Intel GMA

The Intel Cartoon Media Accelerator, or GMA, is a alternation of Intel chip cartoon processors congenital into assorted motherboard chipsets.

These chip cartoon articles acquiesce a computer to be congenital after a abstracted cartoon card, which can abate cost, ability burning and noise. They await on the computer's capital anamnesis for storage, which imposes a achievement penalty, as both the CPU and GPU accept to admission anamnesis over the aforementioned bus. They are frequently begin on netbook, bargain anthology and desktop computers, as able-bodied as business computers, which do not charge aerial levels of cartoon capability. In aboriginal 2007, 90% of all PCs awash had chip graphics

GMA 900

The GMA 900 was the aboriginal cartoon amount produced beneath Intel's Cartoon Media Accelerator artefact name, and was congenital in the Intel 910G, 915G, and 915Gx chipsets.

The 3D architectonics of the GMA 900 was a cogent advancement from the antecedent Extreme 3D cartoon processors. It is a 4 pixel per alarm aeon architectonics acknowledging DirectX 9 pixel shader archetypal 2.0. It operates at a alarm amount alignment from 160 to 333 MHz, depending on the accurate chipset. At 333 MHz, it has a aiguille pixel fill-rate of 1332 megapixels per second. However, the architectonics still lacks abutment for accouterments transform and lighting and the agnate acme shader technologies.

Like antecedent Intel chip cartoon parts, the has accouterments abutment for MPEG-2 motion compensation, color-space about-face and DirectDraw overlay.

The processor uses altered abstracted alarm generators for affectation and cede cores. The affectation assemblage includes a 400 MHz RAMDAC, 2 25–200 Mpixel/s consecutive DVO ports, and 2 affectation controllers. In adaptable chipsets, up to 2 18-bit 25–112 MHz LVDS transmitters are included.

GMA 950

The GMA 950 is Intel's second-generation cartoon core, which was additionally referred by Intel as 'Gen 3.5 Integrated Cartoon Engine' in datasheets. It is acclimated in the Intel 940GML, 945G, 945GU and 945GT arrangement chipsets. The bulk of video-decoding accouterments has increased; VLD, iDCT, and bifold video bury windows are declared to be handled in hardware.2 However in a affection allegory document3 it is noted, that VLD and iDCT are not accurate until GMA 3100 (on G33 chipsets only). The best bulk alarm is up to 400 MHz (on Intel 945G, 945GC, 945GZ, 945GSE), advocacy pixel fill-rate to a abstract 1600 megapixels/s.

The GMA 950 shares the aforementioned architectural weakness as the GMA 900: no accouterments geometry processing. Neither basal accouterments transform and lighting,4 nor added avant-garde acme shaders are handled in the GMA hardware, these are alone attainable via Software Rendering. The 950 does abutment Accouterments Pixel Shader 2.0 and Software Pixel Shader 3.0 (Not Emulated) but is not able of active avant-garde games
