NVIDIA GeForce 9500M GS vs NVIDIA GeForce 9500M G
NVIDIA GeForce 9500M GS► remove
The GeForce 9500M GS is a middle class graphics card from the GeForce 9000M series and the successor of the 8600M GT GPU. Benchmarks show an average 10% increase of frame rates in all games because of internal optimizations (compared to a 8600M GT with the same GPU and memory clock). According to Nvidia the card should also have a lower current consumption.
The card offers full DirectX 10 hardware acceleration, but is not fast enough to render DirectX 10 effects of demanding games, like Crysis, fluently.
The particularity of this video card are the "Unified Shader". Pixel- and vertex-shaders do not exist any more but 32 of the so called stream processors do the graphic work (which up to now pixel- and vertex shaders did).

The Nvidia GeForce 9500M G is the successor of the 8600M GS as it also featuresonly 16 unified shaders (the 9600M series features 32). Compared to the8600M GS, the 9500M G has an improved PureVideo HD engine (VP3), supports Hybrid-SLI and needs less current (because of the 65nm process).
In conjunction with the Nvidia 9100M G integrated graphics, the 9500M G supports Hybrid-SLI (HybridPower and GeForceBoost). HybridPower is a technique to choose between the integrated and dedicated graphics core, if performance or battery runtime is needed. This works only in Windows Vista. Up to now the user has to use a tool to switch between the GPUs. Later Nvidia wants to switch automatically in the drivers. GeForceBoost uses the integrated graphics core of the 9100M G and the dedicated of the 9500M G in SLI mode to achieve better frame rates.
As the 8600M GS, the 9500M G features 16 stream processors that do the work of the former dedicated pixel- and vertex-shaders. The unified shaders of Nvidia are 1-dimensional (AMD has 5-dimensional shaders which leads to the higher number of shaders).
The desktop GeForce 9500 graphics card is not compareable to the mobile 9500M G, because it has 32 stream processors (compareable to the 9600M series).
