NVIDIA GeForce Go 7950 GTX SLI vs NVIDIA GeForce Go 7900 GS
NVIDIA GeForce Go 7950 GTX SLI► remove
Two NVIDIA GeForce Go 7950 GTX graphic cards in SLI combination grant highest performances coupled with highest current consumption. So, the performance is similar to the top DirectX 9 desktop graphic cards (without SLI in desktop).
The 7950 GTX is the top graphic card of the series 7000 from NVIDIA for laptops. It offered at the time of presentation a high performance to play all DirectX 9 games in high resolutions and details. Especially, regarding Antialiasing and Anisotrop filters the combined cards are clearly better than single cards. They are used for big and heavy laptops (because of the heat creation, at moment only in a 19" notebook). The card combination was succeeded by the 8800M GTX SLI card combination.
Due to the fact, that the SLI combination renders each frame on a different graphics card, the frametimes between two frames may differ. Therefore, the game at 30fps may stutter a bit, the so called micro stuttering.

This 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.
