Intel Graphics Media Accelerator (GMA) X3100 vs Intel Graphics Media Accelerator (GMA) 4500M vs Intel Graphics Media Accelerator (GMA) 4700MHD
Intel Graphics Media Accelerator (GMA) X3100► remove from comparison
Intel Graphics Media Accelerator (GMA) X3100 is an integrated (onboard) graphic chip on a Mobile Intel 965GM (with 500 MHz core speed) and 960GM (400 MHz) chipset (for Merom = Core 2 architecture). It is the successor of GMA 950. Most interesting is the integration of a fully programmable pipeline. Due to the integration of DirectX9 and DirectX 10 features (with drivers later than 126.96.36.1992), HDR and Hardware Transform & Lighning (T&L) - predecessor only had Software T&L - should be ready for Windows Vista Premium (support Aero Glass fully). Respective the data, the peformance should be clearly better than GMA 950.
The 13.5 Watt current consumption is relatively low, because it includes all chipset functions (therefore, this value is not compareable to dedicated graphics cards).
Intel Graphics Media Accelerator (GMA) 4500M► remove from comparison
The Intel Graphics Media Accelerator 4500M (GMA 4500M) (sometimes also called GMA X4500 M) is a DirectX 10 capable integrated shared memory graphic card for laptops. The mGPU is integrated in the Intel GM40 and GL40 chipsets and designed for cheap laptops. The graphics card is also called Mobile Intel(R) 4 Series Express Chipset Family in the Intel drivers.
Compared to the GMA 4500M HD, the 4500M features a slower core clock (400 MHz versus 533MHz) and is thus a bit slower in games.
The chip itself is capable of supporting the CPU to decode HD videos, but because of the slower clock rate, the 4500M has troubles decoding 1080p videos fluently and therefore has no full Blu-Ray logo support.
The gaming performance of the 4500M is not really good. Only less demanding 3D games and very old games may run fluently in low detail settings. Sims 3 and F.E.A.R. for example achieved 30 fps (with stutters) in low deatails and low resolustions (combined with a fast CPU). 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. Still the power consumption of the chip is quite competitive, so it may be the right choice for office tasks.
Intel Graphics Media Accelerator (GMA) 4700MHD► remove from comparison
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.
