Intel Graphics Media Accelerator (GMA) 4700MHD vs Intel Graphics Media Accelerator (GMA) 600
Intel Graphics Media Accelerator (GMA) 4700MHD► remove from comparison
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.
Intel Graphics Media Accelerator (GMA) 600► remove from comparison
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.
