NVIDIA has taken the wraps off its new notebook GPU, which will be the new flagship model. The GeForce GTX 680M is the fastest, most advanced notebook GPU ever thanks to its Kepler architecture. The GPU has 2GB of GDDR5 RAM clocked at 1800MHz on a 256-bit bus, 1344 CUDA cores, and a core frequency of 720MHz. The GTX 680M will help deliver the best performance possible for all the latest games, including 3D titles thanks to 3D Vision 2 and 3DTV Play. There will also be Adaptive V-sync, advanced AA modes, PhysX support, and even CUDA support to bring the 680M in line with its desktop brothers. NVIDIA Optimus technology allows you to switch to the integrated GPU so you can save on battery life outside of gaming, ensuring you will not have to worry about straying from the outlet. Alienware's M17x and M18x will make use of the GTX 680M, with the M18x including single and SLI configurations. The GPU will also appear in the MSI GT70 gaming notebooks and machines from Ava Direct, Maingear, and Origin. The notebooks should be available by the end of June.
