I was looking into getting a laptop and saw this compaq with an ATI radeon mobility with 64 megs of shared ram. Is this better than the ati radeon 7500 with 32 megs or a geforce4 go 420 with 16 megs of ram?
Unless it says Radeon somewhere in the description, then it's using the old Mobility chip and not any of the Radeon Mobility chips and thus is slower. The fastest laptop video chip is the Geforce4 Ti4200 based one. It's not quite as fast as the desktop Ti4200, but it's miles ahead of any other notebook video solution, at least until ATi makes a Mobility 9500 or 9600.
