NVIDIA GeForce Go 7950 GTX SLI vs NVIDIA GeForce Go 7900 GS SLI
NVIDIA GeForce Go 7950 GTX SLI► remove from comparison
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.
NVIDIA GeForce Go 7900 GS SLI► remove from comparison
Two NVIDIA GeForce Go 7900 GS graphics cards are bounded by SLI. This shows only in SLI supported games a clear performance advantage and makes it partially faster than a GTX version. The smaller version of the 7900 GTX with less shader- and vertex-pipelines and according data sheet less current consumption. It is only useful for big laptops, because of the high current consumption of each graphic card.
Current games like Far Cry, Splinter Cell - Chaos Theory, Oblivion, Call of Duty 2 or Half Life 2 - Lost Coast can be played with high details and resolutions without any problem. Antialiasing and anisotrope filter can be set in all games except Oblivion (with >30fps).
