The GM45 is able to decode HD-videos in the formats AVC, VC-2, and MPEG-2 to help the CPU. The GE45 has the same features as the GM45, and aditionally is certified by Macrovision.Ī new feature of the GMA chip, are the integrated HD video-decoding functions. Furthermore, switchable graphics are only supported in the GM45 chipset. The version in the GS45 can be clocked lower (320 versus 533 MHz) and support only FSB 800 (instead of FSB 533/1066). Some older games like Fear can be played in low details and low resolutions (see ' Gaming Performance' below).Ĭompared to other modern integrated graphic cards like the Nvidia GeForce 9400M ( G 102M NVIDIA GeForce G 105M) or AMD ATI Radeon HD 3200, the GMA 4500M HD noticably slower and provides less optimized drivers for games. Still, the performance is just on par with the entry level dedicated graphics cards and therefore not suited for demanding games. Therefore, the chip is noticable faster than the older one (especially in 3DMark06). The 400MHz clocked version of the 4500MHD found in the GL40 and GS40 chipsets, is called GMA 4500M (without the HD) and has a worse performance in 3D games and video decoding.Ĭompared to the predecessor GMA X3100, the GMA 4500MHD has two more shaders and a 33 MHz higher core clock speed. The graphics card is also called Mobile Intel(R) 4 Series Express Chipset Family in the Intel drivers. The chip has no dedicated graphics memory, but takes dynamically an amount from the main memory (up to 384 MB). 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, GE45 and GS45 chipset of the Centrino 2 platform (Montevina).
