According to VR-Zone, the GeForce 9 Mobile line should resemble the following:

In addition, we should add the GeForce 9300M G and 9500M GS which are respectively based on the G86 and G84.
As marketing obliges, there is no automatic relation between the GPU and final name of the product (and quite the contrary!). In practice, this can mean that performance differences can be bigger between two cards with almost identical names than models that appear largely unrelated.
In short, many buyers may opt for laptops which have significantly lower performances than expected. Unfortunately, this is something relatively common in the world of notebooks where GPU and/or memory frequencies can be much less than those officially recommended by manufacturers eager to please OEMs. Otherwise, we can see that the G94 which equips the desktop GeForce 9600 have been promoted to the level of GeForce 9700 or 9800.
Finally, for some GeForce 9700Ms as well as for the 96x0M and 9500M G, we find the
G96 while for the entry level there is the
G98.
