Press Release :

NVIDIA today announced the world's fastest notebook graphics processing unit (GPU), the NVIDIA® GeForce® GTX 580M. Available now in the Alienware M18x, the new GPU sets new standards in industry leading benchmarks and games. It will also be available soon in the Alienware M17x notebook along with NVIDIA Optimus™ technology.

"The best game support. The best gaming features. The best gaming performance available anywhere. That's the essence of the GeForce GTX 580M," said Rene Haas general manager of notebook products at NVIDIA. "With power like this, you can turn all the knobs to 11."

The first notebook PC to feature the GeForce GTX 580M, the Alienware M18x offers the option of two GeForce GTX 580M GPUs in one system for up to double the gaming performance, using NVIDIA SLI® technology. Not to be outdone, the Alienware M17x will offer the GeForce GTX 580M along with NVIDIA Optimus™ technology and will deliver 5 hours of battery life in Facebook, and 100 frames per second performance in Call of Duty: Black Ops.

"Gamers aspire to experience games at their highest settings," says Eddy Goyanes, product marketing manager for Alienware. "Alienware activates the technology designed to enable those aspirations. With the launch of the GeForce GTX 580M on the Alienware M17x, and a dual card option on the M18x, that synergy continues - Alienware delivers the ultimate gaming experience."

GeForce GTX 580M GPUs are the fastest Microsoft DirectX 11 notebook GPUs on the market, offering up to six times the tessellation performance of any other notebook GPU. They are also more efficient, with up to 20 percent better performance per watt than the previous generation.

NVIDIA also introduced the NVIDIA GeForce GTX 570M GPU, which offers 20 percent faster performance than the previous generation product it replaces.[iv]
