NVIDIA GeForce 8400M GS vs vs NVIDIA GeForce 8400M GT
NVIDIA GeForce 8400M GS
► remove from comparisonNVidia GeForce 8400M GS is the DirectX 10 capable successor of the GeForce Go 7400 for laptops and technologically a slower 8400M GT video card (because of the smaller 64 Bit memory bus). The performance is slightly above the 7400 and, therefore, it can represent current (not very demanding) games fluently with reduced details / resolutions. Demanding games like Crysis can only be run in very low details and resolutions. For people who play occasionally, it may be sufficient.
The particularity of this video card are the "Unified Shader". Pixel- and vertex-shaders do not exist any more but 16 of the so called stream processors do the graphic work.
One advantage of the GeForce 8000 series is the integrated PureVideo video processor. It can support the CPU in decoding H.264, VC-1, MPEG2, and WMV9 encoded videos in HD quality > PureVideo Product Comparison
Compared to desktop cards, the 8400M GS can be compared to the 8400 GS which has a 50 MHz higher core clock (and is therefore a bit faster).
NVIDIA GeForce 8400M GT
► remove from comparisonNVidia GeForce 8400M GT is the DirectX 10 capable successor of the GeForce Go 7400 for laptops and technologically a slower 8600M GS video card. The performance is slightly above the 7400 and therefore it can represent current games fluently with reduced details / resolutions. For people who play occasionally, it may be sufficient.

Compared to desktop graphics adapters, the 8400M GT is a bit slower than the 8500 GT (because of the lower memory speed).
