Nvidia Corp. has introduced the first Kepler architecture-based graphics processing unit for mobile computers, the GeForce GTX 660M. Thanks to new power-efficient architecture and 28nm fabrication process, the GK107 graphics processor is projected to offer decent performance while consuming low amount of power.

"Ultrabook users will love the GeForce GT 600M family for its performance and power efficiency," said Brian Kelleher, senior vice president of GPU engineering at Nvidia.

Nvidia Kepler architecture supports modern high-end features like DirectX 11.1, OpenGL 4.2, OpenCL 1.2, stereoscopic-3D, 4 multi-monitor capability, PhysX, multi-GPU, PCI Express 3.0 and so on. The new chips are made using 28nm process technology and feature special optimizations to trim power requirements.

Nvidia GeForce 600M family of graphics processors for notebooks includes both GK107 "Kepler"-based  models, GF114 (40nm), GF116 (40nm), GF119 (40nm) GF117 (28nm) and GF108 (28nm) "Fermi"-based re-branded or re-des graphics solutions. In fact, Kepler/GK107 powers only GeForce GTX 660M, GT 650M, GT 640M and some GT 640M LE. The models GTX 680M, GTX 675M and GTX 670M utilize previous-gen GF114/40nm, GT 635M is powered by GF116/40nm, GT 630M uses GF117/28m, 610M is based on GF119/40nm.

Nvidia GK107 graphics processing unit has 384 stream processors, 32 texture units,16 render back ends and 128-bit memory bus. All currently available mobile Kepler GPUs, except GT 640M LE, are fully-fledged GK107 chips and the only difference between them are clock-speeds of processors and memory.

Nvidia claims that many OEMs are already shipping GeForce 600M Series GPUs with Intel Sandy Bridge notebooks – for example, the Acer Aspire M3-581TG/Acer Timeline M3 Ultra ultrabook features a GeForce GT 640M. Once Intel’s next-generation Core i-series "Ivy Bridge" platform is fully rolled out by the middle of the year, there will be new notebooks with Nvidia Kepler GPUs being offered by every major manufacturer, including Acer, Alienware, Asustek Computer, Dell, Gigabyte, HP, IBM, Lenovo, MSI, Samsung, Toshiba and newcomer Vizio.
