NVIDIA GeForce 9800M GT SLI

NVIDIA GeForce 9800M GT SLI

The laptop graphic solution Nvidia GeForce 9800M GT SLI consists of two 9800M GT in SLI comination. Therefore, the performance can be compared with the 8800M GTX SLI. According to the SLI support, the performance is 0-40% better than a single 9800M GT. Micro stutterings can occur like with all SLI combinations.

The Nvidia GeForce 9800M GT is a reduced GTX laptop chip with only 96 shaders (instead of 112 of the GTX chips) and is based on the G92 architecture. Like with the 8800M GTX, the chip is processed in 65nm and is equal according the technical data. The amount of available shaders is doubled due to the use of two 9800M GT cards. The available memory is not doubled because the same content is stored at each single card.

Like all DirectX 10 graphic cards, the GeForce 9800M GT SLI "Unified Shader". There don't exist dedicated pixel- or vertex shaders but 2x96 so called stream processors make the graphic work (which has been done by the pixel- and vertex shaders). Furthermore, all shader units are higher clocked than the chip.

 

HybridPower allows the switching between onboard graphics (with Nvidia chipset) and dedicated graphic card (9800M GT) in Windows Vista. Therefore, the dedicated graphic card can be disabled, if it is not needed (while Office or internet surfing). So, energy can be saved. Hybrid Power can be switched in Vista (at moment manually by tool, later by driver according to Nvidia). GeforceBoost does not work with the 9800M GT because the connection with the chip set (SLI)  would not result in an increase of performance.

The performance increase of the two 9800M GT in SLI mode is between 0% and 40%. For current DirectX 10 games, like Crysis, World in Conflict, Bioshock or Age of Conan, the performance of the graphic card is sufficient.

The phenomenon micro stutterings can occur in all SLI systems. The user sees stutterings despite high frame rates. This is the result of different time delays between two images.

An advantage of the GeForce 9000 series is the integrated PureVideo HD video processor. This helps with the decoding of H.264-, VC-1-, MPEG2- and WMV9 video material in HD quality and therefore reduces the load of the CPU.

The current consumption of up to 130 Watt (consumption of both MXM boards with memory) allows the use of the card only in laptops with an efficient cooling system. Therefore, the 9800M SLI series can only be found in big and heavy laptops. Considerable emissions can be found with load.
