Apple‘s newly unveiled iPad mini 3 boasts a stunning 7.9‑inch Retina display, an incredibly powerful A7 chip, advanced wireless technologies, and Touch ID. To ensure the Retina display in iPad mini 3 was sharp and vivid, Apple had to pack every one of the 3.1 million pixels from the 9.7-inch iPad into a 7.9-inch display. With a 2048-by-1536-resolution display, more pixels and more signals are placed closer together on the same plane, so signals can get crossed and image quality can suffer. To ensure everything on iPad mini 3 looks crystal clear, Apple engineers elevated the pixels onto a different plane — separating them from the signals. In the end, the pixel density jumped to 326 pixels per inch — so dense the human eye can’t distinguish individual pixels — making everything look incredibly detailed, vibrant, and razor sharp. The new iPad mini 3 comes in silver, space gray, and for the first time, gold. iPad mini 3 starts at $399 USD and will be available online beginning October 17.
