![]() ![]() Because of the lower clock rate, the 4500M performs a bit worse in games and is not capable of decoding Blu-Ray videos fluently. ![]() This way a Blu-Ray playback should also be possible with a low end CPU (only with the 533 MHz clocked version in the GM45 and GS45).The graphics core in the GL40 and GS40 chipset with a lower core speed of 400 MHz is called GMA 4500M (without the HD). The GM45 is able to decode HD-videos in the formats AVC, VC-2, and MPEG-2 to help the CPU. Therefore, the chip is noticable faster than the older one (especially in 3DMark06). The graphics card is also called Mobile Intel(R) 4 Series Express Chipset Family in the Intel drivers.The 400MHz clocked version of the 4500MHD found in the GL40 and GS40 chipsets, is called and has a worse performance in 3D games and video decoding.Compared to the predecessor GMA X3100, the GMA 4500MHD has two more shaders and a 33 MHz higher core clock speed. ![]() The chip has no dedicated graphics memory, but takes dynamically an amount from the main memory (up to 384 MB). Intel Graphics Media Accelerator (GMA) 4500MHDThe 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). Still the power consumption of the chip is quite competitive, so it may be the right choice for office tasks. 2D applications, games and Windows Vista / Windows 7 Aero are supported without any performance problems.Compared to other modern integrated chipsets like the GeForce 9400M or the Radeon HD 3200, the 4500M is clearly the slowest especially for 3D games. ![]()
