The graphics card is only overclocked if the CPU is not fully loaded and the TDP is not fully used. The Turbo Boost function of the new Arrandale CPUs also allows the automatic overclocking of the GPU core.

The same was noticed with WMV videos (The Magic of Flight 1080p 3-5% versus 7-12%) and VC-1 videos (Elephant's Dream 1080p 5-8% versus 8-15%). When using the VLC which did not support using the graphic card, the CPU load was significantly higher with 8-17% in our tests.

A Toshiba Tecra A11 laptop with Core i5-430M CPU decoded Big Buck Bunny (1080p, H.264) using the Windows Media Player using the graphics card with only 0-1% CPU load. The DXVA Checker lists support for MPEG2 (VLD, IDCT, MoComp, A, C), H264 (VLD, MoComp, IDCT), WMV9 (MoComp, IDCT), and VC1 (MoComp, IDCT) in 72x480, 1280x720 and 1920x1080. Similar to the 4500MHD, the GMA HD also offers hardware accelerated HD video functions in the chip. the old Doom 3 and Quake 4 games wont run fluently. Furthermore, Low Voltage and Ultra Low Voltage Core CPUs contain lower clocked GMA HD graphics and are therefore slower.įurthermore, the OpenGL performance is still not very good.

The driver support is still not as good as for Nvidia and AMD graphics cards. On average it should be as fast as the HD 3200 / 4200 by ATI and therefore allow the user to play older and less demanding games in low settings. In some games, the GMA HD is even as fast as a GeForce 9400M / ION chipset. The performance of the new Graphics Media Accelerator HD graphics card is noticable better than the old GMA 4500MHD (due to the increased number of shaders and in some cases also clock rate). The identically called Intel HD Graphics in entry level Sandy Bridge processors is the successor of this graphics card and offers an improved architecture and therefore faster speeds. 500-766 MHz). Compared, the the CPU die, the GPU and memory controller are produced in 45nm and not 32nm.Ĭompared to the current GMA 4500MHD graphics adapter, the Graphics Media Accelerator HD got two more shaders leading in 12 execution units (or unified shader cores).
Depending on the CPU model, the GMA HD is clocked between 166 and 500 MHz (with Turbo Boost max.
The Intel Graphics Media Accelerator HD Graphics, Intel HD Graphics, or GMA HD (or GMA5700MHD) is an onboard / shared memory graphics card for laptops that is bundled in the package of the new Arrandale dual core CPUs (upcoming in Q1 2010). Intel Graphics Media Accelerator (GMA) HD Graphics
