compared to Ivy Bridge, which offers either 6 or 16 Execution Units, the HD Graphics (Bay Trail) comes with only 4 EUs. The core clock is significantly lower as well. Depending on the specific model, the maximum Turbo Boost is 896 MHz or less and the memory controller can support DDR3(L), DDR3L-RS or LPDDR3 in single- or dual-channel operation.
The fastest notebook models equipped with this GPU nearly match the performance of the HD Graphics (Sandy Bridge) and the AMD Radeon HD 6310. Therefore, older and less demanding Windows games like World of Warcraft or Half-Life 2 can be played fluently in very low settings. Performance is not sufficient for most modern titles.
Compared to competing ARM SoCs, Bay Trail outperforms the Adreno 320 (which can be found in different Qualcomm SoCs like the Snapdragon 600) and offers a performance similar to the Tegra 4 GPU. That is enough power to run even the most demanding Android games smoothly in very high resolutions as of 2013.
The integrated video decoder supports all popular codecs such as MPEG2, H.264, VC1, VP8 and MVC and is suitable for resolutions up to 4K up to 100 Mbit/s. The user can connect up to two displays via HDMI 1.4 (max. 1920 x 1080) or DisplayPort 1.2 (max. 2560 x 1600). Another new feature is the support for Wireless Display and Quick Sync, Intel's fast and power efficient H-264 hardware encoder. Some of these features are not available on all models.
Depending on the model, the power consumption of the entire SoC is somewhere between 2 and 10 W. The most efficient versions are therefore suitable for passively cooled tablets, whereas faster variants are used in larger subnotebooks with active cooling.
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.
