XPS 1640 using M96(4650) or M96-XT(4670)???

Hey guys:
I'm looking my XPS 1640 using GPU-Z today, and I'm really confused about the GPU code. It reads out M96, which should be mobility radeon 4650 according to this amd website:

http://developer.amd.com/drivers/pc_vendor_id/pages/default.aspx

A right mobility 4670 should have a gpu code M96-XT. The wired thing is that the rest things, gpu clock, memory clock, device id are all right. Just for the concern, did dell give me an overclocked 4650 instead of 4670 which it should have give me?

 

i dont know anything about ati cards.... but go to device manager and see what it says under the display driver, it should say your whole gpu's name...
thats how you know what you have

 

I believe that's just the name that the installed driver gives... this goes by vendor ID and hardware ID i believe

 

most likely its not gona install correctly if its wrong driver, like I said I dont know much about ati

I have intergrated Nvidia Geforce 9400mg... and when installing the driver, the installation file is for all 9M series video cards, so when the program installs the video driver it knows which card I actually have... so under the name it appears as 9400mg.. not 9200m 9300 or whatever actually exist.

So maybe it works the same for ati??

But still check the device manager it should give you some results

 

it's M96 XT for sure, i think it's gpuz's fault that it gives the wrong name to the hw id.
btw M96 XT is an overclocked M96, so there's not a huge difference anyway.
