Alright ,so I went to several stores and checked out laptops with Ati Radeon 3200/4100/4200 graphic cards. I know all of the above are integrated GC's. But on some machines, Win 7 showed 256MB Ram of dedicated memory while on some, it didnt. Can integrated cards have dedicated memory, if yes, does it make them a little more efficient?
Yes they do have dedicated memory in some instances and it will definately make the laptop more efficient. But you should also look for something with at least 512mb dedicated memory to really see the difference in performance.
