In case you had any doubts,just unveiled at a media event in San Francisco a third-generation and boy does it have an ultra-high resolution display you’ve been clamoring for. ’s marketing honcho said “Until you see it, you can’t understand how amazing it is”. The screen itself packs in a It’s 20480-by-1536 pixel resolution, or 3.1 million pixels – “the most ever in a mobile device.”
This screen resolution on a 9.7-inch display translates onto a pixel density of 264 pixels per inch, less than the 326 pixels per inch on the/4S. However, when holding the device at 15 inches away ( is typically held at 10 inches away), your eye is unable to distinguish the individual pixels – hence the Retina moniker.
We’re allowed to call 264 pixels per inch Retina because you hold it further from your face.
Another interesting thing: With a 20480-by-1536 pixel resolution, the3 has a million more pixels than your HD TV. It’s also got 44 percent greater saturation. And to drive all those pixels, Apple upgraded the processor with quad-core graphics, naming the enhanced chip the A5X. Executives bragged on stage that the device has more memory and higher screen resolution than an Xbox 360 or PlayStation 3 console.
