NVIDIA GeForce Go 7950 GTX vs NVIDIA GeForce Go 7900 GTX SLI
NVIDIA GeForce Go 7950 GTX► remove
The NVIDIA GeForce Go 7950 GTX is top of the mobile graphic cards line from NVIDIA (of the 7000 series) and successor of the 7900 GTX graphics card. It enables the user to play all games from 2006 fluently in the highest resolutions and options. As a consequence, the heat is correspondingly high. Therefore it can be used only in DTR laptops (17"). At moment, there is nothing better for gamers (except the SLI version with 2 cards).
The performance can be compared partially even with the Desktop 7950 GT video cards (partially a bit better, according NVIDIA). Therefore, the Geforce Go 7950 GTX is able to display actual games like F.E.A.R., Company of Heroes, or Call of Duty 2 fluently in high details and high resolutions.
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 GTX SLI► remove
Two NVIDIA GeForce Go 7900 GTX graphics cards are bounded by SLI. This showed the best benchmark and game scores (in 2006 and before the introduction of the 7950 GTX SLI) but also needs twice as much current as a single 7900 GTX graphics card. Therefore, the battery runtime is very low!
It is one of the best mobile graphic cards line from NVIDIA (of the 7000 series). It enables the user to play all current (10/2006) games fluently in the highest resolutions and options e.g. Half Life 2 - Lost Coast (max settings inkl HDR) with 65 fps with 4x antialiasing and 8x anisotrop filters. Even with antialiasing and anisotrop filters the SLI combination clearly is better than single cards. The heat is correspondingly high. Therefore it can be used only in DTR laptops (at moment only one 19" laptop). At moment, there is nothing better for gamers.
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.
The features of the SLI combination is comparable to a single GeForce Go 7900 GTX.
The performance can be compared partially even with the Desktop 7950 GT video cards (partially a bit better, according NVIDIA).
