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.

After the initial article went up dissecting battery life under a variety of situations, we have received numerous emails questioning our test methodology, complaining of bias for or against AMD/Intel, and offering other suggestions for how to improve the tests. The battery life article was always intended to be a short preview, and we are well aware of many of the differences between AMD and Intel platforms. This, then, is the rest of the story where we look at general application performance, graphics performance, and provide a full review of both laptops. First, let's start with a recap of the test systems - this time with full specifications.

In terms of core paper specifications, the systems really are as close to identical as we can get. There are no AMD chipsets for current Intel processors, and likewise Intel doesn't make chipsets for AMD processors. We could try to go the discrete graphics route, but virtually all current AMD-based laptops include integrated graphics and that's part of the features equation. We're looking not just at the difference in processors but what the mobile platform as a whole offers from each company. Those familiar with current trends should have an idea of what to expect: Intel has the better processor (faster and lower power), overall chipset features are similar, and AMD (courtesy of ATI) has the better integrated graphics. The question isn't so much who will be faster in various tests, but rather how much faster. That's what we're here to find out.
