Amd wifi vs centrino 2

The wifi will be completely dependent on a bunch of factors. Firstly how far you are from the access point, whether the card and router being used are G,B or N class, the length of the antennas and their routing inside the machine, the chipset being used for the wireless card. There are so many factors to consider that it would be impossible to really answer that question in a single post without comparing 100's of different configs as well as 4 or 5 major wireless chipsets,various standards etc.

Basically for the most part though most laptops assuming the standard (G,B,N) is the same and the router being used matches the wireless card in standard whether the laptop has the centrino 2 label or not won't really matter. All that means is that the cpu,motherboard and wireless chipset are all intel parts nothing more. Centrino is nothing but a marketing gimmick to milk the consumer for more money. The range isn't going to vary much no matter what really though.
