Geared towards desktop replacement notebooks, and their thin and light ultrabook cousins, the GeForce GTX 680M appears to have nearly the equivalent power to the desktop GTX 670 — 1,344 graphics cores with a 256-bit memory bus. NVIDIA says that the maximum clock ceiling of 720MHz (this is lower than the 915MHz offered by its desktop iteration).
“The GeForce GTX 680M is the fastest mobile GPU ever, but it’s more than just a speed king,” said Rene Haas, vice president and general manager of the notebook business unit at NVIDIA in a statement. “It also offers an entire arsenal of next-gen gaming technology, along with Optimus technology for extended battery life.”
“The intense focus on performance and technology engineered into the 2GB GDDR5 NVIDIA GeForce GTX 680M is a perfect match for the Alienware M17x and M18x laptops,” offered Frank Azor, Alienware General Manager, in a statement. “Whether a single graphics card on the 17x or dual GTX 680M’s on the M18x, Alienware owners are going to love having this much power at their fingertips.”
NVIDIA is boasting that this mobile graphics powerhouse will offer a range of features equivalent to a desktop card. According to NVIDIA, these features include:
- Adaptive V-sync – newly developed technology for a smoother gameplay experience
- Advanced AA modes – for crisper images, including NVIDIA FXAA and new TXAA
- NVIDIA Optimus technology – enabling extra-long battery life by automatically switching on the GPU only when it is needed
- NVIDIA PhysX support – for accelerated in-game physics
- NVIDIA 3D Vision 2 technology – for bigger, brighter, more comfortable 3D gaming
- NVIDIA 3DTV Play software – for connecting notebooks to 3DTVs for the most immersive gaming experience to be had in a living room
- High-performance NVIDIA Verde notebook drivers – offering day one game support and maximum compatibility
- NVIDIA SLI technology – make the fastest notebook GPU even faster with up to double the gaming performance
- NVIDIA CUDA technology support – for high-performance GPU computing applications
NVIDIA’s line of Kepler GPUs for mobile platforms currently consists of the GeForce GTX 680M, GTX 660M, GT 650M, GT 640M and GT 635M.
AMD is expected to launch a chipset, the Radeon HD 7970M, to compete with NVIDIA’s mobile Kepler offerings later this week at Computex.
