With a new A8X chip built on second-generation 64-bit desktop-class architecture, iPad Air 2 is the fastest, most powerful iPad ever. Compared with the A7 chip in the previous iPad Air, the new A8X chip delivers 40 percent faster CPU performance. With this kind of performance, you might expect a compromise or two. Like a bigger form factor or a shorter battery life. But iPad Air 2 is both thinner & lighter than the previous iPad Air. & thanks in part to the M8 motion coprocessor; it still has an incredibly long 10-hour battery life. So you can do more while carrying less. The new i Sight camera is the best iPad camera yet, with advanced optics, an enhanced sensor & a powerful Apple-designed image signal processor. There are new features like panorama, time-lapse videos, slo-mo, & burst & timer modes. The front-facing Face Time HD camera has been redesigned too, with an enhanced sensor & larger pixels for even better low-light performance. To create the astonishingly thin silhouette of iPad Air 2, Apple redesigned the Retina display, fusing what had been three layers into one. Not only did this make the display 18% thinner, it made it better, with more vivid colours & greater contrast & adding an anti-reflective coating, making it the least reflective display of any tablet in the world.
