Yesterday, Nvidia officially launched its new line of GPUs for notebooks:

All of these products are destined for the mid-entry level and there is nothing revolutionary as the GeForce 9650M GS strangely reminds us of the
8700M GT and therefore has lower performances than an aging 8600 GTS.
Moreover, we noticed several other curious items. As we write these lines Nvidia’s site mentions 8 calculation units for the GeForce 9300M GS and 16 for the 9300M G. In terms of frequencies, the company with the green chameleon logo isn’t taking too many risks, because they say nothing (or almost) for a number of models. For the others, we have listed the official specifications, but unfortunately laptop manufacturers often offer solutions under these names although with lower GPU and memory frequencies due to cost and/or heat dissipation reasons. One important point is that the 9100M G and 8200M G are actually IGPs or "mGPUs" which is not without repercussions on the available memory bandwidth.
The press release reminds us that the main innovations are support of Hybrid SLI and GeForce Boost which may indeed be of great interest in notebooks. A new version of the PureVideo HD engine should also be included but the way (or at least partly so) that
GeForce 9xx0Ms use the G8x remains rather vague. Finally, they can fit into MXM 3.0 type modules.
