Windows 7 - Mobile Intel 4 Serie GS45 & GM45 Express Chipset Familly

I was wondering and looking at a previous post made here, but couldn't find it back...so i'm asking now some infos to clear a state i need.

Got either the Intel GMA 4500MHD Driver for Mobile card (switchable with an Ati card)

I have both listed as Mobile Intel 4 Platform GM45 (GPU-Z) and GS45 (CPU-Z)...

My need to know if is it possible both are listed, and if it native to this Chipset Familly to be named double.

On the Intel Site they do both looks the same...their data-sheet doesn't mention it being together.

Is that because of the SouthBridge Intel ICH9-M Controler and the Driver for Mobile Intel 4500MHD both installed???

The post i was looking for explained a little...but...

GM45 and GS45 are the same chip just diff interface!! so there both right

its the same as Nforce 4 and Geforce IGP 6150 on micro motherboards

Thanks for your reply...I might have again a closer look at Intel datasheet
