NVIDIA GeForce 8700M GT SLI
The NVIDIA GeForce 8700M GT SLI are 2 DirectX 10 capable graphic cards, which are combined by SLI. Technically, each card contains 32 Stream processors like the 8600M GT but the core -m Shader- and memory clock is higher. Therefore the performance of each single card is somewhat higher than the 8600M GT (due to NVIDIA press releases much higher) and therefore should be sufficient for all current games in high resolutions. The SLI combination does not bring double performance and depends on the support in the game.
The 3d Mark values are very good (like with all graphic cards of the 8000 series). Nonetheless, the 128 bit Bus of each single graphic card reduces the gaming performance in high resolutions (and with activated Antialiasing). For example, the SLI combination does not achieve the values of a single 7950 GTX in F.E.A.R.. However, it is the fastest graphic solution for laptops with DirectX 10 support and allows to play all newest DirectX 10 games fluently (altough not in high details).
A particularity of the video card are the "Unified Shaders". There don't exist any more so called Stream processors but 32 so called Stream processors make the upcoming graphic work (which was done by pixel and vertex Shaders, up to now).
Drivers tell that the 8700M GT is called NB8E-SE (8800M GS) internally.
