The Nvidia GeForce GTX 285M SLI is a graphics solution that combines two Nvidia GeForce GTX 285M with a SLI connection. As not every game supports SLI sufficiently, the performance increase compared to a single card is only 0-40%. The most used technique is, that every card renders a single image. Therefore, at frame-rates between 20-30 fps the SLI solution may suffer from micro stuttering (because of the different frametimes the two cards deliver).

Each of the two GeForce GTX 285M is based on the G92b core and therefore produced in 55nm. It features the full 128 pipelines of the G92b core and is therefore compareable to the desktop 9800M GTX+ and not the desktop GTX 280.

The Nvidia GeForce GTX 285M SLI in laptops with Core 2 Duo CPUs is bundled with the GeForce 9400M G chipset and therefore supports HybridPower (if the manufacturer enables it). With Hybrid Power, both GTX cards can be disabled and only the chipset graphic core is running, leading to a much better battery runtime (and possibly less noise from the fans). Modern Core i7 laptops are using an Intel chipset and wont support Hybrid Power.

The current consumption and created heat is twice as much as a single GTX 285M produces (because of the two cards) and therefore the SLI combination can only be found in large DTR laptops (like the Alienware M17x).
