Intel Graphics Media Accelerator (GMA) 4500MHD
The Intel Graphics Media Accelerator 4500MHD (sometimes also called GMA X4500 HD or other combinations) is a DirectX 10 capable onboard graphics adapter in the GM45 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 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.
