Things really start to diverge under the hood. The fourth-gen iPad is two full processor generations ahead of the mini, which is actually on par with the second-gen iPad 2. The smaller tablet uses the dual-core A5 processor, whereas the newest iPad uses the dual-core A6X processor with quad-core graphics. That's four processing cores dedicated to graphics processing compared with the mini's two. Granted, much of the A6X's extra horsepower drives that incredibly high-resolution screen, but it also gives the full-size iPad an aptitude for impressive gaming and other image-intensive applications. The mini can only boast two dedicated graphics processing cores.
