NVIDIA GeForce GTX 280M SLI

The Nvidia GeForce GTX 280M SLI is a graphics solution that combines two Nvidia GeForce GTX 280M cards in an SLI setup. As not every game supports SLI efficiently, the performance increase compared to a single card is only about 0-40%. The most frequently used technique is Alternate Frame Rendering (AFR), where one card renders every odd frame while the second card renders every even frame. Due to the SLI setup, users may experience micro stuttering due to the irregular delays between sequential frames.

Each of the two GeForce GTX 280M is based on the G92b core and is produced in 55nm. It features the full 128 pipelines of the G92b and is therefore more comparable to the desktop 9800M GTX+ than the desktop GTX 280.

The Nvidia GeForce GTX 280M SLI is bundled with the GeForce 9400M G chipset (for laptops based on the Core 2 Duo) and therefore supports HybridPower if supported by the manufacturer. With HybridPower, both GTX cards can be disabled and only the chipset graphics core can run, leading to longer battery life (and possibly less fan noise). Modern Core i7 laptops use an Intel chipset and do not support HybridPower.

Since there are two GTX 280 cards active in SLI, the electric current consumption and exhumed heat are about twice as much as what a single GTX 280M can produce. Due to the large power and cooling requirements, this SLI combination is usually reserved for large desktop replacement (DTR) laptops (like the Alienware M17x).
