Intel Graphics Media Accelerator (GMA) 900 vs Intel Graphics Media Accelerator (GMA) 500 vs Intel Graphics Media Accelerator (GMA) 950

Intel Graphics Media Accelerator (GMA) 900

The Intel Graphics Media Accelerator 900 (also known as GMA 900) is an integrated (onboard) graphic chip on the Mobile Intel 915GM chipset for Intel processors. It does not support hardware T&L (Transform & Lightning) calculations (which is required for some games).

It supports DirectX 9.0 with Shader Model 2.0 (Vertex Shader are calculated in Software - by the CPU) and OpenGL 1.4. Furthermore, the chip is able to accelerate the decoding of MPEG2 videos and supports Motion Compensation.

The GMA 900 can not be described as a graphics card that is sufficient for gamers. Still Intel published a list  of games that will run (not needingly beautiful) on the notebook. Some old 3D games and especially 2D games should run without problems. The advantage of integrated graphics cards, is that they have a low power consumtion and therefore save battery life. Furthermore, the laptop may stay cooler and more silent than laptops with dedicated graphics cards. For office programs and surfing the performance is more than sufficient.

Currently there are no drivers that support Aero Glass for Windows Vista.

Intel Graphics Media Accelerator (GMA) 500

The Intel Graphics Media Accelerator 500 (also called GMA 500) is a graphics card for embedded products (e.g. MIDs), netbooks and other small mobile devices. It is usually paired with an Intel Atom CPU and designed for video playback tasks (even HD content). The integrated video decoder is able to accelerate MPEG-2, VC-1, and AVC HD videos.

The graphics core is based on a licensed PowerVR SGX core (Power VR SGX535 as in the Apple A4) and is clocked with 100 (UL11L) or 200 MHz (US15L, US15W chipset). The GMA 500 is compatible with DirectX 10.1 and features 4 unified shaders. Still the performance wont be sufficient for playing 3D games.

Intel Graphics Media Accelerator (GMA) 950

The Intel Graphics Media Accelerator 950 (also known as Intel GMA 950) is an integrated (onboard) graphic chip on the Mobile Intel 945Gx chipset for Intel processors. It is a faster clocked version of the GMA 900 and does not support hardware T&L (Transform & Lightning) calculations (which is required for some games). Compared to the GMA 900 it now supports Shader Model 3.0 (instead of 2.0) and can decode 2 HD Streams simultaneously.

It supports DirectX 9.0 with Shader Model 3.0 (Vertex Shader are calculated in Software - by the CPU) and OpenGL 1.4. Furthermore, the chip is able to accelerate the decoding of MPEG2 videos and supports Motion Compensation (2 HD Streams simultaneously). Modern HD videos in MPEG 4 or VC-1 can not be decoded with the graphics card. 

The GMA 950 is integrated in the following chipsets with different rendering clock rates (that affect the 3D performance):

• 945GU: 133 MHz (Lakeport for Intel A100 and A110)
• 945GSE: 166 MHz (for Atom)
• 945GMS: 166 MHz / 250 MHz (1.05V)
• 940GML 166 MHz / 200 MHz (1.05V) - Celeron M (ULV)
• 943GML: 200 MHz
• 945GM: 250 MHz (Calistoga)
• 945G, 945GC, 945GZ: 400 MHz (Lakeport)

Using the GMABooster tool, slower variants can be clocked to 400 MHz to increase the 3D performance (use at your own risk, not supported by Intel!).

The GMA 950 can not be described as a graphics card that is sufficient for gamers. Still Intel published a list  of games that will run (not needingly beautiful) on the notebook (list is for the GMA 900). Some old 3D games and especially 2D games should run without problems. The advantage of integrated graphics cards, is that they have a low power consumtion and therefore save battery life. Furthermore, the laptop may stay cooler and more silent than laptops with dedicated graphics cards. For office programs and surfing the performance is more than sufficient.

The newest drivers support Windows Vista with Aero Glass effects and according to some of our readers it should run fluently.
