A critical component of the GeForce 400M Series is support for NVIDIA Optimus technology, which enables extra-long battery life by automatically switching on and off the GPU so that it runs only when needed.





The NVIDIA GeForce 400M series are the first notebook processors designed with NVIDIA's Fermi architecture and built from the ground-up for Microsoft DirectX 11. They power notebooks with great battery life, and support high-definition video playback, fast Web browsing, 3D and gaming. Nvidia claims that the new GPUs offer up to 5X faster HD video uploads to Facebook and up to 10X the game performance on the year's top title StarCraft II.



The GeForce 400M series is also able to deliver stereoscopic 3D images for gamers, movie-lovers and photo enthusiasts when configured with NVIDIA 3D Vision glasses and a 3D display. Notebook models featuring the GeForce 400M series and NVIDIA 3D Vision glasses will be available soon after launch, including the Acer Aspire 5745DG with GeForce GT 425M and the Asus G53Jw with GeForce GTX 460M. In addition, by including support for NVIDIA 3DTV Play, users can attach their notebook to a brand new 3D TV and enjoy all the latest 3D content including the hottest games in the comfort of their living room.

NVIDIA GeForce GPUs also offer "Graphics Plus" features such as:

* NVIDIA 3D Vision support, for 3D environments
* PhysX support, for experiencing games with realistic physics effects
* CUDA support, for GPU computing applications
* NVIDIA Verde notebook drivers, for system stability and optimal performance
* Support for NVIDIA 3DTV Play software, for connecting 3D Vision-based notebooks and desktops to a 3D TV.


Acer, Asus, Dell, Lenovo, Samsung, and Toshiba all announced today support for 400 Series GPUs, with more OEMs announcing soon.
