9.7" Multi-Touch IPS LCD Retina Display 2048 x 1536 Native Resolution Dual-Core Apple A7 CPU with M7 Chip 802.11a/b/g/n Wi-Fi, Bluetooth 4.0 Lighter, Thinner Design Front 1.2-Megapixel FaceTime HD Camera Rear 5-Megapixel iSight Camera Gyro, Accelerator, Ambient Light SensorThe 16GB 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.The A7 chip is accompanied by the M7 coprocessor, which measures the motion of the iPad Air. By pulling data from the accelerometer, gyroscope and compass, it lightens the load of the A7 chip. This frees up the A7 chip to focus on processing multiple tasks and maintaining fast performance. Even though the iPad Air is 20 percent thinner and more powerful, it still manages to maintain its 10-hour battery life. That's because the A7 chip isn't just more powerful, it's also more efficient.The iPad Air also gives twice the Wi-Fi performance, thanks to dual antennas with MIMO (multiple-input multiple-output) technology. With dual-band 2.4 GHz and 5 GHz 802.11a/b/g/n Wi-Fi, the iPad Air can reach download speeds of up to 300 Mbps, which is double the data rate of the previous-generation iPad.
