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). The chip has no dedicated graphics memory, but
takes dynamically an amount from the main memory (up to
384 MB).
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.
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
olderone (especially in 3DMark06). Still, the performance is
just on par with the entry level dedicated graphics cards and
therefore not suited fordemanding games. Some older games
like Fear can be played in low details and low resolutions (see
"Gaming Performance" below).
Compared to other modern integrated graphic cards like
the Nvidia GeForce 9400M (G 102MNVIDIA GeForce G 105M)
or AMD ATI Radeon HD 3200, the GMA 4500M HD noticably
slower and provides less optimized drivers for games.
The version in the GS45 can be clocked lower (320 versus
533 MHz) and support only FSB 800 (instead of FSB
533/1066). Furthermore, switchable graphics are only
supported in the GM45 chipset. The GE45 has the same
features as the GM45, and aditionally is certified by
Macrovision.
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 (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). Because of the lower clock rate, the
4500M performs a bit worse in games and is not capable of
decoding Blu-Ray videos fluently.
