The Intel Graphics Media Accelerator, intel Graphics Media Accelerator Driver For Mobile GMA, is a series of integrated graphics processors introduced in 2004 by Intel, replacing the earlier Intel Extreme Graphics series and being succeeded by the Intel HD and Iris Graphics series. This series targets the market of low-cost graphics solutions.
The products in this series are integrated onto the motherboard, have limited graphics processing power, and use the computer’s main memory for storage instead of a dedicated video memory. They are commonly found on netbooks, low-priced laptops and desktop computers, as well as business computers which do not need high levels of graphics capability. PC motherboards sold had an integrated GPU.

Unsourced material may be challenged and removed. The GMA line of GPUs replaces the earlier Intel Extreme Graphics, and the Intel740 line, the latter of which was a discrete unit in the form of AGP and PCI cards with technology that evolved from companies Real3D and Lockheed Martin.
Later, Intel integrated the i740 core into the Intel 810 chipset. The original architecture of GMA systems supported only a few functions in hardware, and relied on the host CPU to handle at least some of the graphics pipeline, further decreasing performance. 2006, many of the functions are now built into the hardware, providing an increase in performance. The 4th generation of GMA combines fixed function capabilities with a threaded array of programmable executions units, providing advantages to both graphics and video performance.
Many of the advantages of the new GMA architecture come from the ability to flexibly switch as needed between executing graphics-related tasks or video-related tasks. S3 ViRGE, the latest GMA generation should ease many of those concerns for the casual gamer. PowerVR technology Intel licensed from Imagination Technologies. Intel used the low-power PowerVR MBX designs in chipsets supporting their XScale platform, and since the sale of XScale in 2006 has licensed the PowerVR SGX and used it in the GMA 500 IGP for use with their Atom platform.
With the introduction of the Platform Controller Hub, the Graphics Media Accelerator series ceased, and the CPU-based Intel HD and Iris Graphics series was created. The GMA 900 was the first graphics core produced under Intel’s Graphics Media Accelerator product name, and was incorporated in the Intel 910G, 915G, and 915Gx chipsets.
The 3D architecture of the GMA 900 was a significant upgrade from the previous Extreme 3D graphics processors. It is a 4 pixel per clock cycle design supporting DirectX 9 pixel shader model 2.
It operates at a clock rate ranging from 160 to 333 MHz, depending on the particular chipset. At 333 MHz, it has a peak pixel fill-rate of 1332 megapixels per second. However, the architecture still lacks support for hardware transform and lighting and the similar vertex shader technologies. The processor uses different separate clock generators for display and render cores.
DVO ports, and two display controllers. 112 MHz LVDS transmitters are included.
The GMA 950 was the second graphics core produced under Intel’s Graphics Media Accelerator product name, and was incorporated in the Intel 945G chipsets. The processor includes an up to 400 MHz 256-bit core, supporting up to 10. DDR2-667 system RAM, up to 224 MB max.
TV-Out via ADD2 cards or media expansion cards. 3D-wise, GMA 950 supports up to four pixels per clock rendering, Microsoft DirectX 9.
4 with ARB extensions on Windows. Integrated graphics found on Q33, Q35, G31 and G33 chipsets. It supports Pixel Shader 2. 4, but Hardware Vertex Shader isn’t supported.
