Yeah I hadn't looked at specs on that, and they're of course doing their best to keep people from easily seeing what plain old Geforce chip they used for their "workstation" class products so putting the FX on there when that's 2 generations old naming.
It most likely is a 7300GS, but it looks like it might have a slightly lower clock speed on memory in GPU, a tiny bit of difference. Not uncommon when trying to ensure stable operation and especially when trying to use it on a mobile product.
