Apple claims the iPhone 5 is twice as fast as the iPhone 4S (which is no slouch) in terms of processing and graphics power, thanks to the in-house designed A6 chip. You could even say that the A6 pushes the iPhone 5 ahead of competing smartphones, at least in Javascript and Geekbench tests.
The A6 is clearly a beast of a chip, not just in terms of sheer power but also in delivering the world’s first phone powered by ARM’s Cortex-A15 CPU platform, completely customized to Apple's needs. In addition to two CPU cores, the first diffusion image by UBM TechInsights has also showed three GPUs.
And now, repair wizards iFixit teamed up with chip experts Chipworks who put the A6 silicon under a sophisticated microscope. Here's what we could glean from so-called "floorplans"...
