The Intel Graphics Media Accelerator, or GMA, is a series of Intel integrated graphics processors built into various motherboard chipsets. These integrated graphics products allow a PC to be built without a separate graphics card, which can reduce cost, power consumption and noise. They rely on the a PC's main memory for storage, which imposes a performance penalty, as both the CPU and GPU have to access memory over the same bus.
