Nvidia's mobile GPU lineup has expanded today with the introduction of five new high-end products in the GeForce 9M series: the GeForce 9700M GT, 9700M GTS, 9800M GTS, 9800M GT, and 9800M GTX. Not only these new cards promise improved gaming performance, but also to help save power and increase battery life.

At the top end sits the flagship GeForce 9800M GTX, with a core frequency of 500MHz and 112 stream processors each running at 1250MHz. The card is based on the same G92 core of the previous-generation GeForce 8800M GTX but has a higher 420 gigaflops floating-point arithmetic rating. Next up is the 9800M GT and 9800M GTS, both based on the G94 core with a frequency of 500MHz - oddly, the 9800M GT appears to have better specs than the 9800M GTS with 96 stream processors compared to 64 on the latter.

The 9700M series includes the GeForce 9700M GTS and lower end 9700M GT. All these new models share many of the same features as cards announced early last month when the GeForce 9M line was unveiled, including Nvidia's Hybrid SLI and Hybrid Power to save battery life.
