The NVIDIA GeForce 8600M GT SLI are two single DirectX10 capable 8600M GT graphic cards in SLI combination. Depending on the particular games, the combination is about 0-60% faster than one single graphic card. DirectX9 games can be played with higher resolutions and high details fluently (if SLI is supported). DirectX 10 games are very demanding (e.g. Crysis and World n Conflict) and can't be played in highest DirectX 10 detail levels fluently, at moment. Perhaps, that will improve by later driver optimizing.
The 8600M is one of the best laptop-GPUs worldwide, which support DirectX 19 and H.264-decoding and accelerate HD-films.
A particularity of the graphic card are the "Unified Shaders" of ALUs (Arithmetic Logical Unit). There don't exist any more dedicated pixel- and vertex shaders but 32 so called Stream processors maintain the upcomming graphic work (which was done by the pixel and vertex Shaders, up to now). The advantage is that there is no idle time of the ALUs. The Stream processors of NVIDIA are 1-dimensional (1D) and can make one skalar operation per cloc with a MADD operation (addition and multiplication) and a MUL-operation (multiplication). Moreover, NVIDIA clocks the Shader-ALUs higher than the remaining chip.
The memory clock of each GeForce 8600M GT of the SLI combination depends on the implemented memory type: 400 MHz with GDDR2 and 700 MHz with GDDR3.
Compared with dektop graphic cards, the 8600M GT in SLI combination of the GDDR3 laptop version is scarcely below two 8600 GT SLI (each desktop card has a higher chip clock).
