Falling into the speeds and feeds trap when discussing mobile devices can be tricky, especially when the specs that smartphone vendors share most frequently only paint a small piece of the picture. It’s easy to look at things like CPU cores and clockspeeds and make assumptions, but dozens of factors contribute to a smartphone’s performance. Case in point: when the 1.3GHz dual-core A7 processor powering the new iPhone 5s is lined up on paper against quad- and eight-core CPUs clocked at more than 2GHz being used by Apple’s rivals, one might assume that the beastly chipsets powering various Android phones would have the upper hand. As it turns out, however, that assumption couldn’t be further from the truth. When Apple announced last week that its new iPhone 5s is powered by a new 64-bit A7 processor, people scoffed and said that without 4GB of RAM, the upgrade would barely make a difference.
