NVIDIA GeForce 9800M GTX The Nvidia GeForce 9800M GTX is a graphics adapter for laptops and based on the G92 core (as the 8800M GTX but with 112 shader processors). The chip is produced in 65nm and because of the high shader count, the current consumption (75 Watt of the MXM board) is very high and only suited for big laptops with a good cooling solution. Later, the GPU was succeeded by the GTX 260M, which was produced in 55nm (G92b) and needed less power. The performance of the chip is noticeable better than the 9800M GT / GTS because of the additional shader units (see benchmarks below). Therefore, DirectX 10 games of 2008 should all be playable in high details. As all cards with DirectX 10 capabilities, the GeForce 9800M GTX renders the 3D images using "Unified Shaders". There don't exist any more dedicated pixel- and vertex shaders but 112 so called stream processors make the graphic work (which has been done by pixel and vertex shaders in former days). Furthermore, the shader units are higher clocked than the chip (1250 MHz). An advantage of the GeForce 9000 series is the integrated PureVideo HD video processor. It is able to help with the decoding of H.264-, VC-1-, MPEG2- and WMV9 video material in HD quality and eases the CPU. In conjunction with the Nvidia 9100M G integrated graphics, the 9800M GTX supports Hybrid-SLI (only HybridPower). HybridPower is a technique to choose between the integrated and dedicated graphics core, if performance or battery runtime is needed. This works only in Windows Vista. Up to now the user has to use a tool to switch between the GPUs. Later Nvidia wants to switch automatically in the drivers. GeForceBoost is not supported with this card, as there would be no performance gain to combine the integrated GPU with the 9800M GTX. Compared to desktop graphics cards, the 9800M GTX should be a bit slower than the GeForce 8800 GT (which has a higher memory clock rate).
