Apple Announces iPad Air and iPad mini with retina display.

The new iPad mini with Retina display packs all the 3.1 million pixels (2048-by-1536 resolution) of iPad Air into its 7.9-inch Multi-Touch™ display, for a pixel density of 326 pixels per inch. The 7.9-inch Retina display of iPad mini is 35 percent larger than screens on 7-inch tablets, and is the only small tablet to deliver the full iPad experience, now with razor sharp Retina quality. Images are crisp, text is crystal clear, movies play at full 1080p HD-resolution and the 475,000 apps designed specifically for iPad work automatically.

The A7 chip in iPad Air and iPad mini with Retina display offers 64-bit desktop-class architecture, advanced graphics and improved image signal processing from previous generations. With up to twice the CPU and graphics performance on iPad Air, and up to four times the CPU and eight times the graphics performance on iPad mini with Retina display, almost everything you do is faster and better than ever, from launching apps and editing photos to playing graphic-intensive games—all while delivering all-day battery life. The A7 chip’s 64-bit architecture and support for OpenGL ES version 3.0 unlocks game console-like visual effects. The new iPads also feature the M7 motion coprocessor that gathers data from the accelerometer, gyroscope and compass to offload work from the A7 for improved power efficiency.

Both new iPads feature two antennas to support Multiple-In-Multiple-Out (MIMO) technology, bringing twice the Wi-Fi performance to iPad Air and iPad mini with Retina display at a blazingly fast data rate up to 300 Mbps.² Cellular models also come with expanded LTE coverage to accommodate even more LTE networks worldwide, while continuing to deliver comprehensive support for other fast cellular technology around the world (DC-HSDPA, HSPA+), all in a single model.³
