NVIDIA has announced their newest line-up of notebook GPUs, the GeForce 600M series, designed to be used in next generation Intel Ivy Bridge equipped laptops. NVIDIA’s newest GPUs promise to deliver unmatched performance and best-of-market power efficiency, allowing thinner and lighter laptops (e.g. Ultrabooks) to have high-end gaming experiences. The new GeForce 600M series include the NVIDIA GeForce GTX 675M and GeForce GTX 670M (both which are based on improved Fermi chips), and the GeForce GTX 660M; these models boast the most power and best gaming performance. The GeForce GT 650M, GeForce GT 640M, and GeForce GT 640M LE are categorized as their mid-level “performance” models equipped with “Kepler” GPU architecture. The lower end GeForce GT 620M model is recommended for casual consumers.

There are two features that make this a must buy for gaming enthusiasts: The enhanced battery life, which has the best performance per watt of any notebook GPU to date, and its ability to switch between dedicated and integrated graphics using the Nvidia Optimus technology. Compared its predecessor, the 500M series, the 600M cards are “twice as efficient”, which boast faster frame rates and improved rendering on chips that draw less power. As a result, this increases battery life, reduces heat and noise output, and gives manufacturers the ability to design super slim models without giving up performance.
