NVIDIA GeForce Go 7900 GTX vs vs NVIDIA GeForce Go 7900 GS
NVIDIA GeForce Go 7900 GTX
► remove from comparisonNVidia GeForce Go 7900 GTX is the predecessor of the 7950 GTX and has still a very good DirectX 9 performance. The card enalbes the user to play e.g. Doom3 in 1600x1200 fluently. The card was used in large notebooks (because of heat issues).
The chip also features the PureVideo Technology but has less features as the PureVideo engine in the current 8600M GT chip. > Comparison of PureVideo features
NVIDIA GeForce Go 7900 GS
► remove from comparisonThis is the smaller version of the 7900 GTX with less shader- and vertex-pipelines and less current consumption. Nevertheless it is not apt for small notebooks.
The performance is near to the 7800 GTX, but needs clearly less energy. It is used for 17" notebooks, because a lot of heat arises.
The chip also features the PureVideo Technology but has less features as the PureVideo engine in the current 8600M GT chip. > Comparison of PureVideo features
Compared to the Desktop GeForce 7900 GS graphics card the mobile version has a smaller core and memory speed (375 versus 450 MHz chip, 500 versus 660 MHz memory speed) and is therefore a bit slower.
