The 128GB iPad Air from Apple features an even thinner design than its predecessor. Dropping almost a quarter of the volume of the previous generation iPad, the iPad Air is just 7.5mm thin and weighs just 1 pound (1.05 pounds with cellular). Overall, the iPad Air is 28% lighter, 20% thinner and 24% less volume than the previous iPad. The iPad Air may be thinner and lighter, but it's still durable and solid. That's because it still has an aluminum unibody design. Apple introduces the 64-bit architecture to the iPad Air, which allows for more robust and powerful apps. Utilizing the A7 chip, the iPad Air runs apps faster and more efficiently than its predecessor. In fact, the A7 chip runs twice as fast as the A6X chip of the previous generation iPad. Also, the A7 chip supports OpenGL ES version 3.0 so the iPad Air can enable detailed graphics and visual effects once only possible on desktop computers and game consoles.
