Nvidia now stakes claim to the title of the world's fastest notebook graphics processing unit with the GeForce GTX 580M. How fast are they? In SLI, they're fast enough to play Crysis 2 at max settings in 1080p with DirectX 11 effects and high-resolution textures on (check out the video below for proof of that).
The first notebook PC to feature the GeForce GTX 580M is the Alienware M18x with the option to go SLI. The Alienware M17x will offer a bit more flexibility with the GeForce GTX 580M along with Nvidia Optimus technology and will deliver 5 hours of battery life when using the integrated graphics instead of the discrete GPU.
Nvidia also introduced the GeForce GTX 570M GPU, which offers 20 percent faster performance than the previous generation product it replaces.
