As the rumors leaked a couple of weeks ago, NVIDIA unveiled at Computex its GPU architecture based on Kepler the most powerful for the market for laptops, GeForce GTX 680M. The new NVIDIA graphics chip has been selected by many builders to add to their line of high performance laptops. One of these assemblers out there is Alienware, which will offer this GPU in their new gaming notebook for their M18x and WIN M17x.
Rene Haas, vice president and general manager of the NVIDIA notebook division says “GeForce GTX 680M is the fastest mobile graphics unit on the market, but is more than a king of speed. It also offers a whole array of next-generation technology, along with Optimus technology to improve battery life. ”
As expected, GeForce GTX 680M is a true workhorse in technical specifications, although differences between the desktop and laptop models, offering up to 83% performance increase – in the 3DMark 11 results over the GTX 580M Fermi. Like the GeForce GTX 670 – desktop model – GTX 680M integrates 1344 CUDA cores at 720Mhz, 2GB memory and video memory is GDDR5 256-bit interface and speed of 1800Mhz, offering a total bandwidth of amazing 115.2GB / s . The number of processing units is much higher than other mobile GPUs from the 600 series, a mixture of Fermi and other Kepler chips, ranging between 336 and 384 cores.
The main attraction of this new mobile graphics card is the ratio of performance per watt than the previous chip by offering a more efficient architecture and slightly lower clock speeds, which makes this GeForce GTX 680M the perfect candidate to get superior performance in any high-performance notebook, with the exception, of course, the Radeon HD 7000M, from AMD, that soon will be tested against Kepler’s most powerful mobile market card.
