Intel Graphics Media Accelerator (GMA) 500 vs Intel Graphics Media Accelerator (GMA) 4700MHD
Intel Graphics Media Accelerator (GMA) 500► remove
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) 4700MHD► remove
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.
