AMD vs. Intel Laptops Platform Analysis
 

Last week we posted an article comparing battery life using two different Gateway laptops - laptops that were essentially identical, with the exception of the motherboard, chipset, integrated graphics, and processor. This was a subject that we wanted to investigate closely for a long time, but acquiring laptops that are anywhere near "identical" when you are looking at two completely different platforms can be extremely difficult. Moreover, even companies that had very similar laptops didn't seem to have any desire to have us review their AMD models. Conspiracy theory, were they trying to avoid cannibalizing sales of more expensive laptops, or some other explanation… regardless of the cause, it took us many requests to finally have a mobile showdown between AMD and Intel.
