Intel GMA
Intel's low-cost integrated graphics series for netbooks and business PCs.
The Intel Graphics Media Accelerator (GMA) is a series of integrated graphics processors introduced in 2004 by Intel, replacing the earlier Intel Extreme Graphics series. It targets the market of low-cost graphics solutions, being integrated onto the motherboard, using the computer's main memory for storage instead of dedicated video memory, and commonly found on netbooks, low-priced laptops and desktop computers, as well as business computers. The series was succeeded by the Intel HD and Iris Graphics series.

Lore & Background
The GMA line replaces the earlier Intel Extreme Graphics and the Intel740 line, the latter of which was a discrete unit with technology from Real3D and Lockheed Martin. The original GMA architecture supported only a few functions in hardware, relying on the host CPU to handle parts of the graphics pipeline, decreasing performance. With the 4th generation (GMA X3000) in 2006, many functions were built into hardware, combining fixed function capabilities with a threaded array of programmable execution units, allowing flexible switching between graphics and video tasks. GMA performance was widely criticized as too slow for computer games, sometimes nicknamed 'GMD' (Graphics Media Decelerator), but the latest generation was said to ease concerns for casual gamers. Despite similarities, Intel's main GMA series is not based on PowerVR technology; Intel used PowerVR MBX designs for XScale and later licensed PowerVR SGX for the GMA 500 on the Atom platform. With the introduction of the Platform Controller Hub, the GMA series ceased and the CPU-based Intel HD and Iris Graphics series was created.
Reader's Guide
The Intel GMA series is notable as a dominant force in low-cost integrated graphics, with about 90% of PC motherboards sold in early 2007 featuring an integrated GPU. Its significance lies in providing basic graphics capability for netbooks, low-priced laptops, and business computers that did not require high levels of graphics power. The series evolved from the earlier Intel Extreme Graphics and Intel740 discrete units, and its architecture initially relied heavily on the host CPU, leading to poor gaming performance and the derogatory nickname 'Graphics Media Decelerator'. The 4th generation GMA X3000 marked a substantial redesign with unified shader processors and hardware acceleration for video, improving performance for casual gamers. The GMA series ended with the shift to the Platform Controller Hub, giving way to the CPU-based Intel HD and Iris Graphics. Its legacy is that of a ubiquitous but underpowered integrated solution that enabled low-cost computing, while its performance limitations became a well-known benchmark for entry-level graphics.
Did You Know?
- The GMA series was introduced in 2004, replacing the Intel Extreme Graphics series.

Frequently Asked Questions
What is Intel GMA and when did it debut?
Intel GMA (Graphics Media Accelerator) is a line of integrated GPU chips that Intel launched in 2004 to replace the older Extreme Graphics family. Rather than sitting on a discrete card, the GMA is soldered directly onto the motherboard or chipset, so it shares the system's main RAM as its video memory pool.
What role does Intel GMA play in a PC?
It provides basic 2D and 3D acceleration for everyday tasks—browsing, office work, and light media playback—on budget netbooks, low-cost laptops, and corporate desktops. Because it draws from shared system memory (up to 224 MB on the GMA 950 via Intel's DVMT scheme), it keeps the bill of materials low without needing a separate video card.
Why is Intel GMA considered important in PC history?
By the early 2000s, roughly 90 % of all PC motherboards shipped with some form of integrated GPU, and GMA was the dominant Intel option during that wave. It made functional graphics a default feature of inexpensive machines instead of an optional add-on, shaping how most people experienced their first computers.
What were the headline performance specs of the GMA 900?
At a core clock of 333 MHz, the GMA 900 could push a peak pixel fill rate of about 1,332 megapixels per second. That figure was plenty for desktop compositing and video decoding of the era, though it left very little headroom for demanding 3D titles.
