Intel Graphics Media Accelerator (GMA) 600 vs Intel Graphics Media Accelerator (GMA) 900 vs Intel Graphics Media Accelerator (GMA) 4700MHD

Intel Graphics Media Accelerator (GMA) 600

The Intel Graphics Media Accelerator 600 (also called GMA 600) is a graphics cards for embedded products (e.g. MIDs), netbooks and other small mobile devices. It is integrated in the Atom Z600 series CPUs and compared to the GMA 500 it features a twice as high clock speed of max. 400 MHz. 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 and is clocked with max 400 MHz. The GMA 600 should be theoretically compatible with DirectX 10.1 and features 4 unified shaders. Because of the missing Windows BIOS support, the Lincroft SOC is currently not able to run Windows (only CE) and therefore supports OpenGL ES 2.0, Open VG 1.0, DirectX 9.L. Another restriction is the max. resolution support of 1366x768 with LVDS and 1024x600 with MIPI.

The performance wont be sufficient for playing demanding 3D games.

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) 4700MHD

The Intel Graphics Media Accelerator 4700MHD (sometimes also called GMA X4700 HD or other combinations) is a DirectX 10 capable onboard graphics adapter in the GM47 chipset of the Centrino 2 platform (Montevina). The chip has no dedicated graphics memory, but takes dynamically an amount from the main memory (up to 384 MB).

Compared to the GMA 4500MHD, the 4700MHD features a higher core clock (plus 107 MHz) and is therefore a bit faster. Compared to the predecessor GMA X3100, the GMA 4500MHD has two more shaders and a 33 MHz higher core clock speed. Therefore, the chip is noticable faster than the older one (especially in 3DMark06). Still, the performance is just on par with the entry level dedicated graphics cards and therefore not suited for demanding games.

A new feature of the GMA chip, are the integrated HD video-decoding functions. The GM45 is able to decode HD-videos in the formats AVC, VC-2, and MPEG-2 to help the CPU. This way a Blu-Ray playback should also be possible with a low end CPU.
